Embodiment Construction

[0023] When realizing the protection of the low-order path from the optical board to the tributary board, when the hardware resources are limited or the bandwidth capacity is insufficient, the subnet connection protection of the low-order path on the tributary processing unit cannot meet the requirements, and the time-division crossover Under the condition that the capacity of the processing unit is sufficient, the present invention changes the traditional implementation method and implements the subnet connection protection in the time division cross processing unit, which can solve the problem well.

[0024] The SDH transmission equipment in the present invention includes a main subrack and an extension subrack, the main subrack and the extension subrack are two separate subracks of the same network element, and the extension subrack is an additional subrack relative to the main subrack a subrack.

[0025] Usually, the extension subrack is required to be able to add and drop...

Abstract

The invention provides a low-order channel subnetwork connection protection device and a method thereof. The low-order channel subnetwork connection protection device comprises a light panel, a time division cross processing unit and a branch processing unit. The method includes the following steps: A. a main control board sends the calculated cross protection relationship to the time division cross processing unit; B. according to the received cross protection relationship, the time division cross processing unit configures chips; C. the time division cross processing unit detects the alarmsof every channel, and according to the current signal quality of the active-standby channel, every protection group implements protection and switching. The low-order channel subnetwork connection protection device and the method thereof have the advantages of easy realization of the protection of the low-order channel from light panel cross to a branch board and low cost.

Description

technical field [0001] The present invention relates to a device and method for realizing low-order channel subnet connection protection, in particular to a device and method for realizing low-cost channel subnet connection protection proposed in the optical synchronous digital transmission network (SynchronosDigitalHierarchy, referred to as SDH) transmission field. method. Background technique [0002] Subnet connection protection includes high-order channels such as vc4 and low-order channels such as vc11 and vc12. It belongs to linear VC path protection and is a special protection mechanism that can be used in any physical topology. Such as figure 1 As shown, the optical board is the line processing unit in the SDH equipment, and the tributary board is the tributary processing unit in the SDH equipment. The low-order subnet connection protection of SDH equipment generally includes the protection of the low-order channel from the optical board to the optical board, and t...
