22 Chapter 1 Introducing the Business Communications Manager

Data networking components

The data networking components connect the Business Communications Manager system to the local area network (LAN) and/or the wide area network (WAN). These components are installed at the factory.

Modem card (North American systems only) — a V.90 modem that sends and receives data using the public telephone system.

This connection can be used to:

manage the Business Communications Manager system from a different location

provide dialup backup for a WAN card

LAN interface card — a 10/100 BaseT Ethernet network interface card that connects the Business Communications Manager system to the local area network.

WAN interface card — a network interface card with a T1 interface and sync port that connects the Business Communications Manager system to the wide area network (WAN).

The WAN card connects to a T1 PSTN line with an integrated T1 DSU/CSUs (North American). The WAN card can also connect to a T1 PSTN line with an X.21 or V.35 interface (Europe, Middle East, Africa (EMEA)).

Media Services Card

The Media Services Card (MSC), a PCI card, performs call processing and media processing of the voice channels for the Business Communications Manager system, including the VoIP trunks and IP-based telephones. This card also offers connections for auxiliary features, including external, customer-supplied hardware for paging and music-on-hold.

Figure 6 shows the location of the MSC on the BCM1000.
