The BroadmoreÆ 500 offers a uniquely economical means of provisioning common TDM and serial data circuits

directly from an ATM network without incurring the costs of large, full-featured ATM core switches. Its simple

ATM circuit provisioning replaces the complexities of configuring and managing SONET and Digital Crossconnect

Systems (DCS). ATM conversion is accomplished by using standards-based ATM Circuit Emulation

Service (CES) with support for both Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs).

Data circuits with speeds from 75 bps to 52 Mbps can be transported across the ATM core with the full benefits

and efficiencies of a converged voice and data access network.
 

The Broadmore 500 packs a lot of TDM-to-ATM aggregation power into just four rack units (RU) of space. Using

traditional equipment, the same power would require the equivalent of a 3:1:0 DCS for NxDS0 grooming, a

SONET Terminal for T1 and DS3 electrical distribution, a channel bank for low-speed serial links, and possibly a

router for tunneling high-speed serial linksówhich means more capex and opex costs across the board.

The Broadmore 500 is an ideal access POP aggregator or a circuit grooming front-end for ATM core switches. It

grooms just those service revenue-carrying TDM circuits onto the ATM core network, rather than transporting

partially filled fractional T1 and DS3 circuits. Serial data circuits that would normally be carried with DS1 or

DS3 granularity can now be transported at their native bit rates, saving considerable bandwidth on the core

network. Many of these grooming and concentration functions are only present in network locations where the

high cost of DCS equipment can be justified.

By using the Broadmore 500 for ATM conversion, networks enjoy the added benefits and efficiencies of ATM,

including end-to-end circuit test capabilities, automatic SVC rerouting for disaster recovery, and better overall

network bandwidth utilization. The Broadmore 500 expands ATM deployment options, letting service providers

deploy the TDM services they need with the features they want ñ without incurring the large upfront equipment

costs commonplace with traditional TDM equipment.

Recent release enhancements have extended Broadmore flexibility by providing additional command security

including user authentication, audit trails, session privacy and SNMP community strings. With an optional

feature, the latest stringent government security requirements are supported, including RSA SecurIDÆ user

authentication and SecSH network and management security.
