24、nating Test Line Access and Capabilities. This Standard contains further information and descriptions of test lines. 2 Test Line Access Access Service Customers (ASCs) will be provided access to Access Service Provider (ASP) terminating test lines in the End Offices and in the Access Tandems. ASPs s

25、hould be provided with access to ASC terminating test lines. The following test lines, where applicable, should be provided and their access numbers exchanged by the ASCs and ASPs: 100 Type Test Line 101 Type Test Line 102 Type Test Line 103 Type Test Line 104 Type Test Line Non-Synchronous Test Lin

26、e Synchronous Test Line 105 Type Test Line 107 Type Test Line 108 Type Test Line 109 Type Test Line Short Circuit Open Circuit Analog Loop Around Test Lines. The following test line numbers are recommended to be used for ASP trunk side access to ASC test lines. Information on ASC/ASP test line acces

27、s can be obtained from each companys Test Line Coordinator. Company contact information can be found in the NGIIF Service Provider Contact Directory.1 The recommended outpulsing and numbering for ASC test lines is as follows: TEST LINE 7 DIGIT TEST LINE ACCESS 100 TL KP - 958-1100 - ST 101 TL KP - 9

Wh

32、en testing trunks terminating into end offices with local and tandem capabilities, verification of the proper switch pad must be taken into account. Testing of switch pad operation may be done in two manners: The ASP will (through manual or software control) operate the switch pad for proper configu

33、ration (local/tandem). The ASP will make available the test line numbers for tandem and/or local operation, so the ASC can verify the proper designed loss of the trunk. When ASP switching machines detect a Machine Detected Interoffice Irregularity (MDII) on ASP-ASC FGD service, test line number acce

34、ss is required for efficient and economical circuit isolation and repair. With the installation of such test access, MDIIs may be tested from the originating switch location without assistance from the terminating switch location. 3 Lineside (Call-through/Routing Testing/Service Provider Verificatio

35、n) 3.1 Service Provider Verification When it is necessary for an ASP to perform a SP verification, the recommended internal only numbers to use to make the verification calls are 700-555-4141 for interLATA pre-subscription validation or (HNPA) 700-4141 for intraLATA toll pre-subscription validation

36、and (101XXXX) 1-700-555-4141 for alternate carrier validation. These internal only calls will verify access to the current service provider and will not result in end-user billing. 3.2 Call-Through/Routing Testing To facilitate call-through tests, the Automatic Number Identification (ANI) of the lin

37、e to be used in making the test call may be needed to verify routing, if requested by the ASC. ANI should be provided by the ASP, prior to the call-through test via local agreements. ASC response to a call-through test should contain the ASC name and should be a “Barge in“ type of announcement. 4 Te

38、sting Through an Access Tandem Testing from an End Office through an Access Tandem to an ASC may be impossible due to Access Tandem test line number screening. It is recommended that the ASCs provide access to terminating test lines via the 700 Service Access Code (SAC), where available e.g., (101XX

39、XX) 1-700-958-1102 or (101XXXX) 1-700-959-1020. 5 9YY NXX, NPA/NXX, Toll Free, and International Call-Through Testing 5.1 Testing NPA/NXX or NPA/NXX-X NOTE: Additional information related to all other aspects of NPX-NXX Code Opening can be found in ATIS-0300032, Part X, Interconnection Between LECS

40、Operations Handbook Local Interconnection Service Arrangement and ATIS-0300010, NGIIF 4 Reference Document: Part 11, Installation and Maintenance Responsibilities Switched Access Services Feature Group B, C, and D. 5.1.1 New NPA/NXX The company opening a new NXX shall establish a working test number

41、 for call through purposes. The test number shall be established for a minimum period of 180 days. 5.1.2 New NPA/NXX-X in Thousands Block Pooling Situations The above testing rules also apply for a Code Holder opening an NPA/NXX-X block for the first time in a new NPA/NXX. NPA/NXX-X Code reallocatio

42、ns occur after a code has already been opened and established, generally have viable working numbers at the time of reallocation and would not typically require retesting. 5.1.3 NXXs Affected by NPA Relief Activity The company moving an NXX or NXX-X to another or a new NPA or rehoming an NXX or NXX-

43、X, shall have a test number established for the purpose of translation and billing validation call through testing. The test number shall be established for a minimum period of 180 days. Where possible the preferred termination for these test numbers shall be a recorded announcement that identifies

44、the terminating NPA/NXX or NPA/NXX-X. 5.2 Testing NPA/NXX All communications companies (wireline, cable, VoIP, wireless etc.) applying to the NANPA administrator and receiving a new NPA/NXX or Thousands Block(s) are expected to follow testing procedures as Code Holder. 5.2.1 New NPA/NXX The company

45、opening a new NXX shall establish a working test number for call through purposes. The test number shall be established for a minimum period of 180 days. 5.2.2 NXXs Affected by NPA Relief Activity, Switch Change, SwitchHoming Arrangements The company moving an NXX to another or a new NPA or rehoming

46、 (migrating, transferring or moving) an NXX to a different switch or a switch rehome to a different tandem shall have a test number established for the purpose of translation and billing validation call through testing. The test number shall be established for a minimum period of 180 days. 5.2.3 Mig

47、ration of NXX Code(s) Code migration is transferring a code from one switch to another and/or from one OCN to another and/or one service provider to another and should be a coordinated project. Testing and testing timeframes would be determined by the interconnected project partners and does not nee

48、d industry testing participation. A test line number should be published in the LERG Routing Guide for any company choosing to participate in testing NXX migration scenarios may include, but are not limited to, the following: Migrating all NXX codes from a switch to another switch/same or different

49、tandem Migrating one or more but not all NXX codes from a switch to another switch (OCN of the switch may or may not stay the same) 5 Type 1 to Type 2 wireless code migration (OCN of the switch changes). When the “A” record is moving from one switch to another switch, then the test number and test response field on the NXD screen should be populated with the appropriate test number and test response. 5.2.4 Changing a Tandem Association with an End Office Switch For tandem rehome activity the test number shall remain in effec
