SSH ETS 300 144:1994

Integrated Services Digital Network (ISDN); Audiovisual services Frame structure for a 64 kbit/s to 1 920 kbit/s channel and associated syntax for inband signalling

Scope

This ETS specifies the frame structure and the syntax for end-to-end inband signalling for audiovisual services and end-to-end data communication between equipment using single or multiple digital channels (B, H0, H11 or H12) up to 1 920 kbit/s when connected by the pan-European Integrated Services Digital Network (ISDN). Digital audiovisual services are provided by a transmission system in which the relevant signals are multiplexed onto a digital path. This frame structure allows the best use of the total transmission capacity for the various data flows as audio, video, user data, telematic information and special applications. Additionally, signals for the proper functioning of the system are included.
