V.110 Support for Cisco 3600 Series Digital
Modems
This feature implements the V.110 protocol on Cisco digital modem network modules (NM-6DM,
NM-12DM, NM-18DM, NM-24DM, and NM-30DM) for the Cisco 3600 series of routers, and provides
V.110 support for digital modems connected over BRI or PRI interfaces.
This document contains the following sections:
•Feature Overview, page 1
•Supported Platforms, page 2
•Supported Standards, MIBs, and RFCs, page 2
•Command Reference, page 4
•Glossary, page 24
Feature Overview
V.110 is a real-time method of encapsulating varying data rates and the associated RS-232 signals into
a 64-Kbps ISDN B-channel. Using this procedure, asynchronous data rates from 600 bps to 38.4 Kpbs
can be transparently rate-adapted over a single 64-Kbps channel.
V.110 is useful for transporting data over GSM-type mobile phones. V.110 over ISDN support is being
added to the MARS platform to support digital modems in many countries which use E1 with ISDN.
V.110, as an alternative to V.120, is a method of ISDN rate adaption. It provides DTEs with V-series
type interfaces with access to ISDN networks by bit stuffing. Many V.110 devices are used in Europe
and Japan.
Benefits
The V.110 recommendation of the ITU-T rate adapts a low-speed connection to an ISDN B-channel,
allowing the remote station or terminal adapter to use the fast call-setup times offered by ISDN. This
feature enables Global System for Communications (GSM) wireless connectivity.

connection requests that the modem answered and successfully or
unsuccessfully connected with the remote DCE device.
•Outgoing completes and failures—Total number of outgoing
connection requests that the modem dialed and successfully or
unsuccessfully connected with the remote DCE device.
•Failed dial attempts—Number of times the modem attempted to dial
out but the call failed to leave the modem.
•Ring no answers—Number of times the integrated modem detected
ringing but did not answer the incoming call.
•Busied outs—Number of times the integrated modem was intentionally
taken out of service (for example, the modem busyout command was
enabled on the modem).
•No dial tones—Number of times the dial-out attempt failed because the
modem failed to detect a dial tone.
•Dial timeouts—Number of times the modem has timed out while
attempting to dial.
•Watchdog timeouts—Number of times the modem internal watchdog
timer has expired.
•No carriers—Number of times the modem disconnected because no
carrier was present.
•Link failures—Number of times the modem has detected a link failure.
•Resets—Number of times the modem has been reset.
•recover oob—Number of times the out-of-band feature has been
cleared and reinitialized.
•Protocol timeouts and errors—Number of times the modem protocol
failed to make a call connection.

Cisco IOS Release 12.1(5)T
show modem connect-speeds
To display connection speed statistics for all modems running in an access server or router, use the show
modem connect-speeds EXEC command. There is no no form of this command.
show modem connect-speeds [max-speed [slot]]
Syntax Description
Defaults The maximum speed displayed is 12,000 bps.
Command Modes EXEC
Command History
Usage Guidelines Because most terminal screens are not wide enough to display the entire range of connection speeds at
one time (for example, 75 to 56,000 bps), the max-speed variable is used. This variable specifies the
contents of a shifting baud-rate window, which provides you with a snapshot of modem connection
speeds for your system. If you want to see a snapshot of lower baud rates, specify a lower connection
speed. If you want to see a snapshot of higher baud rates, specify a higher connection speed.
The Cisco IOS software rounds up the max-speed variable to the nearest recognizable baud rate, so you
do not need to memorize or enter exact connection speeds. For example, if you enter a maximum baud
rate of 22059, the system software automatically rounds the value up to 24000.
To display a complete picture of all connection speeds and counters on the system, you must enter a
series of commands. Each time you issue the show modem connect-speeds max-speed command, only
nine baud rate columns can be displayed at the same time.
Table 3 shows a range of commands that you can issue, one at a time, to see a complete picture of the
total possible connection speeds on your access server.
Table 3 Connect Speed Displays for show modem connect-speeds
Command
max-speed (Optional) Maximum speed you want displayed in the shifting speed
window. You can specify from 12,000 to 56,000 bps.
slot (Optional) Specifies the slot number, which limits the display output to a
particular range of modems in the system.

Note The Cisco IOS software does not accept commas (,) in the connect speed field. For
example, enter 28000 not 28,000.
The show modem connect-speeds command displays a log of connection speed statistics starting from
the last time the access servers or router was power cycled or the clear modem counters command was
issued. If you want to create a monthly report of the connection speeds achieved by the modems, issue
the clear modem counters command at the beginning of the month and issue the show modem
connect-speeds command at the end of the month.
