Embodiment Construction
[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose, the following describes in detail the main control board switching method for enhancing the management of the extended subrack in the SDH equipment proposed by the present invention in conjunction with the accompanying drawings and preferred embodiments. The description is as follows.
[0019] The main subrack and the extension subrack in the network element node of the optical transmission system in the SDH equipment described in the specific embodiment of the present invention are as follows: figure 1 As shown, an SDH equipment optical transmission system network element node includes a main subrack and an extended subrack. The main control board on the main subrack is connected to the interface board on the extended subrack through the communication port. There is a bus connection on the backplane of the main subrack, only the two slots in the...

The invention discloses a method for switching a main control panel to improve the management of an expanding subsupport in an SDH device, which switches the main control panel on the prior hardware based on the connection state of a communication port. The method comprises the following: step one, electrically running a flow on the main control panel; step two, processing the flow at certain time by the main control panel; step three, processing a flow of the communication port by a spare panel; step four, repeating the step two and the step three, if the expanding subsupport is always in the detached state. Through the steps, the switching based on the connection state of the communication port can be realized simply and conveniently, thereby improving the management to the expanding subsupport. The method is realized through software, has low developing cost and strong expandability of function, and improves the reliability of network element nodes of the SDH device containing the expanding subsupport.
Description
technical field [0001] The present invention relates to the field of optical transmission of synchronous digital hierarchy (Synchronous Digital Hierarchy, hereinafter referred to as SDH) equipment, in particular to a main control board switching method for managing extended subracks in SDH equipment. Background technique [0002] Usually, there is only one main subrack in an SDH equipment optical transmission system network element node. In the main control board 1+1 hot backup system without extended subracks, the switching between the active main control board (referred to as the main control board) and the standby main control board (referred to as the standby board) is based on the LAY of the main control board. , Ready, heartbeat and other basic states, where LAY means that the main control board is inserted into the slot, that is, in place; Ready means the state of the main control board initialization is completed; heartbeat means the state of the main control board w...
