M/SDSL and HDSL2 Overview

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 M/SDSL products transmit data over 14,000 feet (4.6 km) at rates up to 2.048 Mbps.

Hotwire High-bit-rate DSL second generation (HDSL2) products transmit data up to 12,000 feet (3.9 km) at up to 1.544 Mbps.

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.
