Standards Institute (ETSI) The ETSI deals with issues concerning the

each region.

ATM Forum    The ATM Forum was formed in October, 1991 by four companies: Northern Telecom, Sprint, SUN Microsystems, and Digital Equipment Corporation (DEC).

In January 1992, the membership was opened to the industry.

There are 3 categories of membership:

Principal - Participate in technical and marketing committee meetings.

Auditing - Receive copies of the technical and marketing committee documents.User - Participate in End User Roundtable (ENR)

meetings.    

There are three types of committees in the ATM Forum:

Technical Produces implementation specifications and is organized into a number of technical "subject matter expert" sub committees.

Market Awareness and Education (MA&E) Produces tutorials, presentations, press releases, newsletters, and other informative material.

End User Roundtable (ENR) user group Goal- to collect higher level requirements and provide these to the technical and MA&E committees.

Frame Relay forum

Many aspects of frame relay are similar to those of ATM.

They are both connection-oriented protocols, involve ISDN-based signaling, and require similar network management functions.

The ATM Forum and the Frame Relay Forum corroborated closely in the production of Frame Relay/ATM internetworking specifications.

Today, the Frame Relay Forum and the ATM Forum are placing a considerable amount of emphasis on the interoperability of frame relay and ATM services.

There are implementation agreements for communicating frame relay traffic across an ATM network, and for communicating between frame relay end systems and ATM end systems.

This is not limited to basic data transfer but is expanding to include all types of data and ultimately video traffic.

The Frame Relay Forum is currently completing a packetised voice implementation agreement which will go on to be an ATM Forum standard later this year.

Frame relay will be used well into the next century because it provides a needed service now and provides a `natural' data service on future ATM networks.
