5.2.2 Modem Unit Installation
Before installing the MPB, if required, the optional Modem Unit (MODU) must be installed. The
MODU is an analog modem supporting Bell, ITU-T, V.34, V.32BIS, V.90 Protocol at a baud rate of
300bps to 33Kbps with automatic rate negotiation. The MODU provides a modem for connection to
the system database and maintenance functions. The MODU can be accessed remotely over an
analog CO line by calling the Modem CO line or Station. For additional information on MODU set-up,
see the iPECS-MG Admin Manual.
The MODU is installed on connectors CN4 and CN5 of the MPB as shown in Figure 5.2-1. Use care
to align pins of the CN4 and CN 5 connector with the CN1 and CN2 connectors on the MODU and
press firmly in place.
5.2.3 MPB Installation
Before installing the MPB, mount the optional MODU as described above. The MPB must be
installed in the MPB slot, the upper left slot of the BKSU.
Assure Power is OFF
Slide the MPB in the guide rails of the first slot (upper left) of the Basic KSU.
Tighten thumbscrews to hold the board firmly in place.
