PTIONS
Three options allow you to specify
the criteria the modem will use in
determining when to enter and
exit the Leased Line Auto-Recovery
mode:
Leased Line Auto-Recovery Select
(Select)
This option determines the type of
Leased Line Auto-Recovery
desired. "DIAL IF BAD>(1, 2, 3, or
4) min" or "DIAL IF BAD>30 s
(seconds)" means dial backup will
occur if bad line conditions are
present for the specified (selected)
time period. To disable the Leased
Line Auto Recovery, select NO
AUTO RECOVERY. A sixth option,
Manual Recovery, is discussed
below.
NOTE
If "DIAL IF BAD>(1, 2, 3, or 4
4) min (or 30 s)" is selected,
the Select option settings of
the answer and originate
units must be the same.

UTO ECOVERY
Manual Recovery
If both modems are set for
MANUAL RECOVERY, the
originate unit can be used to
autodial the number stored via the
PHONE screen without having to
change the LINE TYPE setting on
either unit. To autodial, access the
AUTO-DIAL screen and select
DIAL. To return to the leased line,
select HANGUP from the AUTO-
DIAL screen.
Return from Leased Line Auto-Recovery
(RETN)
This option determines the criteria
for exiting Leased Line Auto-
Recovery mode.
"RETURN IF GOOD>(10, 40, 60,
or 120)s" means the modem will
automatically exit the Leased Line
Auto-Recovery mode when it tests
and finds the leased line in good
condition for more than the time
period specified (10, 40, 60, or 120
s). If the Return option is set to
OFF, the modem will stay in the
Auto-Recovery mode indefinitely,
unless you select HANGUP from
the AUTO-DIAL screen or unless a
loss of line current or other normal
disconnect occurs. Either event will
return communication to the
leased line.
NOTE
The Return option setting
must be the same on both
communicating units.
