MINI-MODEM V.92
Appendix C: Connecting to a Cisco
Router
This appendix provides information on how to connect a Mini-Modem V.92 to a
Cisco
®
router.
C.1 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.

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#Sxxxxxxxx
, where xxxxxxxx is your password (one to eight 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 (one to eight characters long), and press
ENTER
.
