Scope, Purpose and Application

This document specifies classes of Quality of Service (QOS) sufficient to support Business Multimedia Conferencing on Internet Protocol (IP) networks, defined as equivalent to legacy conference system performance (e.g., H.320 at Basic Rate Interface (BRI) rates).

It also specifies the threshold of perceptible impairment for some user interface parameters. This standard applies to communications between a subset of multimedia end-points, namely Video Teleconference room systems and Desktop systems.

The current scope is limited to H.323 point-to-point communication (Multipoint communication is for further study).

It applies to cases where IP is utilized between the end-points (e.g., IP/Circuit-Switched Hybrid Network connections are for further study, e.g. networks supporting H.320-compliant terminals).
