DBU Timers
Fail Timer (FAIL TMR x 10)
This option sets the amount of time the dedicated circuit failure condition
must be active before the IQ Probe attempts backup. The value entered is
multiplied by 10. The amount of time can be up to 990 seconds (i.e., an en-
try of 99). The factory default setting is 10 seconds (an entry of 1).
Restore Timer (RESTORE TMR)
Once the circuit is down, the IQ Probe remains in backup until the circuit
is active for the length of time specified for the restore timer. The selection
is entered in minutes (up to 255). If set to 0, the line must be restored man-
ually. The factory default setting is 1 minute.
Redial Counter
This option sets the number of times the IQ Probe redials the far end when
entering backup mode. The redial count, which is manually entered, can
be up to a maximum of 99 attempts. If the IQ Probe encounters a busy or
reorder, it attempts to establish the call the specified number of times. The
factory default setting is 5.
Redial Delay
This option works in conjunction with the preceding R
EDIAL
C
OUNTER
. It
selects the amount of time between redial attempts to connect the backup
line. The amount of time, which is manually entered, can be up to 99 sec-
onds. The factory default setting is 15 seconds.
