Chapter 4 – Remotely Configuring
Modems
Remote configuration is a network management tool that allows you to configure modems anywhere in your network from one location. With password protected remote configuration, you can issue AT commands to a remote MultiModem product for maintenance or troubleshooting as if you were on site.
Remote Configuration Overview
The following steps are valid regardless of whether the connection is established by the local or the remote Multi‐ Tech modem.
1.Establish a data connection with a remote MultiModem product.
2.Send three remote configuration escape characters followed by AT and the setup password, and press ENTER. Example: %%%ATMTSMODEM. You have four tries to enter the correct password before being disconnected. If the password is correct, the remote modem responds with OK.
3.You can now send AT commands to configure the remote modem.
4.When you have finished configuring the remote modem, save the new configuration by typing AT&W0, and pressing Enter.
5.Type ATO and press Enter to exit remote configuration. You can then break the connection in the normal way.
CAUTION: If you hang up while you are in remote configuration mode, the remote modem might lock up.
Setting Up Modems for Remote Configuration
This section describes how to change the setup password and the remote configuration escape character.
Changing the Setup Password
Modems are shipped with a default setup password (MTSMODEM). As a precaution, change the default setup password for your Multi‐Tech modems.
To change the password:
1.Open a data communications program such as Phone Tools or HyperTerminal.
2.To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and press ENTER. The password can include any keyboard character, and must be one to eight characters long.
3.The modem responds with OK. The new password is saved automatically.
You can now either enter more AT commands or exit the data communications program. The next time you remotely configure the modem you must use the new setup password.
Note: You can only change the setup password locally; you cannot change the password remotely. Also, passwords are case sensitive.
