AT-TN121-A 24 Port ADSL2+ Service Module (Annex A)
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
receive the 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 support up to five set-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
port based on your business needs.
