AGREEMENT FOR SERVICES

This Agreement for Services (“Agreement”) is entered into by and between Intrado Inc. (“Intrado”) and the party signing below (“Customer”), as of the April 27, 2005.  This Agreement consists of these terms and conditions and any order, statement of work, exhibit, or similar document executed under this Agreement (each, an “Attachment”).  Intrado and Customer are referred to herein collectively as “Parties” and individually as “Party.”

1.    SERVICES.  Intrado will provide to Customer the services specified in Attachment A - VoIP 9-1-1 Gateway Services with V9-1-1^SM Mobility Services for City of New York Statement of Work for Vonage Network Inc. and Attachment B - VOIP V9-1-1^SM Mobility Services for Vonage Network Inc. (“Services”).

2.    TERM.  This Agreement will commence as of the date first set forth above and, as to each Attachment, will continue until the expiration or termination of such Attachment.

3.    PAYMENT.

a.    Customer will pay the fees described in the Attachment.  Except as specified in the applicable Attachment, (i) recurring fees will be billed monthly; (ii) non-recurring fees will be billed within thirty (30) days of the applicable Attachment effective date; and (iii) except with regard to disputed amounts as permitted in 3(d below, all invoices will be due and payable within thirty (30) days of invoice date.  If Customer generates purchase orders, Customer will use commercially reasonable efforts to provide appropriate purchase orders to Intrado.

b.    Customer will bear all taxes, duties, and other government charges imposed on Customer’s purchase of the Services (including interest and penalties to the extent caused by Customer’s actions or omissions), except taxes based on Intrado’s income, employment or property.  Customer will support any Customer claim of tax exemption with appropriate documentation.

c.    Interest will accrue on past-due balances as of the date of delinquency at the lower of:  (i) one-half percent (0.5%) per month, or (ii) the highest rate permitted by applicable law.  If Services are discontinued due to nonpayment of fees and subsequently recommenced, a reconnection fee or deposit will apply, in addition to applicable interest and will be provided to Customer prior to any such reconnection.

d.    If Customer disputes an invoice in good faith, Customer may withhold the disputed amount, not to exceed one month’s recurring fees for such Service, provided that Customer must:  (a) notify Intrado within thirty (30) days of any such invoice, specifying the nature of the dispute or inaccuracy; and (b) pay any undisputed amounts as provided herein.  Both Parties will in good faith investigate and attempt to promptly resolve any disputed invoices.  Once resolved, Customer will promptly pay any amounts owed and Intrado will promptly refund any amounts it has collected to which it is not entitled.

e.    No set-off, deduction, or cross-collateralization will be permitted hereunder.  However, Intrado may require prepayment or additional security if Customer becomes insolvent, is unable to pay its debts when due, or is the subject of a bankruptcy or receivership proceeding.

4.    CONFIDENTIALITY.

a.    During the course of this Agreement, either Party may receive or have access to Confidential Information of the other.  “Confidential Information” means any confidential information or data disclosed by a Party (“Disclosing Party”) to the other Party (“Recipient”) under or in contemplation of this Agreement, which (a) if in tangible form or other media that can be converted to readable form is clearly marked as Confidential, proprietary, or private when disclosed; or (b) if oral or visual, is identified as Confidential, proprietary, or private on disclosure or (c) if not so marked or identified, is such that a reasonable businessperson would understand it to be confidential by reason of its nature or content.  The terms “Disclosing Party” and “Recipient” include each Party’s corporate affiliates that disclose or receive Confidential Information.  Each Party will cause its affiliates to comply with the obligations of this Section 4, and each Party agrees that it is responsible for its affiliates’ compliance with this Section 4.  Actions or omissions by a Party’s affiliate, that if taken by said Party would constitute a breach of this  

Pages where confidential treatment has been requested are stamped, "Confidential treatment has been requested. The redacted material has been separately filed with the Commission." All redacted material has been marked by an asterisk (*).

Section 4, will be considered actions or omissions of said Party.  The Recipient acknowledges the economic value of the Disclosing Party’s Confidential Information.  The Recipient therefore, will:  (i) use the Confidential Information only in connection with the Recipient’s performance of its obligations or in exercising its rights under this Agreement; (ii) restrict disclosure of the Confidential Information to employees of the Recipient and its affiliates with a “need to know” and not disclose it to any other person or entity without the prior written consent of the Disclosing Party; (iii) advise those employees who have access to the Confidential Information of their obligations with respect thereto; (iv) treat the Confidential Information with at least the same degree of care to avoid disclosure to any third party as is used by Recipient with respect to its own information of like importance which is to be kept secret; and (v) copy the Confidential Information only as necessary for those employees who are entitled to receive it and ensure that all confidentiality notices are reproduced in full on such copies.

b.    For the purposes of this Section 4 only, “employee” includes third parties retained by the Parties for temporary consultative, administrative, clerical, programming or related Services support.  A “need to know” means that the employee reasonably requires the Confidential Information to perform his or her responsibilities in connection with this Agreement.

c.    “Confidential Information” will not include, and the obligations of this Section 4 will not apply to, any information or data which the Recipient can demonstrate:  (i) is or becomes available to the public through no breach by Recipient of this or any other agreements between the Parties; (ii) before its disclosure hereunder, was known by the Recipient without any obligation owing to the Disclosing Party (directly or indirectly) to hold it in confidence; (iii) is received from a third party who does not owe any duty to the Disclosing Party (directly or indirectly) with respect to such information; (iv) is independently developed by the Recipient without the use of Confidential Information of the Disclosing Party; or (v) is approved for release by written authorization of the Disclosing Party but only to the extent of such authorization and without any disassembly, reverse engineering, or similar undertaking by Recipient.  If Recipient is required by law or regulation to disclose Confidential Information of the Disclosing Party, Recipient may do so, but only to the extent and for the purposes of such required disclosure, and only if the Recipient first promptly notifies the Disclosing Party of the need for such disclosure and allows the Disclosing Party a reasonable opportunity to seek an appropriate protective order.

d.    Confidential Information, including copies, will be deemed the property of the Disclosing Party.  The Recipient will, within twenty (20) days of a written request by the Disclosing Party return all Confidential Information (or any designated portion thereof), including all copies thereof, to the Disclosing Party or if so directed by the Disclosing Party, destroy such Confidential Information.  The Recipient will also, within ten (10) days of a written request by the Disclosing Party, certify in writing that it has satisfied its obligations under this Section.

e.    Each of the parties acknowledges and agrees that irreparable harm could result if any obligation under this Section 4 is not performed by a Recipient and accordingly, the Disclosing Party shall be entitled to seek such injunctive or equitable relief as may be deemed proper by a court of competent jurisdiction to prevent disclosure of its Confidential Information.  The Disclosing Party shall not be deemed to have made an election of remedies by obtaining, or seeking to obtain, injunctive or equitable relief.

