detects activity and determines that the signal is valid (or the Tx key line is
activated), it reverts to Normal mode. Otherwise, the timer continues
running.
When the timer reaches the value for Deep Sleep mode, the base station
enters Deep Sleep mode.
If the base station is running on AC power, the timer operates as usual.
However, the base station will continue to run in Normal mode, as
configured in the Service Kit, even after reaching the value for Sleep or
Deep Sleep mode. It only enters these modes after it has changed over to
DC power. If it changes back to AC power, it returns to Normal mode.

The following tables show the receiver cycling times and Tx keyup times
