This will be relevant in the Gateway decomposition audio conference. Note that this charter is still being discussed in the IETF and the wording is not yet final. The new WG will be in place in time to hold its first meeting at the December IETF meeting in Orlando, the week of Dec 7, 1998.

Description of Working Group:

The working group will develop an informational RFC detailing the architecture and requirements for controlling PSTN (Public Switched Telephone Network) Media Gateways from external control elements such as a media gateway controller. A PSTN media gateway is a network element that provides conversion between the audio information carried on telephone circuits and data packets carried over the Internet or over other packet networks. This work will be done in consultation with other IETF working groups looking at similar issue. The working group will also ensure that good information conduits exist with groups in other standards groups with expertise in the relevant PSTN technology.

This working group will also define standards track protocol(s) for controlling PSTN (Public Switched Telephone Network) Media Gateways from external control elements such as a media gateway controller. .

Examples of PSTN media gateways are: * Trunking gateways that interface between the telephone network and a Voice over IP network. Such gateways typically manage a large number of digital virtual circuits. * Access gateway that provide traditional analog or PRI line interfaces to a Voice over IP network. * Network Access Servers that can attach a "modem" to a telephone circuit and provide data access to the Internet.

This working group assumes a separation of call control where there is call control "intelligence" outside the media gateways that is handled by a media gateway controller. This allows for scalability and simplified management: many media gateways within a domain can be controlled by one media gateway controller.

This group will NOT work on media gateway controller to media gateway controller protocols, nor on media gateway to media gateway protocols.

Planned output: * Architecture & Requirements informational RFC * standards track RFC for the protocol between a media gateway controller and a media gateway.

Goals and Milestones:
