Appendix E - Using Out Of Band Management - Multitech MultiModem ZBA MT9234ZBA User Manual

Appendix E – Using Out of Band Management
This appendix covers the setting up of a router. The router's console port, for example on a Cisco router, is an asynchronous
serial port configured as data communications equipment (DCE).
Step 1: Configure the Modem for your Country or Region
Configure the modem defaults to match the requirements of the country/region in which it will be used. For information on
how to do this, see "Step 5: Configure the Modem for your Country or Region" in Chapter 2.
Step 2: Configure for Callback Security in Direct Connect Mode
Callback security requires a caller to give a correct password before sending data to the system. If you do not plan to use
this feature, skip to Step 3.
To Turn Direct Connect Callback Security On and Off
Callback security must be turned on to enter many callback security commands.
Using a terminal program such as HyperTerminal, type the command AT#Sxxxxxxxx, where xxxxxxxx is your
password (1 to 8 characters long; case-sensitive). Press E
password is correct and ERROR if it is wrong. The default password is MTSMODEM. If you wish to change the
password, then type the command AT#S=xxxxxxxx, where xxxxxxxx is the new password (1 to 8 characters
long; case-sensitive), and press E
Type one of the following commands:
•
•
Type AT&W0 to store the above commands to nonvolatile memory.
To Set the Parity of the Callback Security Messages
The modem's password prompt and messages parity must match the parity of the computer to which the modem is
connected.
