PT2 =Auto The auto-call unit attempts to tone dial when initiating a call. If tone dialing is not possible,
pulse dialing is used.
For this feature to work correctly, the first character in a dial string must be a digit. A T or P in
the dial string overrides this setting, for that dial string.

If successful, the modem responds with OK
Rmt Acc
Remote Access
Determines whether your modem can be configured by a remote modem.

RA1 =Enable The local modem can be configured by a remote modem.
Rmt Cnfg
Initiate/Terminate, or Abort Remote Configuration Session
Lets you initiate, terminate, or abort a remote configuration session with the connected modem.
AT

RC0 =Terminate The modem terminates a remote configuration session with the connected modem. Changes to
the remote modem’s configuration are saved. This setting is not displayed unless you are
already in a remote configuration session.

RC1 =Abort The modem aborts a remote configuration session with the connected modem. Changes made
to the remote modem’s configuration are not saved. This setting is not displayed unless you are
already in a remote configuration session.

RC2 Init Rmt Cnfg? The modem attempts to initiate a remote configuration session with the connected modem. For
instructions on initiating a remote configuration session with a dial/leased line modem, or
terminating or aborting a remote configuration session, refer to Chapter 1 of the
326X Series
Modem Reference Guide.

Redial Last
Number
With this command, the modem redials a call until a successful connection is made or the call
has been attempted
n
times. This command causes your modem to redial the
last
number
dialed.
Restore
Initiate/Terminate Restoral
Determines how modems operating on a leased line handle initiation of a dial restoral session.
The modem has four ways of initiating restoral: automatic, manual, DTE signal, or DTE ACU.
The restoral option is available in models: 3261, 3263, 3266, and the 3268.
AT
*
RE0 =Off Disables the initiation of restoral.
AT
*
RE1 Restore=FP Only Manual initiation lets you initiate and terminate restoral by pressing the Talk/Data key ( key
in the Home position) on the modem’s front panel.
AT
*
RE2 =FP/108.1 The modem lets the DTE initiate restoral using DTR. In DTR restoral, an off-to-on DTR
transition from the DTE interface initiates restoral. This option is provided for DTEs that
cannot manipulate Circuit 116 for restoral purposes.
AT
*
RE3 =FP/116 The modem allows the DTE to initiate restoral with Circuit 116. Circuit 116 lets you use
off-to-on transitions of this signal from the DTE to initiate restoral, according to ITU V.24
specifications.
AT
*
RE4 =FP/Auto In automatic restoral, the originating modem on the leased line determines when restoral takes
place. The answer modem cannot automatically initiate restoral; it can only answer an inbound
call, thus ensuring that both modems do not try to call each other at the same time. Such an
occurrence would result in a failed restoral attempt.
