ISSUE TITLE:  Test Number Guidelines For Switches With End Office/Tandem
              Functionality

         ISSUE ORIGINATOR: George Stanek
                  ISSUE #: 0053

          ISSUE CHAMPIONS:

Is this an ESP Request (Y/N): N

ISSUE STATEMENT:

The Testline Guidelines Section of the Operations Reference Document
identifies trunk testing procedures between two tandem switches using 3
digit test numbers (and corresponding 7 digit test numbers), and between
tandem switches and end office switches using 7 digit (NPA specific) test
numbers.  More recently, some ASPs have deployed switches in their networks
with combined tandem / end office functionality.  ASCs would like to be
able to test the tandem to tandem portion of this network trunking
arrangement using the 3 digit test numbers.  However, since this is also an
end office some ASPs have only provided the 7 digit (NPA specific) test
capability to test the tandem to end office portion of the network trunking.

SUGGESTED RESOLUTION:

Recommend in the Testline Guidelines Section that ASPs deploying switches
with combined tandem / end office functionality should provide 3 digit test
capability to test the tandem to tandem trunking, as well as, 7 digit (NPA
specific) test capability to test the tandem to end office trunking
whenever technically feasible.

OTHER IMPACTS (if any):

NIIF Issue #0025 (formerly NOF Issue #260)

CURRENT ACTIVITY:

03/05/97

It was agreed to accept this issue for work by the NIMC.

04/28/97

Status: Active

Action Items:

ASP participants are to report back and discuss their 3 and 7 digit
testline capability for combined tandem/end-offices.  George Stanek, AT&T,
will draft language for inclusion in the guidelines related to this issue.

Agreement Reached:

It was agreed that IXCs will be asked about the possibility of reciprocal
3 and 7 digit testing capabilities under new business at NIMC #4.

06/26/97

Status: Active

Action Item:

NIMC participants are to review the proposed resolution to Issue #53 as
follows:

3.0     Testline Access

3.1     It is recommended that all interconnected service providers (ASPs
        and ASCs) should provide testline access to their end office and/or
        tandem switches.

        Testline access to end office switches should be provided
        utilizing a seven (7) digit test number format (i.e., NXX-XXXX).

        Testline access to tandem switches and combination end office/
        tandem switches should be provided utilizing:

     ** a three (3) digit test number (i.e., XXX) as the primary test number
        format

     ** a seven (7) digit test number (i.e., 958-XXXX) as a secondary test
        number format

     ** a seven (7) digit test number (i.e., 959-XXXX) as a secondary test
        number format for embedded AT&T testline access

08/21/97

Status: Initial Closure

NIMC participants are to review the proposed resolution to Issue #53 as
follows:

3.0     Testline Access

3.1     It is recommended that all interconnected service providers should
        provide testline access to their end office switches, tandem
        switches and combination end office/tandem switches.

        Testline access to end office switches should be provided utilizing
        a seven (7) digit test number format (i.e., NXX-XXXX).

        Testline access to tandem switches or to the tandem function of the
        combination end office/tandem switches should be provided
        utilizing:

     ** a three (3) digit test number (i.e., XXX) as the primary test number
        format

     ** a seven (7) digit test number (i.e., 958-XXXX) as a secondary test
        number format

     ** a seven (7) digit test number (i.e., 959-XXXX) as a secondary test
        number format for embedded AT&T testline access

25.     Participants agreed to move Issue #0053: Test Number Guidelines for
        Switches with End Office/Tandem Functionality, to initial closure.

10/22/97

Status: Final Closure

Agreement Reached:

Participants agreed to move Issue #0053 to Final Closure.

RESOLUTION:

The following text was agreed to by the NIIF and will be included in the
NIIF Operations Document (Part V, Testline Guidelines & Coordinator's
Directory) as the resolution to this issue:

3.0     Testline Access

3.1     It is recommended that all interconnected service providers should
        provide testline access to their end office switches, tandem
        switches and combination end office/tandem switches.

        Testline access to end office switches should be provided utilizing
        a seven (7) digit test number format (i.e., NXX-XXXX).

        Testline access to tandem switches or to the tandem function of the
        combination end office/tandem switches should be provided utilizing:

     ** a three (3) digit test number (i.e., XXX) as the primary test number
        format
     ** a seven (7) digit test number (i.e., 958-XXXX) as a secondary test
        number format
     ** a seven (7) digit test number (i.e., 959-XXXX) as a secondary test
        number format for embedded AT&T testline access