5.    LIMITED WARRANTY.

a.    Intrado warrants that Services (i) will meet the applicable specifications in the Attachment(s); and (ii) will be provided in a professional and workmanlike manner by individuals with suitable skills and abilities.  Intrado will use commercially reasonable efforts to re-perform any Services not meeting this limited warranty promptly following notice from Customer.  Intrado does not warrant products, equipment, hardware, or software not manufactured or developed by Intrado, but will, to the extent permitted, assign to Customer any warranties given to Intrado by the applicable vendor(s).

b.    EXCEPT AS EXPRESSLY PROVIDED HEREIN, INTRADO MAKES NO EXPRESS OR IMPLIED WARRANTIES, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NONINFRINGEMENT.  THE REMEDY STATED ABOVE IS CUSTOMER’S SOLE REMEDY FOR A BREACH OF WARRANTY.  INTRADO EXPRESSLY DENIES ANY REPRESENTATION OR WARRANTY ABOUT THE ACCURACY OR CONDITION OF DATA OR THAT THE SERVICES OR RELATED SYSTEMS WILL OPERATE UNINTERRUPTED OR ERROR-FREE.

6.    LIMITATION OF LIABILITY.

a.    NEITHER PARTY WILL BE LIABLE TO THE OTHER FOR ANY INDIRECT, SPECIAL, CONSEQUENTIAL, INCIDENTAL, OR PUNITIVE DAMAGES, INCLUDING COST OF COVER.  EACH PARTY’S ENTIRE AGGREGATE LIABILITY FOR ANY CLAIMS RELATING TO SERVICES OR THIS AGREEMENT WILL BE LIMITED TO AN AMOUNT EQUAL TO THE SUM OF THE FEES PAID BY CUSTOMER FOR THE APPLICABLE SERVICES IN THE TWELVE MONTHS IMMEDIATELY PRECEDING THE DATE OF THE RELEVANT CLAIM.

b.    THE FOREGOING LIMITATIONS AND EXCLUSIONS OF LIABILITY WILL NOT APPLY FOR CLAIMS RELATING TO VIOLATIONS OF EITHER PARTY’S INTELLECTUAL PROPERTY RIGHTS (INCLUDING SOFTWARE), OR ANY OF EITHER PARTY’S OBLIGATIONS SET FORTH IN THE SECTIONS HEADED “CONFIDENTIALITY” AND “INDEMNIFICATION”, AND MAY BE FURTHER LIMITED BY FEDERAL, STATE OR LOCAL LAW.  EXCEPT AS SET FORTH IN THE PRECEDING SENTENCE, THE FOREGOING LIMITATIONS OF LIABILITY WILL APPLY, HOWEVER, WHETHER THE APPLICABLE CLAIM IS BASED ON LOST GOODWILL, LOST PROFITS, LOSS OF USE OR PERFORMANCE OF ANY PRODUCTS, SERVICES, OR OTHER PROPERTY, LOSS OR IMPAIRMENT OF DATA OR SOFTWARE, OR OTHERWISE, AND WHETHER THE APPLICABLE CLAIM ARISES OUT OF BREACH OF EXPRESS OR IMPLIED WARRANTY, CONTRACT, TORT, (INCLUDING NEGLIGENCE), STRICT PRODUCT LIABILITY OR OTHERWISE, REGARDLESS OF WHETHER SUCH PARTY HAS BEEN NOTIFIED OF THE POSSIBILITY OF SUCH DAMAGES OR IF SUCH DAMAGES WERE REASONABLY FORESEEABLE.

7.    INDEMNIFICATION.  Intrado and Customer each agrees to indemnify and hold harmless the other, its respective officers, agents, employees, contractors, subcontractors, suppliers, invitees, and representatives, from and against any and all third party claims, including without limitation claims by Customer’s customers, of loss, damages, liability, costs, and expenses (including reasonable attorneys’ fees and expenses) for physical injury or death or damage to real property to the extent caused by the indemnifying Party’s negligence, and/or willful misconduct.  In addition, Intrado shall indemnify, defend, and hold harmless Customer and its Affiliates, directors, officers, employees, agents, successors and assigns from all claims of patent or other intellectual property infringement arising from the use of the Services or software provided by Intrado.  (Whenever Intrado is responsible under the preceding sentence, Intrado may at its option either procure the right for Customer to continue using, or may replace or modify the alleged infringing Service or Software so that the Service or Software becomes noninfringing.  If those alternatives are not reasonably achievable, Intrado may terminate the affected Attachment without termination liability to either Party.  If the indemnifying Party acknowledges in writing its obligations under this Section, the indemnifying Party will have the right to conduct the defense of such claim or action and all negotiations for settlement or compromise.  However, the indemnified Party, at its own expense, may participate in the defense of any such proceeding through counsel of its choosing.

h.    Assignment.  This Agreement will be binding on the successors and assigns of both Parties, provided, however, neither party may assign, delegate or transfer this Agreement (an “Assignment”) without the other party’s prior written consent.  Such consent will not be required, however, for any Assignment to a financially solvent affiliate of the assigning party or an assignment involving a sale of all or substantially all of Customer’s assets or stock, or any company with which or into which Customer may merge or consolidate.  Any other assignment or transfer will be void and of no effect.

i.     Governing Law; Venue.  This Agreement and all acts, transactions, rights, and obligations relating thereto will be governed by and construed under the laws of the State of New York, without giving effect to principles of conflicts of law.  All disputes will be resolved exclusively in the federal or state courts located in New York, New York, and each Party consents to the personal jurisdiction and exclusive venue of those courts for that purpose.

j.     Remedies.  Either Party will be entitled to immediate injunctive relief in addition to any other rights and remedies available to it at law or in equity, without the posting of a bond or demonstration of irreparable harm, for breach by the other Party of Section 4 or 9 above.  Except as stated herein, the rights and remedies of each Party are cumulative, and are in addition to any other rights or remedies available at law or in equity.

k.      Laws, Regulations, Permits.  Each Party will comply, at its own expense, with all applicable federal, state, county, and local ordinances, regulations, and codes in performing its obligations hereunder.  Each Party represents that it has or will obtain all consents, licenses, permits and certificates required to receive or perform the Services and to do business in the United States.  If continued performance of the Services would cause Intrado or Customer to be in violation of any applicable law, statute, ordinance, court order or regulatory agency rules, either Party may cease performing the applicable Service(s) to the extent reasonably required to correct or avoid the violation,

l.     Advertising And Publicity.  Except for materials already made public, neither Party will distribute any news releases, articles, brochures, speeches, or advertisements concerning this Agreement, nor use the other Party’s

The following are attached to this SOW and are incorporated herein:

The Services Intrado provides under this SOW will enable the routing of Customer’s VoIP Subscribers’ VoIP 9-1-1 emergency calls to the appropriate PSAP through delivery of the VoIP 9-1-1 call to the SR(s) on behalf of the Customer or through delivery of information back to Customer’s call control platform with routing instructions for proper termination. The V9-1-1 Mobility service will enable the VoIP 9-1-1 call to be delivered to the PSAP with the VoIP Subscriber’s call back number and MSAG valid address, when available.

