AT-TN-140-A 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.
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.
