INFRASTRUCTURE

.

IMA is an ATM Forum specification that provides a

cost-effective and scalable alternative to T3/E3 services by

offering service providers and enterprise customers the

ability to leverage widely available T1 services over ATM,

and interoperate with other vendors’ standards-based

equipment. Multiport T1/E1 IMA can provide organizations

with highly desired

fractional T3/E3 bandwidth

connectivity so critical in

situations where DS3 or

OC-3 fiber communications

links are either cost

prohibitive or unavailable.

Enterprise customers

can take advantage of IMA

bandwidth flexibility on the

Cisco 7200 series routers to

provide an affordable

LAN-to-WAN connectivity

solution in the regional

office or large branch office,

and wherever they deploy ATM edge applications. The

greater overall bandwidth, and the incremental nature in

which bandwidth capacity can be added as needed, support

the rapidly growing multiservice needs of today’s enterprise.

Service providers can deliver critical integrated ATM

services combining voice, video, and data with ATM QoS

features. With multiport IMA deployed as customer premises

equipment (CPE) edge equipment, network service providers

can deliver unmatched flexibility and a wide range of services

to their customers.
