AT-TN121-A 24 Port ADSL2+ Service Module (Annex A)

Allied Telesis’ iMAP family of integrated

Multiservice Access Platforms

Uncompromising ADSL

Performance for Demanding

Applications

The ADSL24 (Annex A) is a 24 port ADSL2+

service module for the Allied Telesis iMAP and

has been designed to meet the most

demanding broadband and

Triple Play

applications.The card’s Gigabit Ethernet

backplane link ensures that all 24 ports will

receivethe maximum of 26Mbps per port

without oversubscription. At the heart of the

card is a wirespeed Ethernet switch that is

designed for the most demanding traffic

applications: IP Multicast Video,Video on

Demand, voice, and data.

Each of the 24 subscriber ports can

simultaneously support any of the standard

ADSL modes - ADSL2+, G.DMT, S=1/2, or

T1.413 - on a per port basis. A powerful DSP

implements all ADSL algorithms and allows

future and emerging ADSL2+ features to be

added through simple software upgrades.

In ADSL2+ mode, a subscriber port can deliver

up to 26Mbps of downstream bandwidth -

enough to supportup to fiveset-top boxes of

standard digital video - plus headroom for VoIP

and data traffic.Traffic priority can be

differentiated by service type so that VoIP,

video, and data can be prioritized from a single

portbased on your business needs.

Performance You Can Depend On

Allied Telesis is the only broadband access

vendor that provides a complete end to end

ADSL solution. Service Providers can maximize

real world downstream rates and DSL reach

when they use the ADSL24 incorporating our

patent pending optimized interconnect system.

This unique system maximizes both revenue

and subscriber satisfaction.

Acomplete set of management counters

monitor ADSL performance at each end of the

link. Every performance monitor counter can be

assigned a threshold that will generate an alarm

if the threshold is exceeded.

Part of Allied Telesis’ IP Broadband

Access Family

Whether it is broadband ADSL2+, FTTH, POTS

or T1/E1 circuits, the iMAP family is the ideal

platform for last mile service delivery.The

ADSL24 (Annex A) line card can be used with

any of the iMAP family of carrier grade, IP

Multiservice Access platforms:

•iMAP 9700 (9RU, 17 service slots)

•iMAP 9400 (3RU, 7 service slots)

•MiniMAP 9100 (1RU, 3 service slots)

Provisioning, management, and diagnostics of

subscriber ports of subscriber ports can be

accomplished from either the iMAP command

line interface or the NMS.

The ADSL24 (Annex A) has been designed to

survivethe most rugged environmental

conditions. It can be confidently deployed in

either a central office or in outdoor enclosures

withstanding extremes of heat, cold, and light

exposure.

Allied T

elesis provides a large portfolio of FTTx,

Ethernet and xDSL transport and access

equipment. In addition, Allied Telesis provides a

complete set of xDSL and FTTx CPE solutions

in the form of Multi-Service Gateways, Layer 2/

Layer 3 switches, routers or media converters

to terminate the broadband link.
