M/SDSL Overview

Hotwire Multirate/Symmetrical 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 can transport at full or fractional payload rates over a 2-wire, full-duplex circuit over varying distances based on the conditions of the 2-wire loop. Examples include support for router, multiplexer and PBX connections at 128 kbps, with distances exceeding 29,000 feet (8.9 km) on

24 gauge (.5 mm) cable, or up to 15,000 feet (4.6 km) delivered at 2.048 Mbps on 24 gauge (.5 mm) cable.

Hotwire M/SDSL is equipped with an automatic configuration capability that reduces the M/SDSL installation process to a simple plug and play mode. Simply connecting the units to the line automatically configures the customer for the maximum data rate supported by the local loop. M/SDSL units can also be configured at fixed line speeds to achieve maximum distances.