The Services will provide a native E9-1-1 solution for delivering VoIP 9-1-1 calls from both in-region and out-of-region TNs (i.e., from TNs that are ordinarily assigned within the PSTN to locations within the serving territory of the applicable PSAP (“in-region TNs”) and TNs that are not ordinarily assigned within

1

the PSTN to locations within the serving territory of the applicable PSAP but are used by Vonage in serving VoIP Subscribers located within such territory (“out-of-region TNs”). The Services will provide the Customer with a near real-time provisioning interface to provision/register Subscriber location data. At the time of a 9-1-1 call Intrado will:  (i) whenever feasible, provide call routing instructions to the Customer which will contain a ten (10) digit Emergency Services Routing Number (“ESRN”) and ten (10) digit Emergency Services Query Key (“ESQK) as the Calling Party Number (“CPN”), or (ii) when (i) is not feasible, deliver the VoIP 9-1-1 call to the appropriate PSAP on behalf of the Customer utilizing one (1) or multiple existing business agreements and partnerships and/or dedicated IP infrastructure (i.e., Intrado’s VoIP 9-1-1 Peering Service) deployed by Intrado.

To receive the Services, the Customer will do the following:

1.      Provide Subscriber Records containing the TN and an accurate physical service address (as provided to Customer by Subscriber) with the five (5) digit zip code.

2.      Comply with the interface specification for provisioning Subscriber data, described in Appendix D attached hereto.

2           Additional Terms and Conditions

In addition to the terms and conditions of the Agreement, the following additional terms and conditions shall apply to this SOW.

2.1          Term

The term of this SOW shall begin upon the SOW Effective Date as first stated above and continue for a period of three (3) years (“Initial Term”) unless earlier terminated under the terms of this SOW or the Agreement. The Initial term may be extended at Vonage’s option for successive additional one (1) year terms (each, a “Renewal Term”).

2.2          Termination

Customer may terminate for convenience at any time, provided Customer will pay a termination fee (which will be Intrado’s sole and exclusive remedy for such termination) equal to *.

2.3          Exclusivity and Competition

Nothing herein shall prohibit Intrado from providing services similar or identical to the Services provided to Customer hereunder to any other entity or person, whether or not such services are utilized for emergency purposes; provided, however, that Intrado does not use Confidential Information of Customer to do so. Nothing herein shall prohibit Customer from procuring services similar or identical to the Services provided by Intrado hereunder from any other entity or person, whether or not such services are utilized for emergency purposes; provided, however, that Customer does not use Confidential Information of Intrado to do so.

2.4          Letter of Agency

Concurrent with the execution of this SOW, or at any time during the Initial Term or any Renewal Term, Customer agrees to execute and deliver to Intrado, such Letter of Agency (“LOA”) as may reasonably be required, which LOA will enable Intrado, as a limited agent for Customer, to work with telecommunications carriers on the Customer’s behalf solely for the purpose of establishing interconnections between Intrado, Customer, and/or the telecommunications carriers required for Intrado to provide and Customer to receive Services hereunder. The LOA shall:  (1) not be released by Intrado or used except as authorized by this SOW; (2) be deemed revoked upon:  (i) delivery to Intrado or the applicable telecommunications carrier of written notice of Customer’s election in this regard or (ii)

* Confidential treatment has been requested. The redacted material has been separately filed with the Commission.

2

termination or expiration of this SOW, whereupon Intrado shall cease to act under such :LOA or represent itself as Customer’s agent or representative for any purpose whatsoever; and (3) be returned to Customer upon Customer’s request, upon:  (i) termination or expiration of this SOW; or (ii) delivery of a revocation notice to Intrado as described herein. In no event shall Intrado be deemed Customer’s agent (nor shall Intrado represent itself as such) for purposes of responding to or interfacing with PSAPs impacted by the routing and delivery of Subscriber calls. The Parties understand and acknowledge that should Customer fail to provide Intrado with such an LOA, portions of the Services may not be able to be provided to the extent Intrado cannot reasonably provide such Services in the absence of such an LOA.

3           Services Overview

3.1          Provisioning Flow

The Customer will provision Subscriber data into the Intrado Services systems, and Intrado will receive such Subscriber data, by means of a validation and update interface (“VUI”), a real-time Extensible Markup Language (“XML”) based transactional interface. The following describes the provisioning process.

3.1.1         VUI

The VUI setup and interface specifications, attached hereto as Appendix C and Appendix D, provide setup instructions for establishing the Customer account and facilitating Subscriber Record transactions.

1.      Customer submits an XML formatted message set which will contain a Subscriber base record to Intrado via the VUI.

2.      Intrado geo-coding process adds x, y (latitude-longitude) coordinates to the Subscriber base record. Records that fail the geo-coding process are sent to Intrado data integrity unit analyst for error processing. Address errors that cannot be resolved by Intrado will be sent back to the Customer for further resolution.

3.      Subscriber base record is matched by Intrado against the MSAG for MSAG validation. Upon successful MSAG validation, Intrado provisions the Subscriber base record on Intrado’s Services system. If MSAG validation fails, the Subscriber base record is sent to an Intrado data integrity unit analyst for error processing.

4.      Subscriber base records are inserted, deleted, or changed by the Customer through the agreed upon provisioning interface (VUI), within the Subscriber database on Intrado’s Services provisioning systems.

5.      All Subscriber base records in error, once processed by Intrado, will be sent by Intrado to an Intrado data integrity unit analyst for resolution and resubmitted to Intrado’s Services provisioning systems as soon as error processing is complete. Upon processing and correction of error Intrado will immediately resubmit record into Intrado systems.

