Signaling Control
SVC connections provided by the ATM Switch are prepared by a protocol called signaling that establishes and releases SVCs.
The signaling protocol is used by the calling terminal to notify the network of the destination of the established SVC, communication band, and traffic quality.
The signaling protocols supported by the ATM Switch are as follows:
■
■ATM Forum UNI 3.0 based on Q.SAAL1 (SSCOP) of
■ATM Forum UNI 3.1
■ATM Forum UNI 4.0
The addresses that can be used for signaling are:
■Address format E.164.
■NSAP incorporated ATM private network address defined by ATM Forum.
■Besides UNI, the ATM Switch also supports routing function and signaling function conforming to ATM Forum PNNI 1.0. Consequently, a signaling request may be routed through a network composed of more than one switch.
■Control layer AAL5 (ATM Adaptation Layer 5) called "C plane" is used to convey the signaling request.
Figure 5-2 shows the protocol stack of the C plane.
