Termination Unit
M/SDSL Overview
7900-A2-GB21-00
Hotwirer Multirate Symmetric Digital Subscriber Line (M/SDSL) products
maximize customer service areas by varying the DSL line rate. This ensures
symmetric DSL connectivity over a wide range of telephone line distances and
transmission line qualities.
Hotwire products support autorate. Units first synchronize to the highest line rate
that the 2-wire loop supports, and then automatically configure to the highest
multiple of 64 kbps supported by that line rate. Eight line rates are available. At all
rates, a 16 kbps management channel is available, which enables functions such
as firmware downloads to remote units. Units can also be configured manually to
full or fractional T1 or E1 rates.
Hotwire products transport data over a 2-wire (M/SDSL) full-duplex circuit over
varying distances based on the conditions of the loop. Using 24 AWG cable,
M/SDSL products have a loop reach greater than 14,000 feet (4.6 km) at
2.048 Mbps.
