Description
by the MMB-1/-2 or the PSR-1,
depending on the application. The
network control signals are distributed
to the plug-in boards through the
OMM-1. All connecting cables are
supplied with the unit.
Up to three OMMs or MOMs fit into a
single MME-3 enclosure. No more
than three OMMs can be connected
together, or, when a TSP-40 printer is
used, no more than two OMMs or
MOMs can be connected.
OMM-2 Output Master Module
The OMM-2 is the card cage for any
two half-width (OCC-1, ASC-1/-2,
ZAC-30, DMC-1, PLC-4 or ZC zone
cards) or one full-width (RCM-1) MXLV
plug-in boards. The module has the
same dimensions as the MOM-2 MXL
card cage. The OMM-2 mounts verti-
cally in the MME-3 enclosure.
Voice system field wiring terminates
on the OMM-2 terminal blocks. Power
and network communications are
provided by the MMB-1/-2 or the
PSR-1, depending on the application.
The network control signals are distrib-
uted to the plug-in cards through the
OMM-2. All connecting cables are
supplied with the unit.
The MME-3 Voice System enclosure
has three locations for the OMM-2 (or
for OMM-1s, MOM-4s or MOM-2s).
However, when a TSP-40 printer is
installed in a system, it decreases the
number of OMMs (or MOMs) to two
modules a system.
