About the Hotwire 8784 
Termination Unit
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.
