Embodiment Construction

[0027] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the embodiments of the present invention will be further described in conjunction with specific drawings.

[0028] A communication method of the present invention is applied to the main control panel of an EPON device to communicate with its subsidiary business panel, such as the communication between the FP6508 device and the FPGA or CPLD of the EPON business card, where the interface of the communication protocol is defined as :

[0029] The communication bus for data communication includes a data valid signal line, a communication clock signal line and a two-way data signal line. Correspondingly, the communication bus protocol includes a data valid signal, a communication clock signal and a two-way data signal line.

[0030] figure 1 It is a sequence diagram of the operation of the communication bus in the embodiment of the present invention, such as...

Abstract

The invention relates to the field of communication electronics, in particular to a communication bus protocol and a system comprising the same. According to the communication bus protocol and the system comprising the same, a management channel is set and a communication bus protocol of the management channel is defined by using idle IO (Input / Output) on a CPU (Central Processing Unit) of a main control panel of EPON (Ethernet Passive Optical Network) equipment and an FPGA (Field Programmable Gate Array) of the main control panel, therefore the problem that no other bus interface resources is used as the management channel when the bus interface resources of the CPU on the main control panel are limited is solved, and the purpose of effectively supervising and managing a business panel by the main control panel is achieved.

Description

Technical field [0001] The invention relates to the field of communication electronics, in particular to a communication method and system. Background technique [0002] At present, in Ethernet Passive Optical Network (EPON) equipment, the main control board needs to communicate with each of its affiliated service boards, and it also needs to monitor and manage the status of all service boards. It is necessary to set up a management channel from the CPU of the main control disk to connect each service disk to realize the corresponding management function. However, when the bus interface resources of the CPU on the main control disk are limited, other bus interface resources cannot be used as management channels, which affects the supervision and management of the service disk by the main control disk. Summary of the invention [0003] In order to solve the above problems, we now provide a technical solution aimed at solving the problem of being unable to set up a management chann...
