Patent Description:
A distribution frame is a device used for terminal user lines or trunk lines and capable of deploying and connecting them. The distribution frame is the most important assembly in the management subsystem, and is the hub to realize the cross connection between the vertical trunk line and horizontal cabling subsystems. A modular distribution frame is applicable to the mounting and fixing of network modules in the middle of the network device. A network cable from a switch is connected to a network cable from a crystal head to a working side through the network modules mounted and fixed in the distribution frame.

The distribution frame is usually mounted on a cabinet, a multimedia box, a wall or a desktop. In the application of the distribution frame, the application scenarios are more and more diversified. Nowadays, modular distribution frames on the market are thick and ugly, and semi-closed structures cannot meet the relevant requirements of dust prevention and moisture prevention, and are not easy to mount. Therefore, it is necessary to design a new closed modular distribution frame which is convenient to mount and operate to meet the needs of the market. <CIT> is directed to a communication system that enables transmitting control signals between communication devices connected with a communication cable. The control signals are either to activate a visual indicator associated with the second port or to request a unique identification number and the signals are transmitted without changing the voltage polarity between the control wires.
