Control Procedure (Modem-to-Modem)

Enabling Modem-to-Modem Remote Control Mode

To remotely control a modem connected by a direct phone link,

access REMOTE screen 1 (shown below).

If you select CONTROL, you will be able to control the front panel of the

remote modem from the front panel of the modem you are using. When

you select CONTROL, you will see (on the LCD of the modem you are using)

whatever is currently displayed on the LCD of the remote modem. The

characters on the LCD will be displayed in lower case—this is to let you

know you are actually looking at a “copy” of the LCD of the remote modem.

Buttons pressed on the front panel of the controlling modem will affect the

controlled modem (and not the controlling modem). When you are remotely

controlling another modem, the LCD will not change as quickly as it normally

does.

NOTE

While a Modem 34336 is being remotely controlled by another Modem

34336 or is remotely controlling another Modem 34336, its diagnostic

port cannot be used for other purposes—commands from the diagnostic

port will be ignored.

(You can also access two remote test options from REMOTE 1 screen by

selecting TEST. These test options, remote digital loopback and remote

digital loopback self test, are described in Chapter 7.)

Exiting from Remote Control Mode

To exit from remote control mode, press the ENT pushbutton five times in

succession on the front panel of the controlling modem. (If the remote

modem resets as a result of a configuration change, the local modem will

appear to have no control. To remedy this situation, press the ENT button

five times.)
