Appendix E - Connecting to a Cisco Router
This appendix provides information on how to connect an MT5634ZBA-V-V92 modem to a Cisco®
router.
Connecting to a Cisco Router Console Port
The console port on the Cisco IOS® router is an asynchronous serial port configured as data
communications equipment (DCE). For Cisco 1000, 1600, 2500, 2600, and 3600 series routers, the
console port uses an RJ-45 connector.
WARNING: Do not connect the modem to the Cisco router’s auxiliary port. This procedure and
document apply only to the Cisco router’s console port.
Step 1: Configure the Modem for your Country
Configure the modem defaults to match the requirements of the country in which it will be used. For
information on how to do this, see “Step 5: Configure the Modem for your Country” 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.
Note: Setting the modem for callback security in direct connect mode disables the remote
configuration feature of the modem.
To Turn Direct Connect Callback Security On and Off
Callback security must be turned on to enter many callback security commands.
1. Using a terminal program such as HyperTerminal, type the command AT#S
xxxxxxxx
, where
xxxxxxxx
is your password (1 to 8 characters long), and press ENTER. The modem responds with
OK
if the setup 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), and press ENTER.
2. Type one of the following commands:
To turn on remote callback security only, type AT#CBS2 and press ENTER.
To turn on both local and remote callback security, type AT#CBS1 and press ENTER. When
local security is turned on, you must enter the setup password before you can enter any AT
command from a local terminal except the AT, ATI
n
, and AT#S
xxxxxxxx
commands.
3. Type AT&W0 to store the above commands to nonvolatile memory.
Note: For other callback security modes of operation, see Chapter 6.
