M/HDSL Overview
Hotwiret 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/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 at 128 kbps, with distances exceeding 21,000 feet (6.9 km) on
24 gauge (.5 mm) cable delivered at 2.048 Mbps.
Hotwire M/HDSL units are equipped with an automatic configuration capability
that reduces the M/HDSL 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/HDSL units can also be
configured at fixed line speeds.
