Avaya 03-300430 User Manual

This is a series of six tests that are classified as audits. The media server sends messages to 
the on-board microprocessor to perform the following tests. These audits run only if the station 
is in-service.

●

Switchhook Inquiry test 

— 

This is an update of the media server’s records according to the 

circuit pack’s or media module’s records. This inquiry is sent all the way to the voice 
terminal.

●

Bad Scan Inquiry test 

— 

An up-link message is sent containing a count generated by 

certain events relating to the link’s conditions. This can be an indication of communications 
problems between the media server and Digital Port circuit pack or media module.

●

ID Request test 

— 

A request is made to the station for its status. The station sends its 

configuration information and health information back. This information is checked and a 
pass/fail result is provided.

●

Ringer Update test 

— 

This updates the digital telephone ringer state according to the 

processor records.

●

DTMF Administration Update test 

— 

This is a message to the digital station to refresh the 

default value that causes the station to send touch- tones only in the primary information 
channel. This value is set initially when the station is put in-service and every time the 
station’s state changes from other states to in-service state.

●

EPF/PTC Inquiry test 

— 

For a TN413 or a TN754 (vintage 13 or earlier), an up-link status 

message of the Electronic Power Feed (EPF) is sent. Possible conditions are: EPF-on-ok, 
EPF-off, and EPF-no-load.

For TN754 (vintage 14 or later), TN754B, TN2136, TN2181, or TN2224, an up-link status of 
the PTC is sent. Possible conditions are: PTC-on-ok, PTC-off, and PTC-no- load.

PASS

The message to light every station lamp was sent successfully to the port.

1. Observe the station lamps being lit when running the test. If all lamps 

do not light, the other Digital Line test results may indicate related 
problems that do not allow the lamps to light.

2. Investigate by using other Digital Line port tests, and by examining the 

station, wiring, and connections.
