TDM SDSL Overview

Hotwire Time Division Multiplexer Symmetric Digital Subscriber Line (TDM 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.

TDM SDSL termination units can transport data at full (1.544 Mbps) or fractional payload rates over a 4-wire, full-duplex circuit over varying distances based on the conditions of the 4-wire loop. Examples include support for router, multiplexer and PBX connections on 24 gauge (.5 mm) cable up to 21,000 feet (6.4 km).

The termination unit is equipped with an automatic configuration capability that reduces the installation process to a simple plug-and-play procedure. Simply connect the unit to the line and it automatically configures itself for the maximum data rate supported by the local loop. The unit can also be configured for fixed line speeds to achieve maximum distances.
