This Annex contains the description of the signalling procedures
described in this Recommendation in the form of state transition diagrams
according to the CCITT Specification and Description Language (SDL). In 
order to facilitate functional description, the ISDN User Part (ISDN\(hyUP) 
signalling procedure is divided into main functional blocks, as shown in 
Figure\ B\(hy1/Q.764. These blocks are as follows: 
.RT
.LP
	1)
	\fISignalling procedure control (SPRC)\fR 
.LP
	SPRC provides procedures for sending ISDN\(hyUP messages to
Level 3 (SCCP or MTP) and distributing received messages to the other ISDN\(hyUP 
functional blocks. 
.LP
	2)
	\fICall processing control (CPC)\fR 
.LP
	CPC provides call control procedures for realizing basic
circuit switched service according to user's request.
.LP
	3)
	\fICircuit supervision control (CSC)\fR 
.LP
	 CSC provides procedures for circuit supervision control for maintenance 
purpose and for recovery from abnormal situation. 
.sp 2P
.LP
B.2
	\fIDrafting convention\fR 
.sp 1P
.RT
.LP
	a)
	 External inputs and outputs are used for interactions with a remote exchange 
and interaction between SPRC and the other functional blocks. Internal 
inputs and outputs are used for interactions within each functional 
block, e.g.,\ to indicate control of time\(hyout. For these interactions, 
input 
and output symbols are used as shown in Figure\ B\(hy2/Q.764.
.LP
	b)
	Inputs and outputs symbols contain as part of their name
acronyms of their source and destination functional block names with an 
arrow in between, e.g.,\ Blocking BLS\ \(ra\ CPC. 
.LP
	c)
	A simple example of SDL diagram according to the above
conventions is shown in Figure\ B\(hy3/Q.764.

The ISDN\(hyUP SDL diagrams are described based on the three\(hyblocks 
approach. In this approach, call control, which provides 
signalling\(hyindependent functions such as connect\(hythrough, circuit 
selection and digits analysis, is outside the ISDN\(hyUP. These functions 
are described only in \(sc\(sc\ 1\(hy3. The ISDN\(hyUP diagrams are provided
