25、interconnection testing for local number portability to ensure that all areas of network integrity and customer service from an interconnection perspective are addressed proactively. This document does not replace or supersede any existing contracts, tariffs or any other legally binding document. 1.

26、2 Definitions In general, the definitions for terms utilized within this document can be found in the Glossary section of the Network Interconnection Interoperability Forum (NGIIF) documentation. Any terms that are unique to this document are listed below, and will be included in the glossary. Defau

27、lt Routing: Default Routing occurs when the switch that normally performs the LRN Database query is unable to communicate with the SCP and the call is routed to the donor switch that performs the query and completes the call. Local Number Portability: The end-users ability to retain their telephone

28、number when moving to a different serving switch (Class 5). Location Routing Number: A 10-digit number used to uniquely identify a switch that is LNP capable. Donor Switch: The switch (Class 5) from where a number has been ported. Recipient Switch: The switch (Class 5) to where a number has been por

29、ted. NXX Opened to Portability: An NXX where numbers can be moved from a Donor Switch to a Recipient Switch. Ported (Number): A number that has been moved to a recipient switch. Non-Ported (Number): A number that has not been moved from a Class 5 switch. 2 Basic Premises In order for Local Number Po

30、rtability to be successful in terms of ensuring the integrity of Customer Service the industry needs to have in place an industry wide set of interconnection tests. Quality of Customer Service is predicated on all network providers being responsible for the assurance of the integrity of their respec

31、tive networks. A nationally agreed to Local Number Portability Interconnection test document will provide the appropriate direction to all network providers for the quality and integrity of interconnection. Information to be included in this document is a result of NGIIF agreements and pertains to i

32、nterconnection negotiations between network providers. 6 3 Operating Principles It is expected that all network providers have performed their respective internal network testing prior to interconnection testing taking place. It is expected that all problems/troubles identified during internal netwo

33、rk testing will be resolved prior to interconnection testing. Prior to interconnection for Local Number Portability (LNP), it is expected that all network providers have performed their basic SS7 internal and interconnection testing. It is expected that network providers have Number Portability Admi

34、nistration Center (NPAC) certification prior to network interconnection testing. 4 Scope of this Document This document is limited to LNP interconnection tests that are recommended to be performed by network providers (i.e. Cause Code 26N Validation Tests, Call Through Tests and Default Routing Test

35、s). The purpose of these tests is to provide assurance for the integrity of the interconnected networks. 5 Network Providers Responsibilities This section covers the responsibilities of network providers as it pertains to Local number Portability interconnection testing. Network providers are respon

36、sible to perform all necessary internal testing to ensure compatibility and compliance to standards and industry agreements for interconnection and network integrity. Prior to the commencement of Intra-LATA and Inter-LATA testing, ported or non-ported test numbers will need to be exchanged in order

37、to terminate test calls. When testing has been completed and the expected test results have been achieved, then the test numbers shall be returned. The network providers should work cooperatively to resolve network interconnection problems. Network providers should be familiar with the appropriate N

43、s/cooperation between interconnected parties. The testing of vertical features should be performed prior to interconnection of network providers. 8 Signaling System 7 Interconnection Testing (CCS 7) Signaling System 7, also known as SS7 or CCS 7 tests for interconnection are outlined in the NGIIF Do

44、cument under SS7 Trunks and Links, Part III. For the purpose of Local Number Portability it is recommended that all appropriate SS7 interconnection tests be performed prior to the commencement of LNP Interconnection testing. 9 Services Testing Service tests (e.g., E9-1-1, 611, and toll free services

45、) are considered to be stand alone tests and are to be performed by each network provider and do not require interactions/cooperation between interconnected parties. All services should be tested prior to interconnection for Local Number Portability. 8 10 Test Number Guidelines The Company with the

46、donor switch should exchange with the Company with the recipient switch, test number(s) associated with the NXX that has been opened for portability. All test numbers will be provisioned as working numbers (i.e., billable). Test numbers will only be assigned for the duration of the testing window as

47、 negotiated by the interconnecting companies. On completion of the LNP Interconnection Testing, the test number(s) will be disconnected and returned to the company with the donor switch immediately. In the event that a test number is not returned, the company with the donor switch can disconnect the

48、 assigned test number. Test number termination treatment should be negotiated by the interconnecting companies. 11 Interconnection Test Calls This section outlines the test calls that should be performed for interconnection. The interconnection test calls are categorized as follows: 11.1 Cause Code

49、26N Validation Tests 11.1.1 Test Number 1 - Intra-LATA Local via direct Trunks for Cause Code 26N Validation (Ported Number to Ported Number) 11.1.1.1 Test Description This will test that Cause Code 26N is returned on a local call via Direct Trunks when the called ported number is in the SCP (LSP-X), but has not been translated at the terminating switch (LSP-Y). (See Figure 1) Cause Code 26: This Cause Code indicates that the called party can not be reached because the “ported number” in the GAP identifies a called party that is not s