9           Services Limitations

Customer understands, acknowledges, and accepts the following limitations of Intrado’s Services:

•       For Customer’s VoIP Subscribers:

a.      The real-time provisioning interfaces provided with the Services allow the Customer to submit Subscriber Records for Services provisioning which enables the Services call to be routed to the appropriate PSAP and present call back number and MSAG valid physical service address of Subscriber to the PSAP. In the event of a geo-coding or MSAG validation failure, Intrado cannot process the error records in real time and will use commercially reasonable efforts to resolve the records in error as soon as possible. There may be circumstances beyond Intrado’s control that will prevent an Intrado data integrity unit analyst from correcting geo-coding and or MSAG validation errors in the event the Subscriber’s physical service address is a new address causing delays in provisioning the Subscriber’s data into Intrado’s Services provisioning systems.

b.     The Services is predicated on using primary wireline PSAP boundaries for routing Services emergency calls to the appropriate PSAP. The primary wireline boundary information is collected by Intrado and is entered into a database for real time queries for PSAP boundary lookup. Customer acknowledges that, due to circumstances beyond Intrado’s control, primary wireline PSAP boundary data may not be available for the entire United States and that Intrado is dependent on the PSAPs to provide such information resulting in the use of wireless PSAP boundary data to route a VoIP emergency call.

•       For emergency call routing using Intrado’s ECRC, in the event (i) caller cannot speak or identify their address, (ii) data connectivity between the Customer VoIP Subscriber address database and the ECRC is interrupted, (iii) ANI is not provided, and (iv) Customer’s NOC cannot provide the Customer VoIP Subscriber’s location information, Customer acknowledges that Intrado has no further ability to assist the caller.

10          Training

As part of the cost of Services, Intrado will provide two (2) hours of training via telephone on how to transmit data, submit additional records, and Intrado escalation procedures. All training conducted by Intrado will be customized to meet the needs of Customer. The trainer will use customized training examples to familiarize Customer with Intrado’s system and procedures. Training will be “train-the-trainer” format, which will enable Customer to train new employees.

Customer and Intrado will mutually agree on and schedule training.

11          Authority

Each Party represents to the other that (i) it has full authority to enter into and perform under this SOW; (ii) the person signing this SOW on its behalf is properly authorized; and (iii) it has read this SOW, understands it, and agrees to be bound by all of its terms, conditions, and provisions.

12          Entire Agreement

This SOW shall not be enforceable unless duly executed by both Parties. This SOW, together with any Appendices hereto and the Agreement, constitutes the Parties’ entire understanding related to the subject matter of this SOW and supersedes any prior written or oral agreements or understandings with regard to the subject matter of this SOW.

Introduction

Intrado’s Validation and Update Interface (VUI) allows client-side software to validate and update information used in E9-1-1 systems. VUI implements a specific set of XML messages that allows for all information required by E9-1-1 systems to be pre-validated, authenticated, formatted, and delivered to the appropriate destination databases. This may include Selective Router (SR) and Automatic Location Identification (ALI) databases (refer to your product-specific documentation for more information).

VUI uses digital certificates to verify that users sending messages are who they claim to be, and to provide the receiver with the means to encode a reply.

1.0    Scope and Content

1.1          Introduction

The Validation and Update Interface (VUI) specification is designed to facilitate application vendors in the provisioning of enhanced 9-1-1 (E9-1-1) services when producing software that supports residential and commercial local exchange service subscribers, Voice over IP (VoIP) subscribers, and users of corporate and institutional Multiple Location Telephone Service (MLTS) systems. Every telecommunications service provider providing dial tone is required by state and local regulators to provide E9-1-1 services to their customers. Using this interface, application vendors can substantially automate the process of efficiently provisioning E9-1-1 services while meeting the regulatory requirements and thereby reducing costs.

The Validation and Update interface implements a set of messages that allows for all information required by the E9-1-1 systems to be pre-validated, authenticated, formatted, and delivered to the appropriate destination databases (for example, Selective Router (SR) and ALI databases). This interface specification draws upon currently recognized standards in the industry including those from the National Emergency Number Association (NENA).

This specification documents the following interconnects to the Validation and Update Interface system: the application, database, and authentication servers; gateways; and devices necessary to provide a robust platform for the provisioning of E9-1-1 data with the service provider’s system. The Intrado E9-1-1 interface supports online connectivity for batch and near real-time transaction processing. Standard e-business protocols such as XML over HTTP allow access to the Validation and Update system. The Intrado system ensures database updates are distributed through the network in accordance with standard provisioning mechanisms and fed into the appropriate destination databases based upon customer type (traditional wireline or VoIP subscriber). This interface anticipates the client-side code will manage all direct interaction with the user of the application and will use the Validation and Update Interface system to provision the E9-1-1 services for the subscriber or user.

This specification implements all functions a telecommunications service provider or PBX user needs to be in full compliance with the FCC mandates for E9-1-1 and meets the demanding requirements of Incumbent Local Exchange Carriers (ILECs), Competitive Local Exchange Carriers (CLECs), and Wireless Carriers. The end users of the applications developed using this interface will be Alternative Local Exchange Carriers, Building Local Exchange Carriers, and Data Local Exchange Carriers.

1.2    System Access

The Validation and Update Interface is called via an XML-formatted request transmitted via the HTTP protocol.

The Validation and Update Interface requires transmission of E9-1-1 and subscriber TN data over secure network connections in order to protect customer privacy. Unsecured connections over the public Internet (FTP, SMTP) are not supported, and 128-bit encryption is the minimum supported for public Internet connections.

Messages sent to Intrado are authenticated using the customer’s account number and a client-side digital certificate. Intrado issues an account number to each registered customer, which is a required element of each request sent by the customer.

Intrado’s network engineering and network security groups evaluate and approve all proposed network topologies prior to implementation.

2     System and Network Overview

This section describes the Validation and Update Interface standards.

2.1    System Performance

The customer can expect between two and thirty-second transactional response times to the online transactions listed within this specification. Batch transaction performance will depend on file size, system availability, and query types.

2.2    System Date and Time

All date and time elements within this interface are represented using coordinated universal time (UTC) in order to have a common reference point regardless of location of sending or receiving system. Systems operated by Intrado are referenced to the National Institute of Standards and Technology (NIST) atomic clock via radio.

3     XML Message Formats

3.1    General XML message format

All VUI XML request and response messages are contained in the following general structure. All tags are required. Public XML schema files are provided separately.

<VUI

ver=“1.0”

xmlns=“http://www.intrado.com/namespaces/vui”

xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=“http://www.intrado.com/namespaces/vui

http://vuitest.intrado.com/schema/VUI.xsd” >

<HDR>

<Acct>customer account ID</Acct>

<ClientVersion>client software version</ClientVersion>

<REC>number of requests in the message payload</REC>

</HDR>

<Payload>

[actual VUI request information message]

</Payload>

<TRL>

<REC>number of requests in the message payload</REC>

</TRL>

</VUI>

All requests to VUI must use this structure. Individual request structures are described in subsequent sections.

