product information
The Allied Telesis ADSL24A is a 24-port ADSL2+ iMAP service module designed
to meet the most demanding broadband and IP Triple Play applications. The
Gigabit Ethernet backplane link ensures that all 24 ports will receive the maximum
of 26Mbps per port without over subscription. 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.
uncompromising ADSL
Performance for Demanding
Applications
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.
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 ADSL24A 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.
