Step 4
Apply the new entry to the specified lines. Re-enter the
modem autoconfigure
command each time you
change a modemcap. Modem-autoconfigure strings are not applied to busy modems. Modem strings are
applied after modems disconnect.

Oct 25 19:46:06.960 PDT: TTY2: detection speed (115200) response ---OK---
Oct 25 19:46:06.960 PDT: TTY2: Modem command: --AT&F&D2s53=0--
Oct 25 19:46:09.520 PDT: TTY1: Modem configuration succeeded
Oct 25 19:46:09.520 PDT: TTY1: Detected modem speed 115200
Oct 25 19:46:09.520 PDT: TTY1: Done with modem configuration
Oct 25 19:46:09.520 PDT: TTY2: Modem configuration succeeded

5300-NAS(config-line)#
If you want to reset the modem to its factory defaults, do not simply remove the
modem autoconfigure
command. Rather, replace it with another
modem autoconfigure type
name
command where
name
is
a modemcap whose only action is &F. (In recent Cisco IOS releases, the built-in
mica
modemcap entry
will do this.)
Task 3. Gathering and Viewing Call Statistics
Making sure that your modems are connecting at the correct connections speeds is an important aspect
of managing modems. This section details the following methods for gathering and viewing modem
performance statistics:

3.1 Using the Cisco IOS EXEC (CLI)

3.2 Using Modem Call-Record Terse

3.3 Using SNMP
Note
If you detect low connection speeds across all the modems, you may have a faulty
channelized T1/E1 or ISDN PRI line connection.
