Describes a network-infernal Interface for the Provision of JSDN packet-mode services. The term ISDN packet mode Services is defined in such a way as to include both case B (ISDN Packet Mode Bearer Services (PMBS)), and case A (PSPDN services), see ETS 300 007 [20]. This specification shall be used if a specific implementation alternative for the Provision of these services is used in an ISDN. The implementation alternatives and the exact location of the Interface are described in the following paragraphs.