Upon receipt, all messages are checked against an XML schema, which is provided via the Intrado web site. Those schema files are the sanctioned VUI message specifications.

The HDR and TRL tags are included to implement the NENA message specification. Both the HDR and TRL sections must include a REC tag, which specifies the number of records included in the Payload section of the request and response documents. In request messages, the REC tag should always contain the number “1”. In responses, this value indicates the number of responses from a query request, or “1” for most other messages.

The Acct and ClientVersion tags contain information that Intrado uses to route requests and identify customers. Your Intrado account representative provides this information.

All alpha characters to VUI must be uppercase. The system will upshift alpha characters if they are submitted in lower case, except in cases where valid values for the data element have been defined within this specification. If lower case alpha characters are submitted within the FOC, PRD, POD, STA, or CLS fields, the XML request message will not pass the XML schema validation.

Empty-element tags may be used for any element that has no content and as such are disregarded by VUI except in cases where element content is required.

Several additional requirements on VUI XML message contents have been set. There are several characters with special meanings that may not appear in an XML document, including the. A full listing of invalid characters may be found in the W3C XML specification. These characters must be replaced as follows:

& becomes &amp;

<  becomes &lt;

6

Also, a VUI XML request message may not contain a CDATA section—special characters must be escaped individually as described above. Most XML libraries perform this modification automatically. Requests containing CDATA are rejected by our XML schema.

All responses from VUI to the customer use this structure:

<VUI ver=“1.0”>

<HDR>

<REC>[Response record count]</REC>

</HDR>

<Payload>

[Response message]

</Payload>

<TRL>

<REC>[Response record count]</REC>

</TRL>

</VUI >

3.2    Error Response

If the VUI system receives an XML message it is unable to parse, the following error message is returned in the Payload section of the standard response structure, described in Section 3.0:

<ErrorResponse ver=“1.0”>

<RC1 message=“UNABLE TO PARSE XML”>3</RC1>

<REQ><![CDATA[(original XML request message)]]>

</ErrorResponse>

The RC1 tag contains an error code and a detailed description of the parsing error, if possible (refer to Appendix A: Return Codes and Descriptions), and the REQ tag contains a CDATA-delimited copy of the original message to assist customers in troubleshooting their requests.

3.3    MSAG Query Request

The customer uses this transaction to request the MSAG data that matches their specified query criteria.

3.3.1    MSAG Query Request Structure

This message must be placed under the Payload tag in the standard VUI request message, described in Section 3.1.

<MSAGQueryRequest ver=“1.0” [required] recordLimit=“l00” [required, 1-999] continuation=“queryIdentification” [optional, refer to section 3.3.2] >

<HNO> [optional]

<PRD> [optional]

<POD> [optional]

<STS> [optional]

<STN> [optional if MCN is present, otherwise required]

<MCN> [optional if STN is present, otherwise required]

<STA> [required]

</MSAGQueryRequest>

The customer uses this transaction to request the MSAG data that matches their specified query criteria.

7

The STN and MCN tags may include wildcard characters. The asterisk (*) is the wildcard for any number of characters, and the question mark (?) is the wildcard to indicate any single character. An MSAG query must contain an STA tag and either an MCN or STN tag, with all other data tags optional.

NOTE:  The POD and STS fields are specified by the NENA recommendation but do not exist in Intrado’s MSAG database. When an MSAG query request is submitted, the fields are appended to the STN field. For example, if a request contains these fields:

<STN>MAIN</STN>

<POD>S</POD>

<STS>ST</STS>

the system will treat it as if the following was sent in:

<STN>MAIN ST S</STN>

Responses append the data contained within the POD and STS fields within the STN field.

Also, the Intrado MSAG database backend will attempt to find additional streets when a query produces no results. For example, if a query is sent in with the STN set to “MAIN”, the system may return results for “MAIN ST” and “MAIN AVE.” This may produce unexpected results in certain circumstances because of the behavior mentioned above. For example, if a request is sent in with these fields:

<STN>MAIN</STN>

<POD>S</POD>

the system will treat it as a request with the STN set to “MAIN S,” which will then return potentially misleading results for “MAIN ST.”

3.3.2    MSAG Query Response Structure

This structure is passed back to the customer in the Payload section of the standard VUI response structure, described in Section 3.1:

<MSAGQueryResponse ver=“1.0”>

<RC1 message=“SUCCESS”>0</RC1>

<MSAGData>

<PRD>

<STN>

<MCN>

<STA>

<COI>

<MSAGRange>

<LOR>

<HIR>

<OEI>

<EXC>

<ESN>

<SRT>

</MSAGRange>

</MSAGData>

[additional MSAGData sections for each result returned]

</MSAGQueryResponse>

The OEI tag will not be present in the response if the House Number Range is valid for both odd and even house numbers.

8

The RC1 tag indicates either success (0) when records have been returned or failure (1) if no records exist. If the query was performed successfully, one or more MSAGData tags are included in the message payload, representing the data queried.

The MSAGQuery returns a number of records up to the specified recordLimit. VUI may also limit the response size in order to optimize performance based upon the current number of simultaneous client systems and requests.

When the number of records that match the query exceeds what can be returned in a single response, a sequence of repeated identical queries may be used to retrieve all the records. The user-supplied continuation attribute identifies these related queries. Each query in the same continuation group begins where the previous query left off.

An RC2 tag is returned indicating either this response has returned the last set of records available (value 1) or that more records that match this query (value 0) are available.

Repeatedly sending in the same request with the same continuation attribute value continues to return the next set of records matching the query until RC2 indicates no more records are available (value 1):

<RC1 message=“SUCCESS>0</RC1>

<RC2 message=“Additional records found”>0</RC2>

<RC1 message=“SUCCESS. Additional records found>0</RC1>

<RC2 message=“Additional records found”>0</RC2>

…

…

<RC1 message=“SUCCESS>0</RC1>

<RC2 message=“No additional records exist”>1</RC2>

NOTE

1.  Several query sequences can be in progress at the same time by the user providing distinct continuation attribute values.

2.  The continuation mechanism is implemented using HTTP cookies. This requires the user application to return any cookies sent it in the subsequent continuation request.

3.4    MSAG Pre-Validation

The customer uses this transaction to request that Intrado perform an MSAG pre-validation of the specified address. If the pre-validation request data refers to one or more MSAG entries, the record is considered to be valid. If the request data refers to zero records, the record is considered to be invalid.

