A-96 Automatic Trunk Test - PRI
General Description
The AUTOMATIC TRUNK TEST capability provides a functional test on a large number of ISDN 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 Tone Test and Trunk Selection Test, by having the
proper test trunk termination at the distant office.
Operating Procedure
1. Input the TTLC command.
2. The system prompts 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 asks for the Route Number to be tested as RT on monitor.
4. Input a route number from 1 through 255. The maximum number of routes is 255.
5. The system asks for the trunk number(s) to be tested as TK on monitor.
6. Input the trunk number from 1 through 255. Input the trunk number(s) to be tested as test start 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. One LTST (PH-M23) card is required as additional hardware.
2. Trunks are tested in conjunction with the connecting office through the selected trunk, on a one at a time
basis. The following 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 Answer Trunk facility, if provided.
3. As part of the AUTOMATIC TRUNK TEST facility, an Automatic Answer Trunk (AAT) is provided at
the NEAX2400 IPX to answer incoming test calls. Upon terminating the incoming test call from the
originating office through a selected test trunk, the AAT generates a 1 kHz tone to the originating office
as an acknowledgment signal.
4. When activating this feature via the MAT, the system will prompt for either Immediate or Scheduled
Execution of the AUTOMATIC TRUNK TEST. If Scheduled Execution is chosen, the time when the test
begins is entered via the MAT. From the time the test is ordered until the completion of the test, the MAT
is dedicated to the AUTOMATIC TRUNK TEST function.
5. INDIVIDUAL TRUNK ACCESS [I-4] must be available when activating this feature.
6. Trunk test data must be assigned by ATTD command.
7. This service is available to trunks that can receive Push Button (PB) signals.
