Digital Station Audits Test (#17)
This is a series of six tests which are classified as audits. The SPE 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 SPE records according
to the circuit pack’s records. This inquiry is sent all the way to the voice
terminal.
■ Bad Scan Inquiry Test — A message is sent uplink which contains a count
that is generated due to certain events relating to the link conditions. This
can be an indication of communications problems between the Processor
and Digital Port circuit pack.
■ EPF/PTC Inquiry Test — For a TN754 vintage 13 or earlier, the status of the
Electronic Power Feed (EPF) is sent uplink. Possible conditions are:
EPF-on-ok, EPF-off, and EPF-no-load. For TN754 vintage 14 or later,
TN754B or TN2136, TN2181, TN2224, the status of the Positive
Temperature Coefficient (PTC) is sent uplink. Possible conditions are:
PTC-on-ok, PTC-off, and PTC-no-load .
■ 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 which 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.
PASS The message to light all of the station lamps was sent successfully to the
port.
1. Observe the station lamps being lit when running the test. If all lamps
do not light successfully, the other Digital Line test results may indicate
related problems that will not allow the lamps to light.
2. Investigate by using other Digital Line port tests, and by examining the
station, wiring, and connections.
