Data networking overview

The BCM is a converged voice product, and can be connected to virtually any data network, to
provide Voice over Internet Protocol (VoIP) support in either a Local Area Network (LAN) or
Wide Area Network (WAN) environment. The BCM is also available with an integrated
Broadband Ethernet or ADSL Router, which is intended to provide basic data networking and
services, as well as Virtual Private Network (VPN) connectivity for small sites. Refer to

networking needs, including both VoIP and basic IP networking. The BCM is also available
without a router, to provide VoIP capabilities to networks that already have an existing IP network.

What is data networking?

On the BCM, data networking refers to both standard IP data networks, as well as VoIP. These two
types of networks are closely intertwined, and connect a wide range of IP devices - including IP
telephones and computers - with the BCM and with external networks. The BCM with router can
also handle all routing requirements.
For more information about setting up networks see
page 33.

About the BCM VoIP capability

The BCM provides VoIP functionality both within a LAN (Local Area Network), and across a
WAN. It can contain IP telephones, which act similar to a traditional phone, but send their signals
across data networks in the form of IP packets. The BCM can also contain IP trunks which connect
offices together across an IP network.

Network routing

The BCM is available with and without an internal router. With the router, it can handle all
external connections necessary for a data-network, as well as control security on these
connections. The standalone version of the BCM does not handle routing, but is suitable for IP
networks where a router is already in place. For information on the BCM router see
