PRODUCT INFORMATION
ADSL24AE
AT-TN-140 24-PorT ADSL2+ ChANNeL UNiT (ANNex A)
The ADSL24AE (annex A) is a 24-port ADSL2+ channel unit for
the Allied Telesis iMAP and has been designed to meet the most
demanding broadband and IP Triple Play applications.
Uncompromising ADSL
Performance for Demanding
Applications
The ADSL24 channel unit'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 (VoD), 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 with 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.
Performance You Can Depend on

providers can maximize real world
downstream rates and DSL reach when
they use the ADSL24AE incorporating
our patent-pending optimized
interconnect system. This unique system
maximizes both revenue and subscriber
satisfaction.
A complete 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.
