LAN-ATM switches can be directly

interconnected via ATMSpeed

modules, lowering total equipment

costs by eliminating the need for

separate ATM switches at the core

of the network. As networks grow

and powerful Centillion 1000 multi-

service switches are deployed at the

network core, existing Centillion

LAN-ATM switches are readily

redeployed to support wiring closets

and/or server farms.

APPLICATIONS

Centillion LAN-ATM switching solutions

offer a single, consistent architecture

across all facets of the network. This

uniﬁed approach ensures maximum

network availability, efﬁciency, and

interoperability across the full range

of ATM applications, and minimizes

the need for additional user training.

The size of the network governs both

switch selection and the location of

switch deployment. In medium- to

large-sized networks, the Centillion

100 and System 5000BH switches are

ideal for network center installations.

In the largest enterprise environments,

these switches can be used for high-

density wiring closet installations,

with high-speed riser connections to

Centillion 1000 multiservice switches

located in the network center.

And in networks of all sizes, the

Centillion 50 switch is ideal for

deployment in lower-density wiring

closets or workgroup environments.

Enterprise Network

Center Applications

The Centillion 100 and System 5000

switches are both well-suited for

deployment in medium-to-large

network centers and wiring closets.

Both platforms are ideal for deployment

in networks where multiple switches

can be interconnected via PNNI

and/or IISP to build a scalable,

high-performance backbone network.

Single-mode and multimode ﬁber,

UTP, DS3, and E3 connectivity is

supported for maximum ﬂexibility,

enabling switches to be installed in

network centers or other locations

across the campus backbone

(see Figure 4).
