Section 3 Commissioning the Cisco AS5800 Hardware
Configuring Modems and Lines
Task 5. Configuring Modems and Lines
Modems and lines are configured after:

The serial channels are operational

POTS telephone calls are successfully routed to the modems
Each modem is mapped to a dedicated asynchronous line inside the NAS. After the
modem inout
command is applied to the lines, the NAS is ready to accept modem calls.
AAA security is applied to the lines by the
aaa new-model
command and
aaa authentication login
default local
command. AAA performs login authentication by using the local username database.
The login keyword authenticates EXEC shell users.
Note
The modem speed 115200 bps and hardware flow control are the defaults for
integrated modems.
Step 1
Configure modem control (DCD/DTR) for incoming and outgoing modem calls:
!
line 1/2/00 1/10/143
modem InOut
!
Note
The
no modem log rs232
command limits the size of the
show modem log
command’s output.
Step 2
Understand the modem-numbering scheme for the Cisco AS5800. Modems use the
shelf
/
slot
/
port
notation.
