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.

The type of display output generated from the show modem slot/port command depends on the version of Cisco IOS software running on the router or access server. For example, the following example shows an example output for a 56K modem card, which carries digital modems that transmit at 56 kbps.

Note 56K modems do not modulate or demodulate data. A pure digital-to-digital connection is

made.

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]]

show modem connect-speeds

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

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.

Release Modification

11.3 This command was introduced.

12.1(5)T This command was modified to show display output for Cisco 3600 series digital modems that support V.110.

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.

Command Connect Speed Range Displayed

show modem connect-speeds 56000 40,000 to 56,000 bps

show modem connect-speeds 38000 24,000 to 38,000 bps

Command Connect Speed Range Displayed

show modem connect-speeds 21600 2,400 to 21,600 bps

show modem connect-speeds 1200 75 to 1200 bps

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.
