The WAN interface cards -1AM and -2AM (WIC-1AM and WIC-2AM) provide one or two internal V.90 analog modems. These WICs can be used for incoming or outgoing analog modem calls. The WIC-2AM features dual RJ-11 connectors, while the WIC-1AM uses one port for connection to a standard telephone line, and the other port to connect to a basic analog telephone for use when the modem is idle.
