Chapter 9. Configuring Dial Backup Options

Answer/Originate

This option specifies whether the FSU 5622 ESP originates or

waits to answer if the dedicated circuit fails. One end must be

set to Originate and the other to Answer. The factory default

setting is Answer.

Answer Always

If enabled, the answer unit answers any incoming call regardless

of failed conditions.

Passcode

The dial backup passcode adds an additional level of security to

the FSU 5622 ESP. A passcode of one to ten characters can be

programmed into the unit.

When a dial backup connection is established, the originate unit

transmits a pre-programmed passcode to the answer unit over

the dial backup connection before the connection is considered

valid. The answer unit compares the received passcode to a pre-

programmed passcode. If the passcode matches, the receive unit

sends a Passcode OK message to the originate unit and goes on-

line. If the passcode does not match, the receive unit sends an

Invalid Passcode message to the originate unit and terminates

the dial backup connection. If a passcode is not received by an

answer unit with passcode enable, or if the Passcode OK

message is not received by an originate unit with passcode

enable, the dial backup connection is terminated.

DBU Criteria

These options specify the DDS conditions that will cause the FSU

5622 ESP to enter the backup mode.

With Out of Service (OOS)

When enabled, the FSU 5622 ESP enters backup mode if an out-

of-service condition is detected. The factory default setting is

Enable.
