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 311
