Recovery from the front panel, enter the phone number to be dialed followed
by /R (the Dial Line Auto-Recovery command) on the PHONE screen
(shown below).
If you need assistance, see Section 4.2.

phone number to be redialed and the /R command in memory location 0,
by entering the following command:
AT &Z0=T555-4545/R
Dial Line Auto-Recovery is not enabled until you select DIAL from the front

ROCEDURE
If Dial Line Auto-Recovery is enabled and the Modem goes on-hook, it redials
the stored phone number up to 10 times. It redials 5 times at 30-second
intervals, waits 2 hours, and then redials 5 additional times at 30-second
intervals. The Modem stops redialing after 10 attempts.
If a connection is broken, re-established, and broken again, the full sequence
of 10 redial attempts does not occur unless the Modem is on-line for more
than 1 hour. The modem redials, but it is programmed not to exceed more
than 10 redial attempts in 1 hour.
