CHAPTER 5: Remote Configuration

5.Remote Configuration

5.1Introduction

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 Portable USB Modem for maintenance or troubleshooting as if you were on-site.

5.2 Basic Procedure

The following steps are valid regardless of whether the connection is established by the local or the remote modem.

1.Establish a data connection with a remote modem.

2.Send three remote configuration escape characters followed by AT and the setup password, and press ENTER. Example: %%%ATblackbox<CR>. 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<CR>, then type ATO<CR> 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, it may lock up the remote modem.

5.3 Setup

The Portable USB Modem is shipped with a default setup password (blackbox). Because anyone who has an owner’s manual knows the default setup password, for security you should change the password and possibly also the remote configuration escape character.
