Cisco IOS Release 12.1(5)T
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.

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.
