MMC 414:
MPD/PRS Signal
DESCRIPTION:
MMC 414 allows MPD(Meter Pulse Detection) or PRS (Polarity Reversal Signal) to be assigned to Trunks on
a Trunk by Trunk basis. MPD or PRS Hybrids must be installed in each Trunk circuit programmed for
MPD/PRS in MMC 414.
MPD Hybrids provide 12 kHz meter pulse detection. The meter pulses are sent from the network and must be
requested from the Carrier.
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 stopped. Not used in Australia.
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)
.
NOTE: PRS Reversal on Answer (ROA) is only supported by the DCS V5.X software. The DCS 70,
DCS24 and DX408 systems support PRS ROI only.
