Embodiment Construction

[0014] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0015] According to an embodiment of the present invention, a method for transmitting synchronization state information is provided, including: a clock board sends the synchronization state information to a service board through Ethernet packet exchange.

[0016] In related technologies, SSM information is transmitted between the clock board and the service board through hardware control. In this embodiment, because the synchronous state information is sent to the service board through Ethernet message exchange, which is a software control method, the implementation is simple, and the production and maintenance costs are reduced.

[0017] Preferably, the clock board shares the existing Etherne...

Abstract

A method, system and clock board for transmitting synchronization status message are provided by the present invention. Said method includes: a clock board transmits a synchronization status message to a service board in an Ethernet message exchange manner. The present invention can be implemented simply, thus the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, a system and a clock board for transmitting synchronization state information. Background technique [0002] In Synchronous Digital Communication Network (SDH / SONET), the Synchronization State Information (SSM) is an important guarantee for the clock unit to realize clock networking protection, and the protection switching of the clock source is realized through the SSM. The real-time transmission of SSM between the clock board and the service board is an important part of clock source protection switching and clock network protection, which directly affects whether the phase-locked loop tracks whether the high-quality clock signal and network protection function, and then affects the entire network The status of the clock signal, and the normal operation of the entire SDH network. [0003] The inventors found that the current technology transmits SSM information between the ...
