Integrated Services Digital Network (ISDN); Videotelephony teleservice Functional capabilities and information flows

Scope

This ETS defines the stage two for the videotelephony teleservice of the pan-European Integrated Services Digital Network (ISDN) as provided by European public telecommunications operators. The stage two description identifies the functional capabilities and the information flows needed to support the service description. The stage two description also identifies user operations not directly associated with a call (see CCITT Recommendation I.130 [2]). This ETS is specified according to the methodology specified in CCITT Recommendation Q.65 [4]. In addition, this ETS does not specify the requirements where the service is provided to the user via a private ISDN. This ETS does not specify the requirements for the allocation of defined functional entities within a private ISDN; it does, however, define which functional entities may be allocated to a private ISDN. This ETS does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN.
