414 PRS Signal

Used on a per-trunk basis to define if a Trunk line is to be either a Metering Pulse

Detection(MPD) or a Polarity Reversal Signal(PRS) trunk.

A Metering Pulse Trunk will detect a C.O provided metering 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.

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 : PRS 1, PRS 2 and PRS 3.

PRS Mode 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.
