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 web admin or 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 eMG800 Administration & Programming
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.
