Answer
For dial backup applications, Answer allows the modem to go off-hook, generate an answer tone,
and begin the handshaking process with the calling modem. Use the Answer function when the
Auto-Answer Ring Count configuration option is disabled. (Refer to the Line Dialer section in
Chapter 5, Configure Branch.)
For leased backup applications, Answer allows the modem to begin a “handshake” process with
the remote modem.

backup and primary leased-line operation can be performed manually or automatically. (Refer to
