3.15.1. Ringtrip Timeout Counter
The Dual ProSLIC incorporates a ringtrip timeout
counter, RTCOUNT, that will monitor the status of the
ringing control. When exiting ringing, the Dual ProSLIC
will allow the ringtrip timeout counter a sufficient amount
of time (RTCOUNT x 1.25 ms/LSB) for the mode to
switch to On-hook Transmission or Active. The mode
that is being exited to is governed by whether the
command to exit ringing is a ringing active timer
expiration (on-hook transmission) or ringtrip/manual

mode change (active mode). The ringtrip timeout
counter ensures ringing is exited within its time setting
(RTCOUNT x 1.25 ms/LSB, typically 200 ms).
3.15.2. Ringtrip Debounce Interval
The ac and dc ring trip debounce intervals can be
calculated based on the following equations:
RTACDB = t
RTDCDB = t
