- Module unit
Application
The HC-M106B DDF digital distribution frame is designed for use in machine rooms as a distribution device that operates between digital multiplex equipment or between digital multiplex equipment and program controlled exchange devices. The transmission impedance of the distribution frame is 75Ω, and the transmission rate is between 2Mbit/s~155Mbit/s. These units provide dispatching, transferring, monitoring, and many other functions for the digital signal of the circuit group.
