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 crossing processing unit and a branch processing unit. The method of the low-order channel subnetwork connection protection device includes the following steps: A. a main control board sends the calculated crossing protection relationship to the time division crossing processing unit; B. according to the received crossing protection relationship, the time division crossing processing unit configures chips; C. the time division crossing processing unit detects the alarms of 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 crossing 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...
