Purpose
: Used on a per-trunk basis to define if a C.O. line is to be either a Metering
Pulse Detection (MPD) or a Polarity Reversal Signal (PRS) trunk. (PRS is not available
in the UK.)
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 desig-
nated 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 conversa-
tion which is unsupervised by an internal party.
