Modulation Protocols

V.22 and V.22bis Protocols

V.22 protocol is used for 1200 bps and 600 bps full-duplex connections. The version of V.22 your modem supports is Alternative B.

V.22bis protocol enhances V.22 by adding 2400 bps full-duplex connections.

NOTE

For V.22 at 600 bps, both modems must be set to 600 bps.

V.21 Protocol

V.21 protocol is used for 300 bps full-duplex connections. The features described in this manual apply to V.21 operation except that your modem does not support:

•V.54 digital and analog loopback.

•LAPM connections.

NOTE

When your modem establishes a V.21 connection, it displays CONNECT V.21/REL - MNP. With a normal or direct V.21 connection, the message is CONNECT.

Bell 212A Protocol

Bell 212A protocol is for 1200 bps full-duplex connections.
