  • HC-M106A 6-system digital distribution frame
  • HC-M106A1 12-system digital distribution frame

Application
The HC-A DDF digital distribution frame is installed in machine rooms as a distribution center between multiplex digital equipment or between digital multiplex equipment and program controlled exchange devices. The transmission impedance of the frame is 75Ω, while the transmission rate is below 155Mbit/s. The distribution unit provides dispatching, transferring, monitoring, and other functions for digital signals of the circuit group installation.

Features
1. The digital distribution frame is a modular structure with flexible configuration and installation options.
2. The frame is made of aluminum alloy profile or high quality cold rolled steel plate, with the surface treated by electrostatic spray.
3. The distribution frame is a semi-open structure, inside there is spacious wiring space, so that the cabling lines are clear and easy to handle.
4. Fast wiring installation
5. With gold plated coaxial connector, the contact resistance is low and the connection is reliable.
6. The digital distribution frames can be installed side by side, and the left and right between the frames are equipped with a coil line.
7. Two frames can be installed back to back and adjusted front and back.
8. With test port, it can be tested online, for convenient and flexible monitoring and maintenance.
9. HC-M106A1 uses new high density unit body with capacity twice that of the HC-M106A.
