Procedure 11.4: OSPS INTERFLOW MAINTENANCE B-CHANNEL LOOPBACK TEST
OVERVIEW
This procedure provides for B-channel loopback testing between two integrated services digital network (ISDN)
switching modules (SMs). This test is part of the Operator Services Position System (OSPS) interflow maintenance
capability. B-channel loopback tests are the only craft-initiated test logic provided by this capability.
Performing B-channel path verification and performance tests shall be allowed under two configurable test
approaches: interactive digital testing (IDT) and automatic digital testing (ADT). Each of these test approaches will
implement a loopback test from switch to switch. The IDT and ADT will be allowed to originate from OSPS-a only.
The operator trouble reports (OTRs) will provide the trunk group and member number of the extended digital
subscriber line (EDSL) involved in a call in addition to the usual information.
NOTE:
It is required that a B-channel path verification test leave the status of the B-channels under test as they are
encountered. In other words, if the trunk is in-service when the test begins, it will be restored to in-service
when the test is complete. If the trunk is out-of-service (OOS) when the test begins, it will be left OOS at
the end of the test.
PROCEDURE
1.
There are two B-channel test procedures which may be performed:
IDT may be performed by doing Steps 2 through 6.
ADT may be performed by doing Steps 7 through 10.
2.
At the trunk and line work station (TLWS) video terminal, if (assigned) test position is not currently accessed,
access it by entering the TLWS poke command (CMD)
16x
. A message will be generated on the receive-only
printer (ROP) indicating that a position has been seized.
3.
From screen 4000,2 enter either poke CMD
4102
or
4104
to seize control of an OSPS-EDSL B-channel. A
message will be printed on the screen indicating that the trunk has been seized.
4.
From screen 5000,2 enter poke CMD
5033
to request an interactive loopback test on the selected
B-channel(s). Results will be displayed on the TLWS screen as per normal interactive loopback testing.
5.
When the test is completed, either terminate the test by entering the input message
STP:TST
or entering the
poke CMD
5999
.
6.
If no further testing is needed on the trunk, release the trunk by entering the poke CMD
4999
.
STOP. YOU HAVE COMPLETED THE IDT PORTION OF THIS PROCEDURE.
7.
At the TLWS video terminal, if (assigned) test position is not currently accessed, access it by entering the
TLWS poke CMD
16x
. A message will be generated on the ROP indicating that a position has been seized.
8.
From screen 4000,2 enter either poke CMD
4102
or
4104
to seize control of an OSPS-EDSL B-channel. A
message will be printed on the screen indicating that the trunk has been seized.
9.
From screen 5400,1 request an automatic loopback test on a B-channel which is traffic busy using poke CMD
5405
,
5406
, or
5407
. This test will run for a specified duration and print results on the ROP.
