48Chapter 2 Introducing the BCM hardware

Modem card

The V.92 (or V.90) modem connects the BCM system to the public switched telephone network (PSTN), enabling the BCM system to send and receive data. The modem card is standard on North American systems, while it is optional for APAC and EMEA. The modem kit consists of a modem card, RJ-11 interface, and connector cable. For further information on installation and removal, see “To install a modem card” on page 309 and “To remove the modem card” on page 307.

Figure 19 shows the modem components.

Use the modem connection to:

•manage the BCM system from a different location

•provide dial-up backup for a WAN card
