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.
