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.

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 IMX 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.
