3. Port Diagnostic Test—the battery feed circuitry is tested for hook
detection.
4. Port Audit Update Test—updates the DID translation information on
individual ports of the DID trunk. The port translation data consists of
signaling parameters whose values depend on the CO switch connected
to the trunk. These parameters include:
■ wink (signal indicating PBX is ready to receive digits) or immediate
start
■ dial tone or rotary dialing trunk
■ rotary dialing inter-digit timing
■ network balance R/RC
■ disconnect timing
Additional in-line testing is performed while a call is in progress. Thus, in-line
errors may occur during operation. See Error Log table for a description of these
errors. These errors may be reproduced by using the trunk (that is, placing a call)
and checking their occurrence in the Hardware Error Log.
Problems detected during signaling may be caused by faults off-board (in the
CO switch or connections) for which a Warning alarm is raised.
Before a maintenance test can be run on a port, the port must be idle. If an
incoming call seizes the port which is being tested by maintenance, the test is
aborted, and the incoming call proceeds.
For transmission and signaling standard specification, refer to Digital PBX
Standards document RS4648.
