[420] PRS SIGNAL
Used on a per-trunk basis to define if a Trunk line is to be either a Metering Pulse(MPD) or
a Polarity Reversal Signal(PRS) trunk.
A Meter Pulse Trunk will detect a C.O provided meter pulse. A Polarity Reversal trunk will
detect the line reversal signal which may be provided by the Trunk Line When the other
party answers the outgoing call or the outside party clears the call.
There are three types of PRS mode: PRS 1, PRS 2 and PRS 3.
Type
Description
PRS 1
When first PRS is detected, call duration is started. When second PRS is detected,
call duration timer stopped. The call is not released until hanging-on.
PRS 2
When first PRS is detected, call duration timer is started. When second PRS is
detected, call duration timer is stopped and call is released.
PRS 3
The call duration timer starts based on the timer. When first PRS is detected, call
duration timer is stopped and call is released.
