these individual cards have been eliminated. The WAN card is now field installable, meaning that
the base platform has been simplified and only those customers needing the WAN interface have
it in the system.
Release 3.0 also incorporates a number of “Design for Serviceability” aspects that make the BCM
easier to install, support and service. The improvements, including the hardware design with slide
out front-accessible shelves, the field replaceable Media Services Card (MSC) and the provision
of both a standard and a full redundancy version of the base system, have been designed to
contribute to ROI. The upgrade from Release 2.5 or FP 1 to release 3.0 has been redesigned to
reduce the time it takes to complete an upgrade while making the upgrade procedure easier and
more robust. In addition, its design will facilitate easier upgrades to future releases of the BCM,
making installed base support and migration an opportunity for ROI contribution.
Business Communications Manager Components
Connection Ports
Serial Port
The BCM is equipped with one serial port that supports asynchronous serial data communication.
The port has a male DB-9 connector and supports all standard baud rates (9600 default).
The serial port connects serial devices, such as a laptop computer. An engineer uses this port to
set the initial IP address on the BCM before connection to the customer’s LAN.
A null cable is required for this connection. Alternately, a crossover Ethernet cable can be
connected directly between a Network Interface Card on the BCM and a Network Interface Card
on a laptop. The other ports include a USB port, modem and serial connection point.
