Problems solved by technology

[0006] Since the slot number of the board is obtained by reading the slot number of the slot on the backplane, if a certain slot number signal of the backplane fails, or the interface device for reading the slot number of the board fails, then The board will read the wrong slot number, which will lead to abnormal or paralyzed system communication

Embodiment Construction

[0031] In order to make the purpose, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Please refer to Fig. 1, which is a schematic diagram of board connection provided by the embodiment of the present invention. There are a central single board (master) 101 and a service single board 102 in the machine frame, and the service single board 102 is inserted in different slots on the backplane. Single board 101 to each business single board 102 has independent star data channel, therefore, each business single board 102 has mutually independent ports on central single board 101, and, the slot number of business single board 102 and central unit The corresponding relationship of the port numbers of the board 101 has been fixed through PCB wiring, and is stored in the central single board 101 as system configuration in...

Abstract

The invention discloses an allocation method for veneer groove location numbers and comprises the following steps that a central veneer receives address request messages sent by a business veneer; the central veneer allocates groove location numbers for the business veneer according to the corresponding relationships of preset interface numbers, groove location numbers and the interface numbers of the received address request messages; the central veneer returns and carries responding messages of the groove location numbers to the business veneer. The invention also correspondingly provides a central veneer, a business veneer and a communication system. The adoption of the technical proposal provided by the embodiment of the invention ensures the accuracy of the allocation of the groove location numbers and the stability of the communication system.

Description

technical field [0001] The invention relates to the field of communication, in particular to a single board slot number configuration method, a central single board, a service single board, and a communication system. Background technique [0002] In the communication system architecture, a single board is generally installed on the backplane of the chassis as a basic physical entity, and the chassis is placed in the corresponding cabinet. Multiple single boards as subsystems work together to realize the functions of the entire communication system. [0003] When the system works normally, in addition to the information interaction between the boards and the external network, there is also the transmission of data, signaling, and operation and maintenance information between the boards, and the information transmission between the boards must be based on known Based on information such as the physical location of these boards. [0004] The physical position of the board is ...
