Multiservice Bandwidth Manager Enhancements

MainStreet Frame Relay

The Alcatel 3600 MainStreet Multiservice Bandwidth Manager

and the Alcatel 3600 MainStreet Multiservice Bandwidth

Manager platforms offer extensive frame relay services. With

the simple and cost-effective addition of a frame relay engine

(FRE), packet engine (PE) or frame relay switch with Subrate

Interface Module (FRS/SRIM) card, an Alcatel 3600/Alcatel

3600 MainStreet node provides comprehensive frame relay

switching capabilities.

MainStreet Frame Relay is a proven service used extensively

in public and enterprise networks throughout the world. It

can be used effectively in large or small networks that deploy

frame relay alone, or in combination with leased line, X.25

and ATM services. Based on a modular architecture, up to

64 FRE and/or PE cards can be connected across the 100 Mb/s

FASTbus to create a high capacity node that is capable of

switching 120,000 fps.

MainStreet Frame Relay services include X.25/frame

relay/ATM network and service interworking capabilities,

subrate frame relay switching, and value-added service

capabilities, such as VoFR with QoS, packet fragmentation

and reassembly, and DLCI multiplexing.

T E C H N I C A L I N F O R M AT I O N G U I D E

An Alcatel 3600 MainStreet Multiservice Bandwidth Manager

or Alcatel 3600 MainStreet Multiservice Bandwidth Manager

system that includes frame relay seamlessly interworks with

the Alcatel 7470 MSP and the Alcatel 7670 RSP to provide

an end-to-end frame relay solution — from the customer

premises to the network core. These platforms are fully

managed by the Alcatel 5620 NM allowing service providers

to manage the multiservice environment from a single

platform and console. New facilities can be added in seconds,

rather than weeks, as more subscribers request service.

MainStreet ATM Service

The MainStreet ATM Service cards provide ATM service

adaptation and inverse multiplexing over ATM (IMA) for the

Alcatel 3600/Alcatel 3600 MainStreet Multiservice Bandwidth

Managers. Installed in any universal card slot (UCS), the ATM

Service cards adapt the rich variety of Alcatel 3600/Alcatel

3600 MainStreet Multiservice Bandwidth Managers supported

services to ATM cells for transmission over an ATM network.

The ATM Service cards support AAL1 and AAL5 adaptation.

The circuit emulation service (CES) adapts constant bit rate

(CBR) traffic (n*64 kb/s) to AAL1 virtual circuits (VCs). The

HDLC service adapts HDLC-formatted traffic into AAL5 VCs.

The card has four E1 or T1 interfaces (physical ports). Each

port provides a user network interface (UNI) to an ATM net-

work and can function as an independent network link, or can

be assigned to a logical IMA port for combined transmission.

Extending broadband ATM benefits to the Alcatel 3600/Alcatel

3600 MainStreet Multiservice Bandwidth Managers, the ATM

Services Card allows corporate networks to exploit rate

differentials that favor ATM. The card’s IMA capability is also

a tremendous benefit where WAN connectivity requirements

exceed E1/T1 capacity. The ATM Service card is optimized to

support a single ATM aggregate comprised of one to four

inverse multiplexed E1/T1 links.

A L C AT E L 2 1 >

MainStreet Business Access Portfolio

Installing the ATM Services Card in Alcatel 3600/Alcatel

3600 MainStreet Multiservice Bandwidth Managers increases

network efficiencies, as operators manage only one logical

“pipe” ranging from 1.5 Mb/s to 8 Mb/s, instead of parallel,

discrete E1/T1 links.

By using the Alcatel 3600/Alcatel 3600 MainStreet

Multiservice Bandwidth Managers as close to the customer

location as possible to adapt established and proven services

to broadband, service providers are able to increase access

to their ATM core infrastructures. The n* E1/T1 aggregate

accommodates an infinite mixture of traffic types, and the

ATM quality of service parameters ensure each traffic type

is given and achieves the required service level.

MainStreet X.25 Service

The Alcatel MainStreet X.25 Service is a high-performance,

feature-rich, standards-compliant X.25 product that is suitable

for public switched data, large service providers, and

corporate data networks. The system architecture enables

advanced protocol encapsulation and conversion features.

These include X.25/FR/ATM network and service inter-

working, all of which are supported on a single platform.

Alcatel MainStreet X.25 Service offers the following

key benefits:

>

Flexibility – the most flexible X.25 product available,

offering seamless interworking with all other standards-

based X.25 products and networks

>

Versatility – supports X.25 and frame relay services

simultaneously and interchangeably on the same card;

ports can be reconfigured through software as service

needs change

>

Simplicity – unsurpassed installation, operation, using

full graphical user interface (GUI)-based network

management and software-driven configuration

> 2 2 A L C AT E L

>

Scalability – each service — X.25, frame relay, TDM,

integrated services digital network (ISDN), and ATM —

can be individually introduced and scaled to cost-effectively

meet the requirements of many network applications,

reducing initial investment risk while maintaining linear

cost per port as application demands increase

>

Reduced Costs – significant cost savings can be achieved

through consolidation of X.25 and other services on an

integrated and fully managed MainStreet network
