Embodiment Construction
[0043] The core of the present invention is that the switching network boards between the frames of the communication system are interconnected by a cross physical medium, and the service transmission mode of double transmission and double reception is adopted between the frames, so as to ensure the reliability of the service transmission between the frames in the communication system , and can reduce the complexity of system implementation.
[0044] The present invention firstly provides a system for inter-frame interconnection in a communication system, the structure of which is as follows image 3 shown, including:
[0045] Each frame of the communication system includes two switching network boards, usually the main switching network board and the standby switching network board. In the present invention, it is necessary to adopt cross physical media interconnection between the switching network boards between the frames; The use of crossover physical media interconnectio...
