Introduction
The Multi-Rate DDS CSU/DSU is a cost-effective DDS
CSU/DSU that allows connecting your computer or other data
terminal equipment directly to the digital network without any
network access device. The unit transfers data at up to 64 kbps in
point-to-point or multipoint applications. It also accepts line rates
ranging from 2.4 to 64 kbps and performs
asynchronous-to-synchronous conversions.
The Multi-Rate DDS CSU/DSU is powered by an external wall
mount power supply. Easy configuration and setup is done using
DIP switches. The Multi-Rate DDS CSU/DSU can intelligently
respond to V.54 loopbacks initiated from the central office or
other equipment.
