Chapter 7 - Callback Security and Remote Configuration
7.3 Remote Configuration Description
The Remote Configuration feature is a network management tool that allows you to configure
modems remotely. This means you could configure modems anywhere in your network from one
location without having to visit the sites or rely on remote users to follow your instructions. With
Remote Configuration, which is protected by two level security, you can download new parameters,
program new V.42 capabilities and implement new features. Remote Configuration also makes
troubleshooting a remote location a lot easier.
The way Remote Configuration works is that S-Register S13 has been set up to contain the special
Remote Configuration escape code. When calling a Remote Configuration equipped modem, you
enter the proper Remote Escape code to enable entering your Set up Password. After entering it, you
can then execute AT commands as if you were connected locally. If you set S-Register S13 to zero,
Remote Configuration is disabled.
7.3.1 Initial Setup Procedures for Callback and Remote
Configuration.
Your modem was shipped with a default LOGIN Password and Setup Password (LOGIN=MULTI-
TECH and Set-up=MODEMSETUP) so that you have access to the features used for configuring the
modem. Because the defaults are in the modem owner’s manual, and anyone can find out what they
are, you should change the codes as the first step of your initialization procedure.
Table 7-1. Modem LOGIN, Setup and Remote Escape Code Procedures
To change your modem’s LOGIN Password and Setup Password:
Step Procedure
Note: Passwords are upper/lower case sensitive. The case you enter here is the case that must be
used at Log-In.
1. Type AT#IMULTI-TECH and hit RETURN. Your modem will respond with:
OK (if the LOGIN Password is wrong, the modem’s response is ERROR)
2. Type AT#SMODEMSETUP and hit RETURN. Your modem will respond with the following:
OK (or ERROR if wrong Setup Password)
Note: At this point you can change the LOGIN Password and Setup Password.
3. Type AT#I=xxxxxxxxxx (with any keyboard characters used, minimum 6 maximum 10) and hit
RETURN. Your modem responds with:
OK
4. Type AT#S=yyyyyyyyyy (with keyboard characters used, minimum 6 maximum 10) and hit
RETURN. Your modem responds with:
OK
To change your Remote Configuration feature status:
5. If you want Remote Configuration off, set S-Register S13 to 0 (zero). Refer to Chapter 6 for
details on how to set S-Register values.
6. If you want Remote Configuration on and wish to change the Remote Escape Character, change
the S-Register S13 value. If you leave it at the default value, decimal 37 (% sign) will be your
modem’s remote escape character.
