Configuring Modems and Lines
Step 3
Test the configuration by sending a standard telephone (POTS) call into the NAS. The configuration
works if the modem answers (that is, you hear modem squelch), the configuration works. Figure 2-5
shows how this step works.
Figure 2-5 Sending a POTs Telephone Call into a NAS
A different telephone number is associated with each end of the connection. In Figure 2-5, the called
number 555-1234 is assigned to the PRI trunk. This number is dialed from the POTS telephone. The
calling number 444-1234 is assigned to the POTS telephone line.
Task 5. Configuring Modems and Lines
Modems and lines are configured after:

The ISDN 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 default settings
for integrated modems.
Step 1
Support incoming and outgoing modem calls. In this example, the NAS has 96 integrated modems.
