[414] MPD/PRS SIGNAL
Used on a per-trunk basis to define if a Trunk line is to be either a Metering Pulse Detec-
tion (MPD) or a Polarity Reversal Signal (PRS) trunk.
An MPD Trunk will detect a C.O-provided meter pulse. A Polarity Reversal trunk will de-
tect 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.
