The PGW Support of HSI Non-RAS Mode feature was introduced on the Cisco MGC software.
This document describes support for the Non-RAS mode of operation on Cisco PGW 2200. This feature is described in the following sections:

Feature Overview
The PGW Support of HSI Non-RAS Mode feature of the Cisco Media Gateway Controller (MGC) software runs on the Cisco PGW 2200 and Cisco H.323 Signaling Interface (HSI). It enables service providers to create a simplified network without a gatekeeper, for networks that do not require gatekeeper features, such as security.
In Non-RAS mode, the Cisco PGW converts called numbers into one or two IP addresses in the dial plan to support load sharing over multiple HSIs, which supports H.323 endpoints that have multiple IP addresses. With such support, when the primary IP address does not work, a subsequent attempt is made with the alternative IP address for the same endpoint.
If the Cisco PGW sends an IP address to the HSI over E-ISUP, the HSI sends a SETUP directly to the endpoint. In addition, the Cisco PGW stores the H.323 destination IP address in the Cisco PGW Call Detail Record (CDR).
PGW Support of HSI Non-RAS Mode enables a Cisco PGW 2200 to be deployed with a connected Cisco HSI without a gatekeeper in networks that do not require admission or location of the H.323 endpoint. PGW Support of HSI Non-RAS Mode is also used when selection of the endpoint does not benefit from H.323 mechanisms such as Resource Availability Indication (RAI). Examples of such deployments include Cisco CallManager (CCM), H.323 ITS, or cases in which an H.323 gateway provides the only connection to a PBX.
CDR Tag 4236
CDR tag 4236 supports non-RAS mode by storing the H.323 destination IP address. This tag is available only when the call uses the non-RAS feature.
The information in Table 1 describes the H323 destination tag created for Non-RAS mode.
Benefits
The Non-RAS mode of operation enables you to deploy the Cisco PGW 2200 and the Cisco HSI without a gatekeeper. Such a deployment establishes a simplified network that does not require admission, location of the H.323 endpoint, or selection of an endpoint that does not benefit from H.323 mechanisms such as RAI. Examples are CCM, H.323 ITS, and an H.323 gateway that contains the only connection to a PBX.
Restrictions
A single Cisco HSI cannot operate in both RAS and Non-RAS modes. If a network requires both modes of operation, the network must have multiple Cisco HSIs.

Supported Platforms
The hardware platforms supported for the Cisco MGC software, Release 9.7(3), are described in the Cisco Media Gateway Controller Hardware Installation Guide.
The hardware platforms supported for the Cisco HSI software, Release 4.2, are described in the Cisco H.323 Signaling Interface User Guide.
Supported Standards, MIBs, and RFCs
No new standards, MIBs, or RFCs are supported by the PGW Support of HSI Non-RAS Mode feature.
Prerequisites
To implement the Non-RAS mode of operation, the feature must be enabled on both the Cisco PGW 2200 and the Cisco HSI.
The Cisco PGW 2200 must be running Cisco MGC software Release 9.7(3). Prerequisites for this release can be found in the Release Notes for the Cisco Media Gateway Controller Software Release Cisco MGC Software Release 9.7(3) at:
http://www.cisco.com/univercd/cc/td/doc/product/access/sc/rel9/relnote/rn973.htm.
The Cisco HSI must be running Cisco HSI Release 4.2.
Configuration Tasks
This section contains the steps necessary for configuration of the Cisco MGC software to support this feature.
See the following sections for configuration tasks for the PGW Support of HSI Non-RAS Mode feature:
MGC Configuration
To enable NON-RAS mode on the Media Gateway Controller, you must configure the sigPath/Trunkgroup property identified as H323Destination. Non-RAS mode supports configuring two destination addresses, a primary IP address and an alternative IP address.
Note
The sigPath property H323adjunct link must be set to 1 to indicate the EISUP sigPath is between the PGW 2200 and the HSI.
mml> prov-add:SIGSVCPROP:name="eisupsvc1",h323adjunctlink="1"Configuring a Primary Destination Address
In the following MML command example, a primary destination IP address is configured, but no alternative address. In this example, a port number is provided, the default port 1720.
mml> prov-add:TRNKGRPPROP:name="111",H323Destination="192.168.80.2:1721"Configuring Primary and Alternative Destination Addresses
In the following MML command example, two IP addresses are configured. The primary destination IP address is 192.168.80.2:1720; the alternative destination IP address is 192.168.80.3.
mml> prov-add:TRNKGRPPROP:name="111",H323Destination="192.168.80.2;192.168.80.3"
Note
When two destinations are used for a route trunk group, the reattempt value must be set to 1, as in the following MML command.
mml> prov-add:rttrnkgrp:name="111",type=4,reattempts=1,queuing=0,cutthrough=2,resincperc=0Configuring Gatekeeper Mode for the Trunk Group
In the following MML command example, the gatekeeper mode is configured for the trunk group:
mml> prov-add:TRNKGRPPROP:name="111",H323Destination="0.0.0.0"HSI Configuration
For the Cisco HSI software configuration required to support the Non-RAS Mode of operation, refer to the Cisco H.323 Signaling Interface User Guide, for Release 4.2.
To enable Non-RAS mode on the Cisco HSI, enter the following MML command:
prov-add:name=RAS,manualRASTroubleshooting Tips
For information on troubleshooting the rest of the Cisco MGC software, refer to the Cisco Media Gateway Controller Software Release 9 Operations, Maintenance, and Troubleshooting Guide.
Configuration Examples
To enable Non-RAS mode, one must configure new properties identified as sigPath/Trunkgroup. Non-RAS mode supports configuring two destination addresses, a primary IP address and an alternative IP address.
Note
The sigPath property H323adjunct link must be set to 1 to indicate the EISUP sigPath is between the PGW 2200 and the HSI.
mml> prov-add:SIGSVCPROP:name="eisupsvc1",h323adjunctlink="1"In the following MML command example, two IP addresses are configured. The primary destination IP address is 192.168.80.2:1720; the alternative destination IP address is 192.168.80.3.
mml> prov-add:TRNKGRPPROP:name="111",H323Destination="192.168.80.2;192.168.80.3"
Note
When two destinations are used for a route trunk group, the reattempt value must be set to 1, as in the following MML command.
