The DSS1 network layer (Layer 3) is responsible for establishing, maintaining and clearing circuit-switched traffic channels between customers and ISDN local exchanges. DSS1 Layer 3 can be described in terms of its formats and the procedures, defining the logical sequence of events, in meeting customer requirements. Section 9.2 describes the principles of the format technique and Section 9.3 gives examples of messages to illustrate the principles. The basic procedures for establishing circuit-switched calls are described in Section 9.4 and the procedures for clearing such calls are described in Section 9.5. DSS1 Layer 3 includes features additional to those necessary for establishing and clearing calls and these features are outlined in Section 9.6. DSS1 Layer 3 is required to provide access to packet-data facilities and the means of achieving this requirement are described in Section 9.7. Section 9.8 covers the invocation and transfer of user-to-user signalling over the access signalling channel. Finally, whilst the DSS1 network layer does not specify detailed procedures for the control of supplementary services, three generic procedures are outlined in Section 9.9.
