scope:
This standard specification using SDL representation, the circuit-switched call control procedures of the Digital Subscriber Signalling one (DSS1) as specified in $5 of ETS T/S 46-30[1].
In order to describe the point-to-multipoint operation of the protocol, the concept of a "global" process running in parallel with a number of "individual" (dynamic) processes in the network side has been introduced. This approach, and the associated definition of internal primitives is intended to provide a coherent description of the protocol and does not constrain implementations. The text description in $5 of ETS T/S 46-30 [1] is definitive.
