M/SDSL and M/HDSL Overview
Hotwire Multirate Symmetric Digital Subscriber Line (M/SDSL) and Multirate
High-bit-rate Digital Subscriber Line (M/HDSL) 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 data 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 on 24 gauge (.5 mm) cable at greater than 14,000 feet (4.6 km)
delivered at up to 2.048 Mbps (depending on model).
Hotwire M/HDSL products can transport at full 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) delivered at
up to 2.048 Mbps (depending on model).
Hotwire 79xx Standalone Termination Units are equipped with an automatic
configuration capability that reduces the 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. Units can also
be configured at fixed line speeds to achieve maximum distances.
