— 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 

 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.

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 

. This guide leads you 

through the process of making either of these connections. Refer to 

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