TDM SDSL Units

TDM SDSL Overview

1

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. Hotwire 2-wire TDM SDSL products transmit data over 14,000 feet (4.6 km) at rates up to 2.048 Mbps.

Hotwire products support autorate. Units first synchronize to the highest line rate that the 2-wire loop supports, then automatically configures the unit to the highest multiple of 64 Kbps supported by that line rate. Eight line rates are available. At all rates, an 8 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.
