ETSI - ETS 300 185-1

Integrated Services Digital Network (ISDN); Conference Call, Add-on (CONF) Supplementary Service Digital Subscriber Signalling System No. One (DSS1) Protocol Part 1: Protocol Specification

inactive
Organization: ETSI
Publication Date: 1 January 1993
Status: inactive
Page Count: 72
scope:

This first part of ETS 300 185 specifies the stage three of the Conference call, add-on (CONF) supplementary service for the pan-European Integrated Services Digital Network (ISDN) as provided by European public telecommunications operators at the T reference point or coincident S and T reference point (as defined in CCITT Recommendation I.411 [1]) by means of the Digital Subscriber Signalling System No. one (DSS1). Stage 3 identifies the protocol procedures and switching functions needed to support a telecommunications service (see CCITT Recommendation I.130 [2]).

In addition, this standard specifies the protocol requirements at the T reference point where the service is provided to the user via an intermediate private ISDN.

This standard does not specify the additional protocol requirements where the service is provided to the user via a telecommunications network that is not an ISDN.

The CONF supplementary service provides a user with the ability to have a multi-connection call, i.e. a simultaneous communication between more than two parties.

The CONF supplementary service is applicable to all telecommunication services carrying speech.

Further parts of this standard specify the method of testing required to identify conformance to this standard.

This standard is applicable to equipment supporting the CONF supplementary service, to be attached at either side of a T reference point or coincident S and T reference point when used as an access to the public ISDN.
