24 Chapter 1 Introducing the Business Communications Manager

—Two DS30 buses are exclusively dedicated to MSC resources. Five paths within these buses have hard-coded applications. The other paths can be assigned to various applications such as voice mail, dialup ISDN WAN, VoIP trunks, or IP telephony.

—Five DS30 buses are exclusively reserved for the media bay modules

—The sixth DS30 bus can be switched to accommodate media bay modules or more channels for IP telephones or VoIP trunks. You control the use of the bus by your choice of using either a 2/6 or 3/5 DS30 split. This is set when you run the Quick Start Wizard at the initial startup of the system.

For more details about deciding which DS30 split configuration you want for your system, refer to “Determining module DS30 bus requirements” on page 64 and to the chapter on configuring MSC Resources in the Business Communications Manager Programming Operations Guide.

•PEC IIIs — The BCM1000 uses PEC IIIs to deliver increased capacity for digital signal processing for voice mail, call center, FAX, VoIP trunks, IP telephony, and dialup ISDN WAN. The basic system comes with two PEC IIIs. Two more can be added to accommodate increased requirements for media processing. Refer to the chapter on configuring MSC Resources in the Business Communications Manager Programming Operations Guide.

Connection ports

You can connect to the BCM1000 through your computer via the serial port or a LAN card connection to perform setup and maintenance procedures. Refer to Figure 7. This guide leads you through the process of making either of these connections. Refer to “Using a null modem serial cable” on page 125 and “Connecting the Ethernet crossover cable” on page 129.

Programming procedures using the Unified Manager, are explained in the Programming Operations Guide.

Serial port LAN

Note: On some new systems, the serial and video ports are swapped. The serial cable connector will only fit on the correct port.