3.4.1    MSAG Pre-Validation Request

<MSAGValidationRequest ver=“1.0”>

<HNO> [required]

<PRD> [optional]

<POD> [optional]

<STS> [optional]

<STN> [required]

<MCN> [required]

<STA> [required]

<EXC> [optional]

</MSAGValidationRequest>

The behavior of the STS and POD tags is the same as in an MSAG query – see the note above.

9

3.4.2    MSAG Pre-Validation Response

If the MSAG data supplied is valid (meaning that it produces one or more MSAG street and range entries), the system responds with this message:

<MSAGValidationResponse ver=“1.0”>

<RC1 message=“VALID, one or more records found”>0</RC1>

</MSAGValidationResponse>

If the MSAG data supplied is NOT valid (meaning that it produces zero results), the system responds with this message:

<MSAGValidationResponse ver=“1.0”>

<RC1 message=“INVALID”>1</RC1>

</MSAGValidationResponse>

3.5    TN Query

The customer uses this transaction to request the TN data that matches their specified query criteria. Wildcard queries are currently not supported.

The customer only has access to TN data for the CPNs that they own.

3.5.1    TN Query Request Structure

<ALIQueryRequest ver=“1.0”>

<CPN>3035815600</CPN> [required]

</ALIQueryRequest>

3.5.2    TN Query Response

The behavior of the STS and POD tags are the same as in an MSAG query – see the note above.

3.6    TN Update

The customer uses this transaction to insert, change, or delete TN records in the TN databases.

The customer can only update TN data for the CPNs that they own.

3.6.1    TN Update Request Structure

<ALIUpdateRequest ver= “1.0” [required] FOC=“C” [required-refer to Section 4.0 for all valid entries]>

1.0          Overview

This specification describes the interface between a Call Processing Center (CPC)(1) and Intrado’s IntelliVector^SM Position Server (PS). This interface is called the Geographical Routing Interface using XML Elements (GRIXE). This interface is part of the network specification for delivery of emergency service calls from a CPC requiring routing instruction to the caller’s local Emergency Services Network(2). The specification supports parameters that would allow routing of the call as a native 9-1-1 call. The CPC vendor provides subscriber records of their customer base. The records include customer name, address, city, state, county, and zip code. The customer addresses are then geo-coded to provide latitude and longitude (X/Y) coordinates for each subscriber. The Telephone Number (TN), subscriber record, and X/Y coordinates are stored in the PS system. When an emergency call is received at the CPC, a query containing the caller’s TN is sent to the PS System over this new interface. Based on the received TN, the PS retrieves the X/Y coordinates. The Coordinate Routing Database (CRDB) is queried by the PS with those X/Y coordinates to determine the PSAP serving area and returns it to the PS. The PS uses the PSAP serving area received from the CRDB to determine the routing data for this call. The PS returns the routing data across the GRIXE interface to allow the CPC to route the call to the appropriate PSAP.

The protocol for this interface is XML message sets transported using Hypertext Transfer Protocol (HTTP) over TCP/IP. This protocol specifies the query and response messages and call termination message between the Call Processing Center and Position Server.

2.0          Protocol Stack

The protocol stack used for the GRIXE interface is shown in Figure 2-1. The XML encoded message content is transported using HTTP over TCP/IP. IP provides the capability to route the messages between the CPC and the PS. The intervening network elements (for example, routers and firewalls) need only use IP to correctly route the session setup message and subsequent packets.

IP provides a connectionless, “best-effort” delivery service. IP’s responsibilities include the transmission of a block of data received from upper layers as well as the message addressing. The combination of an IP header preceding a block of data constitutes a datagram. If a link layer failure occurs during datagram transmission, IP’s behavior rules do not specify that the datagram be present.

The transport layer (for example, TCP) is responsible for this datagram retransmission functionality. TCP provides a reliable, connection-oriented, byte stream, transport layer service. It provides the reliability by performing the following functions:

1.            Resizing application layer packets into the proper buffers for the network layer.

2.            Sending acknowledgments for each block of data received.

3.            Retransmitting unacknowledged data blocks.

4.            Making sure that the transmitted packets are received through the use of acknowledgement timers.

4

5.            Maintaining a checksum for the header and data.

6.            Discarding duplicate blocks of data.

7.            Providing flow control that prevents a faster host from overrunning a slower one.

HTTP is responsible for routing and encapsulating the XML content. It is a request/response protocol involving a server and a client. The CPC takes the role of the client and requester, and the PS is the server that responds to the messages. HTTP has the capability to provide a secure interface but, for the purpose of this interface, that capability is not required since the emergency service network is a secure private domain.

Figure 2-1: Logical Network Element Connectivity

The HTTP exchange, shown in Figure 2-2, between the CPC and the PS consists of the following messages:

CPC Request

CPC Response

CPC Call Terminations (optional)

Heartbeat (optional)

5

The following HTTP message flow encapsulates the CPC query/response messages:

Figure 2-2: HTTP Exchange

3.0          Network Architecture

Figure 3-1 below represents the network architecture to allow the CPC to pass client related information to the PS and receive routing information so that the call can be delivered to the PSAP.

The CPC may be a single call center or redundant, geographically distributed locations as shown in Figure 3-1. Normal operation would have a primary call processing center that would process calls and a secondary one that would be used for disaster recovery. The Position Server will always operate in a redundant, geographically distributed configuration. The mated pair will operate in primary/secondary configuration where the secondary Position Server may take over for the primary if the primary is removed from service.

In this configuration there is a logical link between each CPC and each PS. The network connection between the CPC and the PS is expected to be either a private packet-based network or a dedicated point-to-point environment.

6

Figure 3-1 Network Configuration

4.0          Session Establishment

For the GRIXE interface, the TCP/IP address and port are agreed upon between the owners of the CPC and the PS. By convention, the PS is the TCP/IP server and the CPC is the TCP/IP client. The sessions are established via sockets where the CPC establishes the connection to the PS. Upon system start up the PS will listen to the designated port, and the CPC will initiate session set up to the designated TCP/IP address and port. Once the socket session is established, the application may begin the query and response handshake.

5.0          Query Response Call Flows

When the CPC queries the PS, there are two call flows that can be expected. The first is where the PSAP is covered by this application and the call can be delivered as a native 9-1-1 call. In this scenario, the PS returns an Emergency Services Routing Number (ESRN) and an Emergency Services Query Key (ESQK). The ESRN identifies the terminating switch in the Emergency Services Network and is used by the CPC to route the call. The ESQK is a query key that is valid for the life of the call, is routed along with the ESRN through the network, and is used by the PSAP to query for a customer subscriber record. The second scenario is where the PSAP is not covered by this application and the call must be routed to the PSAP as an anonymous call. The PS returns the PSAP DN to the CPC and the CPC routes the call using the PSAP DN. In this case, there will not be any subscriber information available to the PSAP.

