Method and system for acquiring in-place information of extended sub-frame by main sub-frame of SDH equipment

Abstract

The invention provides a method for acquiring in-place information of an extended sub-frame by a main sub-frame of SDH equipment. The method comprises the following steps that: after discovering that a condition led to the failure of the in-place information of the extended sub-frame is triggered, the main sub-frame sends a request order to the extended sub-frame to inquire the in-place information of the extended sub-frame; and the main sub-frame receives the in-place information reported by the extended sub-frame and stores the in-place information. In addition, the invention also provides a system for acquiring the in-place information of the extended sub-frame by the main sub-frame of the SDH equipment. The method and the system solve the problem that the main sub-frame cannot quicklyre-acquire the in-place information of the extended sub-frame when the state of a master control board is changed in the prior art, fast acquire the in-place information of an extended sub-frame veneer, and strengthen the management of the extended sub-frame by the main sub-frame.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for acquiring the presence information of an extended subrack by a main subrack of SDH equipment. Background technique [0002] At present, the SDH equipment of the optical transmission system usually needs to process services at the upper and lower levels, but due to the limitations of the main subrack on technical equipment, it is impossible to expand the capacity without limit, and considering the problem of cost, the extension subrack is generally used at this time To complete the expansion of the service processing capability of the main subrack. In a system including the main subrack and the extended subrack, the presence information of the single board of the extended subrack is reported to the main control board of the main subrack through the interface board of the extended subrack, thereby realizing the communication between the main subrack and the exten...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that when the status information of the extended subrack stored in the main subrack becomes invalid due to the change of the state of the main control board of the SDH equipment, the main subrack cannot quickly reacquire the status information of the extended subrack. This affects the working efficiency and reliability of SDH equipment, and proposes a method and system for the main subrack to quickly obtain the in-position information of the extended subrack through the active query of the main control board.
