MPD/PRS SIGNAL
DESCRIPTION:
Used on a per-trunk basis to define if a C.O. 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 C.O. when the other party
answers the outgoing call or the outside party clears the call. If the trunk is designated as PRS
detection, the call duration timer will be started and the results printed on the SMDR record.
PRS detection is also essential for dropping a trunk-to-trunk conversation which is
unsupervised by an internal party.
There are three types of PRS mode: PRS1, PRS2 and PRS3.
PRS1:When first PRS is detected, call duration timer is started.
When second PRS is detected, call duration timer is stopped.
The call is not released until hanging on.
PRS2:When first PRS is detected, call duration timer is started.
When second PRS is detected, call duration timer is stopped
and call is released. (ROA type in Australia)
PRS3:The call duration timer starts base on the timer.
When first PRS is detected, call duration timer is stopped
and call is released. (ROI type in Australia)
