How to determine if
a call is dropped
There are several methods for using the Test Set to determine if a call has been
dropped. Any of the following situations may occur.
Connect state ends
If the Connect annunciator goes off, and the Test Set returns to the Active state,
the call has dropped or ended.
DTC is not detected
If communication fails on the Reverse DTC, a message will appear at the top of
the screen: “No Reverse DTC is being detected, loss of Traffic Channel.” The Test
Set will return to Active state.
Analog connection ends
If communication fails on the AVC, a message will appear at the top of the screen:
“RF Power Loss indicates loss of Voice Channel.” The Test Set will return to
Active state. If the
Display field is set to Meas, the message “Analyzer is
underdriven. Increase signal level or gain.” is displayed.
