Remote Configuration
The configuration of the modem described in Step 3 contains the core settings that allow the modem to function properly on
the console port of the Cisco router. Commands in this section may be done remotely by calling into the MT5634ZBA attached
to the console port with another modem.
Note: You cannot remotely configure country/region nor turn on callback security. You cannot remotely execute commands if
the remote modem is set for callback security; remote configuration of a modem so configured is not recommended.
1. Establish a data connection with a remote MT5634ZBA modem.
2. Send three remote configuration escape characters followed by AT and the setup password, and then press E
NTER.
Example: %%%ATMTSMODEM. You have four tries to enter the correct password before being disconnected. If the
password is correct, the remote modem may respond with OK.
Note: If the modem has previously been configured with command echo off and result codes off, it may be difficult to
determine if the remote modem is responding to commands. The ATI command can be used for this purpose. Even with echo
and result codes off, the modem will respond with the requested ID string if it is properly receiving the command.
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.
Note: This step is important to ensure that the connection is broken cleanly.
