SIGNALLING Overview

The SmartSwitch 9500 supports all ATM Forum ratified specifications of the User-Network
Interface (UNI) as well as IISP and PNNI. UNI Signalling is used by ATM devices to set up
SVCs for traffic transport.

4.2.1 Stack Types

The SmartSwitch 9500 supports all ATM Forum Signalling Stack Types.
The SmartSwitch 9500 can support both User and Network side of UNI and IISP Signalling
stacks. These Signalling stacks are autoconfigured by ILMI 4.0 by default as described in
Chapter 3. Section 4.2.2 - Section 4.2.4 provide details on how these stacks may be statically
configured via the AToM MIB.
4.2.2 Configuration
Configuration of the Signalling stack can be done automatically via ILMI 4.0, or manually by
the user via the AToM MIB. In autoconfiguration, the two connected devices negotiate to the
highest supported UNI or NNI version. The necessary parameters are set up, and the
Signalling stack becomes operational. To configure the stack manually, refer to the
Section 4.2.3 and Section 4.2.4.
