Basic V.110 for MICA Modems on Cisco AS5X00 Access Servers
Feature Overview
This Cisco IOS 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 MICA V.110 implementation supports other connect standards (V.34, V.90, and so forth) in addition to V.110. Modems are not dedicated to V.110 only and are allocated dynamically.
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.
Scope of this Document
This document describes the Cisco IOS commands and AT commands required to support V.110 on MICA modems for AS5X00 Access Servers.
This V.110 implementation for calls on MICA modems are managed by special modem code, with the appropriate Cisco IOS image, similarly to other modulation standards. For pointers to information on modem code, see "Related Documents."
For pointers to information on hardware aspects of the Cisco AS5800, see "Related Documents."
For related terms used in this document, see the Glossary at the end of this document.

Benefits
Basic V.110 is a digital link access protocol for Cisco access servers. Basic V.110 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 MICA modems.
Also, some digital cellular networks support data applications via V.110 connecting from the cell phone. These networks place these V.110 calls on the PSTN for interconnecting to the ISP of the end-customer's choice.
The outputs of Cisco IOS show commands have been changed to display additional fields reflecting the V.110 capability.
An added AT command, ATDI, allows the user to command a V.110 modem to originate a V.110 call.
For more information, see the "Command Reference" section.
Restrictions
This basic feature allows a V.110 call to be originated and terminated. Synchronous V.110 is not supported. In addition, V.110 calls must terminate on a TTY asynchronous IOS interface.
Separate counters for analog and digital calls are not currently supported.
Transmission Speeds
The following V.110 bearer rates and intermediate rates (ITU-T Recommendation Q.931) are supported:
•
•
•
•

•

Supported Platforms

Prerequisites
This feature requires special modem code to be downloaded to the MICA Modems. See the modem code information in "Related Documents."
Supported MIBs and RFCs
The current Modem Management MIB objects for MICA modems are used for V.110. One minor change is in the SNMP agent code. This change returns the correct modulation type for V.110 when it does a look up of the modulation for MICA modems.

The calling user can manually communicate with a V.110 modem in order to originate a remote V.110 dialout from the called modem. The AT command set includes the ATDI command (place V.110 call) to allow a V.110 call to be originated from the called modem. After establishing a session with the called MICA modem, you can enter the ATDI command to dial-out a V.110 call from the modem.
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 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 example:
S57=19200For supported rates, see "Restrictions."
