SSH TBR 033:1997

Integrated Services Digital Network (ISDN); Attachment requirements for packet mode terminal equipment to connect to an ISDN using ISDN basic access

Scope

This Technical Basis for Regulation (TBR) specifies the technical requirements under articles 4(c) to 4(f) of Directive 91/263/EEC for Terminal Equipment (TE) to be attached to the pan-European Integrated Services Digital Network (ISDN) at an interface at the T reference point or coincident S and T reference point for a basic access. These requirements are intended to ensure that the essential requirements of Directive 91/263/EEC continue to be met when up to eight Terminal Equipments are simultaneously connected at the coincident S and T reference point. These requirements are taken from TBR 3 [9], ETS 300 007 [10], ETS 300 047-3 [12], ETS 300 012 [11], ETS 300 102-1 [13] and ETS 300 125 [14]. This TBR does not contain the essential requirements of Article 4 (g) for interworking via the public network, and so does not provide any guarantee of correct terminal-to-terminal operation.