7

5.1          Calls Treated as Native 9-1-1 Calls

The flow illustrated in Figure 5-1 shows the scenario where the ESQK and ESRN are returned to the CPC. The CPC can then route the call through the Public Switched Telephone Number (PSTN) to the Emergency Services Network so it can be handled as a native 9-1-1 call.

Figure 5-1: Native 9-1-1 Call where ESQK and ESRN are returned to the CPC

1.            The CPC has received an emergency call and sends an XML query to the Position Server. At a minimum, Subscriber Telephone Number (Subscriber_TN), Provider ID (PROVIDER_ID), Date Stamp (ADS), and Time Stamp (ATS) are sent in the query. Additional information may also be passed.

2.            The Position Server retrieves the X/Y coordinates based on the Subscriber_TN and queries the Coordinate Routing Database (CRDB) with those coordinates.

3.            The CRDB returns the PSAP ID and PSAP DN of the PSAP that is serving the area of the caller.

4.            The Position Server uses the PSAP ID to determine the ESRN associated with the terminating switch in the Emergency Service Network and an ESQK that will be associated with this call. It returns these along with the Date Stamp (ADS) and Time Stamp (ATS) to the CPC.

8

5.            The CPC routes the call through the PSTN using the ESRN as the Called Party Number and the ESQK as the Calling Party Number.

The ESRN enables routing the call to the E9-1-1 Selective Router in the Emergency Service Network that is local to the caller and identifying the call as an emergency. Once the call has been identified as an emergency, normal 9-1-1 call processing takes over. The ESQK is then used as the caller’s Automatic Number Identification (ANI) for use in selectively routing the call to the correct PSAP and retrieving the caller’s Automatic Location Identification (ALI) record from the Position Server. The ALI record contains the caller’s real callback number and their location, i.e. postal address.

5.2          Calls Treated as Anonymous Calls

If the Emergency Services Network is not set up to handle CPC emergency calls across the PSTN, calls can still be delivered to the correct PSAP. This is done by routing the call to the 10-digit local exchange line terminating at the PSAP. Calls to these lines cannot be treated as native 9-1-1 calls. This means that the PSAP cannot query for information associated with the caller. This call flow is shown in Figure 5-2.

Figure 5-2: Calls Treated as Anonymous Calls

1.            The CPC has received an emergency call and sends an XML query to the Position Server. At a minimum, Subscriber_TN, Provider ID (PROVIDER_ID), Date Stamp (ADS) and Time Stamp (ATS) are sent in the query. Additional information may also be passed.

9

2.            The Position Server retrieves the X/Y coordinates based on the Subscriber_TN and queries the CRDB with those coordinates.

3.            The CRDB returns the PSAP ID and PSAP DN of the PSAP serving the area of the caller.

4.            The Position Server uses the PSAP ID to attempt to determine the ESRN and an ESQK but finds that this PSAP does not support CPC calls as native 9-1-1 calls. The PS returns the 10-digit local exchange DN to the PSAP along with the ADS and ATS to the CPC.

5.            The CPC routes the call through the PSTN using the PSAP DN as the Called Party Number. The call is then delivered to the PSAP local exchange line.

6.0          Call Processing Center Interface Messages

The GRIXE message set uses XML based application messages between the CPC and the PS. These message sets are defined in Appendix B; example messages are found in Appendix A. There are three types of messages: query/response, call termination, and Heartbeat. The query/response messages allow the CPC to query the PS and have the PS respond with routing numbers. The call termination message is an optional message from the CPC to the PS, which allows the PS to release transient call data upon completion of the call. The Heartbeat message allows a client to determine at regular intervals if the link and the PS application are still alive and functioning.

6.1          GRIXE Query/Response Messages

The CPC queries the PS for routing information. The CPC will query with a Call Processing Center Query (CPCQ) message with type=“Q”. The expected elements are Subscriber TN (key/Callback Number), ADS (Day), ATS (Time), Provider ID (PROVIDER_ID), and Service Provider Number (SPN). The format of the query is:

<CPCQ type=“Q” version=“1.0”>

elements

</CPCQ>

The expected elements are defined as:

ADS – The Date Stamp provides the UTC (Coordinated Universal Time) date when the query is made. Expressed in the format CCYYMMDD where CCYY is the four-digit year, MM is the month, and DD is the day of the month.

ATS – The Time Stamp provides the UTC time when the query is made. Expressed in military format HHMMSS where HH is hours, MM is minutes, and SS is seconds.

SPN – The Service Provider 7x24 number is expected and is required to be a full ten-digit North American Numbering Plan (NANP).

Subscriber_TN – The Subscriber TN element is the key component used to determine the emergency service network for the caller. Records for all subscribers are pre-provisioned in the PS. The records include the physical location of the subscriber. This is required to be a full 10-digit North American Numbering Plan (NANP).

10

PROVIDER_ID – The NENA Company ID of the CPC.

Optional elements:

POS – The position provides an identifier for the Call Processing Center. This could identify the CPC if there are multiple locations, or this could be an agent ID if the center supports attendants and desires to uniquely identify agents serving these calls.

Message_ID – The message identification field is used to correlate the query with the response. If this element is included in the CPCQ, the CPCR will include a Message ID element with the same integer value as it received. This element is useful when a persistent connection is supported by the CPC to keep track of outstanding responses. The field is defined to be an integer that supports up to 6 digits, value 0-999999.

The Position Server will respond with a CPCR message with the type=“R”. If the PSAP serving area is equipped to handle this native 9-1-1 application the expected response elements are ESRN, ESQK, STATUS(0), ADS, and ADT. If the PSAP serving area is not supported by this application, the Position Server will return the PSAPDN, STATUS(6), ADS, and ADT. If the Subscriber TN has not been provisioned on the PS, the Position Server will return STATUS(8), ADS, and ATS. For any other type of error condition, the STATUS element in the message, along with ADS and ATS, will be returned to explain the error condition. The format of the response is:

<CPCR type=“R” version=“1.0”>

elements

</CPCR>

The expected elements are:

ESQK – The ESQK is a unique key assigned from a pool of keys by the PS to the call for the duration of the call. It is passed through the network with the call set up and used by the PSAP to query for information related to this incident. (Required full ten-digit NANP format.)

