• microcom_mimic—Cisco (Microcom) internal analog modem (NM-AM–2600/3600)
• microcom_server—Cisco (Microcom) V.34/56K internal digital modem (AS5200)
Enter these modemcap names with the modem autoconfigure type command.
For more information on creating and using modemcaps refer to the TAC Tech Notes documentation,
Recommended Modemcaps for Internal Digital and Analog Modems on Cisco Access Servers, at the
following URL: http://www.cisco.com/warp/public/471/recc_modemcaps.html
If your modem is not on this list and if you know what modem initialization string you need to use with
it, you can create your own modemcap; see the following procedure, “Using the Modem Autoconfigure
Type Modemcap Feature.” To have the Cisco IOS determine what type of modem you have, use the
modem autoconfigure discovery command to configure it, as described in the procedure “Using the
Modem Autoconfigure Discovery Feature.”
Note When configuring an internal modem, avoid using the Modem Autoconfigure Discovery feature
because the feature can misdetect the internal modem type and cause the modem to start working in
an unpredictable and unreproducable manner.
Using the Modem Autoconfigure Type Modemcap Feature
If you know what modem initialization string you need to use with your modem, you can create your
own modemcap by performing the following steps.
Step 1 Use the modemcap edit command to define your own modemcap entry.
The following example defines modemcap MODEMCAPNAME:
Router(config)# modemcap edit MODEMCAPNAME miscellaneous &FS0=1&D3
Step 2 Apply the modemcap to the modem lines as shown in the following example:
Router# terminal monitor
Router# debug confmodem
Modem Configuration Database debugging is on
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#line 33 34
Router(config-line)#modem autoconfigure type MODEMCAPNAME

Note The report that is generated by the debug confmodem command can be misleading for the MICA
and NextPort internal modems because these modems do not have Universal Asynchronous
Receiver/Transmitter (UART) and exchange data with the CPU at speeds of hundreds of kbps.
