Scope
This European Telecommunication Standard (ETS) contains the requirements to be satisfied by Very Small Aperture Terminal (VSAT) systems for their interconnection to Packet Switched Public Data Networks (PSPDNs) implemented according to the CCITT Recommendation X.25 [1]. This ETS applies to the provision of Packet Switched Data Transmission services as defined in section 2 of CCITT Recommendation X.2 [2]. This ETS is applicable to both one-way and two way VSAT networks. In the case of one-way VSAT networks@ the provision of the services as defined in section 2 of CCITT Recommendation X.2 [2] implies the implementation of return circuits using facilities of other networks (e.g. terrestrial networks). This ETS deals with two types of specification: a) Interface requirements (clause 5): Interface requirements are specified in order to ensure that the VSAT network and the PSPDN can be connected. b) Connection quality recommendations (see clause 6): Connection quality recommendations are characteristics that contribute to maintaining a desirable quality of service and a uniform approach with regard to certain interfacing aspects@ addressing and facilities. The inability to meet the recommendations does not@ by itself@ prevent the equipment being considered as compliant with this ETS. Additional informative elements are provided in annex A.