ESRN – The ESRN designates the terminating switch in the Emergency Services Network. It is assigned by the PS and used by the CPC to route the call through the PSTN. (Required full 10-digit NANP format.)

PSAPDN – The PSAP DN is the 10-digit local exchange telephone number at the PSAP, which will route to an Intrado telecommunicator at the ECRC who will then transfer the call to the correct PSAP. This line does not have any Emergency Services functionality associated with it. (Required full 10-digit NANP format.)

STATUS – Denotes if the response is normal (successful) or contains error information.

ADS – The Date Stamp provides the UTC (Coordinated Universal Time) date when the query is made. Expressed in the format CCYYMMDD where CCYY is the four-digit year, MM is the month, and DD is the day of the month.

ATS – The Time Stamp provides the UTC time when the query is made. Expressed in military format HHMMSS where HH is hours, MM is minutes, and SS is seconds.

11

Optional element:

Message_ID – This element is included in the CPCR if the CPCQ contained one. The value included in the response will be the same integer value as received in the CPCQ/Message_ID.

STATUS type enumerations are:

0            Native 9-1-1 Delivery, Query Successful – Effect: ESRN and ESQK returned.

1            Resource Unavailable – Effect: Resource such as CRDB not available, no PSAP information returned.

2            Failed Parsing – Effect: Invalid XML structure or invalid data, no PSAP information returned.

3            Unauthorized Request – Effect: Query rejected.

4            Unrecognized Geodetic Information – Effect: No PSAP information can be returned.

5            Resource Exhaust – Effect: Possible error such as ESQK exhaust, PSAP DN will be returned.

6            PSAP DN Delivery – Effect: Return a PSAP DN (expected delivery for non-native 9-1-1 application).

7            General System Error – Effect: Unspecified system error, no PSAP information can be returned.

8            Subscriber TN not provisioned – Effect: No PSAP information can be returned.

6.2          GRIXE Call Termination Report (Optional)

A call termination report is sent from the CPC to the PS when the emergency call is terminated. This will allow the PS to release transient data, such as ESQKs, so they may be used for subsequent calls. The message only pertains to those calls where the CPCR included an ESQK and ESRN. It is not applicable when only the PSAP DN was provided. Some CPCs may not maintain the knowledge of the type of call in progress (for example, emergency) so this message is optional. Call Termination Report messages received by the Position Server for which no ESQK or ESRN were allocated will be ignored. A response to this message from the PS to the CPC is not required. This message is a CPCQ with type=“T”. The expected parameters are Provider (PROVIDER_ID & SPN), Subscriber_TN, ADS, and ATS. The format of the message is:

<CPCQ type=“T” version=“1.0”>

elements

</CPCQ>

6.3          GRIXE Heartbeat Report (Optional)

A Heartbeat messages can be sent by the CPC to verify the integrity of each logical link connection to the Position Server. These will be initiated by the CPC and responded to by the Position Server. The initiation of the Heartbeat message is denoted by a CPCQ message with the type of “H” and should only be sent during times of inactivity. The Position Server will respond to the Heartbeat message with a CPCR message with the type of “H”. The parameters ADS and ATS are expected in both the CPCQ and CPCR.

12

The CPC is expected to maintain the logic for determining corrective action to take if it does not receive a response from the PS. The format of the heartbeat query and response are as follows:

CPC to PS

<CPCQ type=“H” version=“1.0”>

elements

</CPCQ>

PS to CPC

<CPCR type=“H” version=“1.0”>

elements

</CPCR>

Introduction

1.1          Executive Summary

This document describes the acceptance end-to-end test plan for V911. Wide Area Network (WAN) functionality, Call Processing (for normal and fail-over scenarios) and Data File Management will be tested. Internal integrated test plans will be used to test internal processes and procedures in addition to this plan. There are four main features of this test.

1.            Network – Validation of WAN Infrastructure

2.            Call Processing – Automated – uses GRIXE/GRISIP, IPS and telecom infrastructure.

3.            Call Processing – Manual – uses the ECRC and telecom infrastructure

4.            VoIP Calling Number and Address Provisioning – Automated – uses the Intrado Validation and Update Interface, VUI

The test plan covers standard and non-standard queries and responses to achieve call completion for calls made over the VoIP network. Supplier’s tracking system will be used to log results. A regularly scheduled test meeting will be used to review the results and plan any re-testing required.

The test runs during a mutually agreed upon period. The test includes active participation by the Customer and Supplier. Post-document sign-off indicates the service is ready to launch.

1.2          Project Scope

This document covers the test approach, resources, specific functionality, schedule, assumptions, and risks of the testing activities that will be performed for this release.

1.5          Assumptions

•      The tests will require coordination between Supplier and CUSTOMER.

•      Provisioning will be tested via the Intrado VUI.

•      CUSTOMER will activate 9-1-1 calling for three (3) to four (4) of CUSTOMER’s subscribers.

•      Supplier will provide scripts for the callers during the ECRC tests.

2.0          Test Strategy

2.1          Approach

•      Development is being performed at Supplier and CUSTOMER’s facility.

•      There will only be one (1) milestone code drop when 100% of the code will be delivered for testing.

•      Testing will begin once the code is fully unit tested and delivered to CUSTOMER.

5

•      Supplier will provide a list of zip codes that are supported by three (3) to four (4) selected PSAPs.

2.2          Acceptance Test Techniques

The test effort consists of multiple end-to-end integrated tests to verify overall functionality. In addition, smaller functional tests are included to verify specific requirements. As testing progresses, existing tests may be modified or new tests written to explore as yet unseen areas of concern.

As areas of concern are encountered, members of the test team will mutually decide how to proceed as follows:

•      Note area of concern in comments area of test case and proceed with testing.

•      Contact development to share information and explore options.

•      Identify area of concern as a Defect and open a Change Request ticket. CUSTOMER to send email to Product Manager.

•      Identify area of concern as a future enhancement and open a CR ticket. CUSTOMER to send email to Product Manager.

•      Decide if testing can continue.

2.3          Test Documentation

•      This test plan will be added to Supplier’s Document Library once it is baselined.

•      Test Cases and Test Results will be stored and managed using this test plan. Results can be requested by any team member.

•      All Change Requests (“CR”) will be tracked using Supplier’s ticketing system. Project management has the ability to create reports containing any and all tickets generated during the test interval. Outstanding CRs will be discussed in the daily test meetings.

•      Test results and release notes will be published by the Supplier team lead and added to the Supplier Document Library at the end of the test interval.

•      Supplier and will sign-off that they are ready to launch. Each company will maintain a copy of the sign-off sheet.
