Installation and Maintenance Guide
IP Routing — Business Communications Manager software supports the following IP routing 
protocols: 
— static routing
— RIP (Routing Information Protocol)
— OSPF (Open Shortest Path First) 
NAT (Network Address Translation) — Business Communications Manager supports both 
static and dynamic NAT for a number of packet types and protocols. NAT is a network 
security feature that translates the IP addresses used within your private network to different IP 
addresses known to internet users outside your private network. 
Policy Management — Business Communications Manager allows you to implement classes 
of service and assign priority levels to different types of traffic using the DiffServ network 
architecture. You can configure policies that monitor the characteristics of traffic, for example, 
its source, destination, and protocol, and perform a controlling action on the traffic when 
certain user-defined characteristics are matched.
VPN (Virtual Private Networks) — Business Communications Manager uses the PPTP 
(point to point tunneling protocol) and IPSec (IP security) tunneling protocols to create secure 
extranets. These secure extranets provide safe transport of data to and from the Business 
Communications Manager using the public data network (PDN). 
Business Communications Manager expansion unit
The BCM1000e houses a maximum of six additional media bay modules. The cable that comes 
with the expansion unit connects into a DS256 port on the MSC of the BCM1000, and into a 
DS256 port on the center panel of the BCM1000e. Refer to 
This cable, called a Category 5, DS256 or RJ45 cable, must be 5 m (16 ft.) long.
Note: 
The number of modules that actually can be installed is determined by the number 
of DS30 channels required by the modules and the number of channels available.
