Basic V110 for MICA Modems on
Cisco Access Servers
Feature Overview
This feature allows V.110 calls to be originated and terminated over ISDN. 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 adaptor to use the fast call set-up times offered by ISDN. This feature
enables GSM wireless connectivity.
This document describes the Cisco IOS commands and AT commands required to support V.110 on
MICA modems for AS5

Note This feature is distinct from the Asynchronous Management Protocol for V.110 Terminal Adaptor Module that runs in the Cisco AS5200 and Cisco AS5300. Benefits V.110 is a digital link access protocol and for Cisco access servers. It operates over an ISDN B channel. V.110 enables Cisco access servers to connect to ISDN terminal adapters requiring V.110 compatibility. This feature enables GSM wireless connectivity. This ISDN feature is in addition to the existing analog capability of the MIC

By specifying a value 8 in S29, the user causes the remote modem to implicitly assume that a V.110 connection is to be established. This command indicates that an ISDN call is being requested, and when used with the S29=8 command, results in modem code issuing a ISDN_DIALSTRING (0x45) request being made to the host. After entering the S29=8 command, you can enter the desired user rate if different from the default value of 9600 bps. This command takes the form: S57=speed. For supported rates
