This standard specifies a set of protocols to provide the function defined below. The requirements placed on an end system in this prestandard are solely those necessary for operation of the protocol set specified. It does not specify total end system capability. This prestandard is defined in terms of the use of a D channel for communications between end systems using the "no notification class". No distinction is made in this prestandard between the use of a D channel provided by a Basic interface and the use f a D channel provided by a Primary Rate interface. This prestandard specifies: a) the provision of the OSI Connection-mode Transport Service ISO 8072 between an end system (the "reference end system") attached to the same ISDN, or is indirectly accessible through the provided network service; b) the provision of the OSI Connection-mode Network Service (ISO 8348) between the reference end system and the compatible end system. This prestandard used the X.25 PLP operating in the D channel to convey all the elements, of all three phases, of the OSI CONS. In this access case, no Q 931 or prETS 300102 call control message are needed at any point before or after the establishment of a virtual call or during the data transfer phase on an established virtual call. The use of PVC is not with the scope of this prestandard because the OSI CONS is provided only by the use of Virtual Calls.
