General Description
The AUTOMATIC TRUNK TEST capability provides a functional test on a large number of trunks at a
prearranged time. The results of the test are reported at the MAINTENANCE ADMINISTRATION
TERMINAL (MAT) [M-18]. The test can include: Ringback Tone Test, 1 KHz Test Tone and Trunk
Selection Test, by having the proper test trunk termination at the distant office.
Operating Procedure
To activate the AUTOMATIC TRUNK TEST, input the route and trunk number to be tested by using the
TTLC command:
1.
Input the TTLC and ATTD command.
2.
The system will prompt for either Immediate or Scheduled Execution of the AUTOMATIC
TRUNK TEST feature. If Scheduled execution is chosen, the time when the test begins is
entered via the MAT.
3.
The system will ask for the route number to be tested as "RT" on CRT.
4.
Input a route number from 1 ~ 255.
5.
The system will ask for the trunk number(s) to be tested as "TK" on CRT.
6.
Input the trunk number from 1 through 255. Input the trunk number(s) to be tested as the test
goes from "TRK NUMBER" to "TRK NUMBER".
7.
The system will execute the trunk test based on the data input above. Test results will be printed
out after all trunks have been tested.
Service Conditions
1.
Additional hardware required consists of one LTST (PH-M16) card, one 8TLT card, and one line
circuit and LTST cable.
2.
Trunks are tested in conjunction with the connecting office through the selected trunk, on a one-
at-a-time basis. The following different trunk functions can be tested on all trunks in a specified
group:
a.) trunk selection,
b.) detection of Ringback Tone sent back from the connecting office after test number
outpulsing,
c.) detection of test tone (1 KHz) returned from AUTOMATIC TRUNK TEST facility if
provided at the connecting office.
3.
As part of the AUTOMATIC TRUNK TEST facility, an AUTOMATIC TRUNK TEST is provided at
the NEAX2400 ICS to answer incoming test calls. Upon terminating the incoming test call from
the originating office through a selected test trunk, the AUTOMATIC TRUNK TEST generates a
1 kHz tone to the originating office as an acknowledgment signal.
4.
If scheduled execution is chosen, the time when the test begins is entered via the MAT. The MAT
is dedicated to the AUTOMATIC TRUNK TEST function from the time the test is ordered until
the completion of the test.
