Dial-Peer Support for Data Calls


The Dial-Peer Support for Data Calls feature enables the configuration of the dial peers as voice or data. The feature provides a unified call processing model that is scalable for voice and data calls through dial-peer provisioning. The feature also enables the capability of assigning separate number ranges for voice or data calls so that the calls will have the same preference level of matching.

Feature Specifications for Dial-Peer Support for Data Calls

Feature History
 
Release
Modification

12.2(13)T

This feature was introduced.

Supported Platforms

Cisco AS5350, Cisco AS5400, and Cisco AS5850 universal gateways


Determining Platform Support Through Cisco Feature Navigator

Cisco IOS software is packaged in feature sets that are supported on specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.

Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.

To access Cisco  Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:

http://www.cisco.com/register

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

http://www.cisco.com/go/fn

Availability of Cisco IOS Software Images

Platform support for particular Cisco IOS software releases is dependent on the availability of the software images for those platforms. Software images for some platforms may be deferred, delayed, or changed without prior notice. For updated information about platform support and availability of software images for each Cisco IOS software release, refer to the online release notes or, if supported, Cisco Feature Navigator.

Information About Dial-Peer Support for Data Calls

Before Cisco IOS Release 12.2(11)T, a Cisco voice gateway would try to match a voice dial peer before matching and processing a modem call. If a voice dial peer was matched, the call was processed as voice. If there was no voice dial-peer match, then and only then was a call considered to be a modem call. Voice calls always received preference over modem calls. Also, there was no way to assign a subset of addresses in the numbering plan for data calls.

In Cisco IOS Release 12.2(11)T an application called "data_dialpeer" was introduced to enable gateways to identify dial peers. The application enabled the handling of certain matched calls as modem calls. Refer to Fine-Grain Address Segmentation in Dial Peers in Cisco IOS Release 12.2(11)T for more information.

In Cisco IOS Release 12.2(13)T, the Dial-Peer Support for Data Calls feature enables the configuration and order assignment of dial peers so that the gateway can identify incoming calls as voice or data (modem). There are two new commands: dial-peer data and dial-peer search.

How to Configure Dial-Peer Support for Data Calls

See the following sections for configuration tasks for the Dial-Peer Support for Data Calls feature. Each task in the list is identified as either required or optional.

Configure a Dial Peer for Data Calls (required)

Configure a Search for Dial Peers by Type (required)

Configure a Dial Peer for Data Calls

The purpose of this task is to configure your network to identify and process incoming data calls.

SUMMARY STEPS

1. enable

2. configure terminal

3. dial-peer data tag pots

4. incoming called-number string

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables higher privilege levels, such as privileged EXEC mode. Enter your password if prompted.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

dial-peer data tag pots

Example:

Router(config)# dial-peer data 2001 pots

Specifies a dial peer for data calls and enters dial-peer configuration mode. The keyword and argument are as follows:

tag—Specifies the dial-peer identifier. The valid range is from 1 to 2147483647.

Note You cannot have a data dial peer and a voice dial peer that is assigned to the same tag number. The tag must be unique for all dial peers.

pots—Specifies the dial peer as POTS.

Step 4 

incoming called-number string

Example:

Router(dial-peer)# incoming called-number 4085551212

Specifies the incoming called number that is associated with the data dial peer. The string argument specifies the number.


Verifying the Dial-Peer Assignment

Use the show dial-peer voice command to verify the assignment of the dial peers. The following is sample output showing that dial peer 100 is specified as data:

Router# show dial-peer voice 19

dial-peer data

dial-peer search type

dial-peer data

To create a data dial-peer and enter dial-peer configuration mode, use the dial-peer data command in global configuration mode. To delete the data dial-peer, use the no form of this command.

dial-peer data tag pots

no dial-peer data tag

Syntax Description

tag

Specifies the dial-peer number. The valid range is from 1 to 2147483647.

Note You cannot have a data dial peer and a voice dial peer that is assigned to the same tag number. The tag must be unique for all dial peers.

pots

Specifies the incoming POTS dial peer.


Defaults

There is no default behavior or value.

Command Modes

Global configuration

Command History

Release
Modification

12.2(13)T

This command was introduced.


Usage Guidelines

A data dial peer should be defined only for incoming data calls. The incoming called-number and shutdown commands on the data dial peer are allowed. However, the following POTS dial-peer commands are disabled to minimize the run-time impact:

answer-address

carrier-id

destination-pattern

information-type

port

trunk-group-label

Examples

The following example is a data dial-peer configuration:

dial-peer data 100 pots
 incoming called-number 100...

Related Commands

Command
Description

dial-peer search type

Optimizes voice or data dial-peer searches.

incoming called-number

In the following example, the data dial peers are searched first, then the voice dial peers are searched only if no data dial peers can be matched for an incoming call:

dial-peer search type data voice

In the following example the voice dial peers are searched first, then the data dial peers are searched only if no voice dial peers can be matched for an incoming call:

dial-peer search type voice data
