■ EPF/PTC Inquiry Test — For a TN413 or 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.
