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 4.)

For leased backup applications, Answer allows the modem to begin a “handshake” process with
the remote modem.

Dial Standby/Return to Dial

When the modem is operating in Dial Backup mode (DialBckUp), Dial Standby and Return to Dial
allow the modem to switch between primary leased-line and primary leased-line backup operation
while still maintaining the backup connection (Figure 3-10). Switching between backup and
primary leased-line operation can be performed manually or automatically. (Refer to the Leased
Line
section in Chapter 4 to enable the Automatic Dial Backup configuration option.)
