Chapter 1. Overview
ATM Networks
The purpose of an ATM network is to set up connections between ATM user devices, the two end points
of a connection.
IBM ATM subsystems can be interconnected in order to build a local, privately owned and administered
ATM network called an ATM Campus Network.

Network Components
The terms used to describe the components of an ATM Campus Network are defined here:
ATM Campus Network One or more interconnected ATM peer groups.
This set of peer groups is controlled by one administrative domain and a single
private owner using one network access protocol (UNI).
ATM Peer Group One or more ATM switches interconnected by PNNI interfaces, and sharing the
same peer group identifier.
ATM User Device An end system that encapsulates data into ATM cells and forwards them to the
ATM subsystem across a UNI interface. Examples of ATM user devices are:
Servers and workstations equipped with ATM adapters
ATM concentrators or workstations equipped with ATM adapters
Routers with ATM adapters
LAN ATM bridges.
The Control Point passes the network prefix of an ATM address to attached end
systems using the Interim Local Management Interface (ILMI) protocol.
Network Interfaces
The following protocols are defined in ATM standards for use across the interfaces connecting the
components of an ATM campus network:
UNI Defines the interface between an ATM user device (such as a terminal, router, bridge, server,
workstation, or concentrator equipped with an ATM adapter) and the ATM network. The ATM
subsystem supports the Private UNI as defined by the ATM Forum UNI Specifications V3.0,
V3.1 and V4.0, as well as UNI for Public carriers.
IISP Defines the interface between two ATM switches belonging to different ATM routing domains.
In the current release, IISP switches are used to interconnect PNNI peer groups.
Operator intervention is required in order to define the addresses reachable over IISP links.
You can define multiple IISP connections between two different peer groups.
PNNI Defines the interface between ATM switches in the same peer group.
The PNNI interface supports networking functions without the need of operator intervention,
such as routing, node failure and node recovery, backup, and topology management.
You can define multiple PNNI connections between two ATM switches.
VOID Defines an interface between an ATM switch and a Wide Area Network (WAN) that is used to
carry a Virtual Path Connection (VPC). ILMI is not supported on VOID ports, however when a
VP tunnel is defined, signalling is supported through the VP.
AUTO The interface is automatically set according to that of the incoming signal, as detected by ILMI.
