Modem Management Operations
Note If you detect low connection speeds across all the modems, you may have a faulty
channelized T1/E1 or ISDN PRI line connection.
Using the Cisco IOS EXEC (CLI)
The Cisco IOS software command line interface (CLI) contains many modem management show
commands. Use these commands to gather and view modem statistics. This section provides a bulleted
list detailing some of the most useful commands.

Table 3-11 describes some of the significant fields in the previous example.
Table 3-11 Show Modem Summary Field Descriptions
Field Description
Succ 60005
60,005 calls successfully trained up. The Cisco IOS software saw “DSR” go high
(still does not mean that PPP negotiated successfully).
Fail 4678
4,678 calls came into the modem, the modem went offhook, but the modem did not
train up.
Succ Pct. 92%
The overall success percentage is 92%.
No Ans 8
Eight calls came into the modem but the modem did not go offhook (CPU was too
busy). Unless you misconfigured the NAS, this counter should be very low (under 1%
of the total calls).
