Receiving ISDN Data Calls
The 3C882 ISDN modem can receive incoming
circuit-switched data calls from other 3C882 ISDN modems
or from ISDN devices.
If Auto Answer is disabled, when a data call comes in, a RING
message is delivered to the RS-232 port upon reception of an
incoming data call to the 3C882 ISDN modem. Enter the
command AT A to answer the incoming data call. A
CONNECT message is then delivered to the RS-232 port upon
successful connection.
If Auto Answer is enabled, the call is automatically answered
and a CONNECT message, indicating the speed of the
connection, is delivered to the RS-232 port.
When the 3C882 ISDN modem receives a voice call, the
B channel LED(s) flash green, and then remain lit once the
call is answered. (If you are running Multilink PPP, both
B channels flash and then remain lit.)
