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.
