3Com 6416SW manual ATM Cluster, Ssi, ATM User Device

ATM Subnetwork One or more ATM clusters interconnected using NNI interfaces.

An ATM subnetwork is identified by:

	The	first	9	bytes	of	the network	prefix,		which are the same for
	all	subnetworks		in a	Campus Network,		plus
	A 2-byte routing domain					numberRDN ), which(		is unique		within
	the	ATM Campus		Network.
ATM Cluster	One or	more	ATM	subsystems		interconnected		using	SSI	interfaces.

An ATM Cluster is identified by:

The	first	11	bytes	of the network prefix, which are the same for
all	clusters	in	an ATM	subnetwork, plus

A 1-byte ATM Cluster NumberACN ),( unique within the ATM subnetwork, which ranges from 0 to 255.

ATM Subsystem The components of the ATM subsystem in the hub include:

Integrated ATM Switch/Control module functions

Devices

connected

to

the

ATM

ports

ATM

media

modules

installed

ATM interfaces: user-to-network (UNI), switch-to-switch (SSI),

network-to-network (NNI).

An

ATM

Subsystem

is

identified

by:

The

first

12

bytes

of

the

network prefix, which are the same for

all

subsystems

in

a cluster,

plus

A 1-byte Hub

NumberHN ),

(unique

within the

ATM

Cluster,

which

ranges

from

0

to

255.

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.
