Abstract

The invention discloses an updating method of optical synchronous digital transmitting network system for SDH network system, which comprises the following steps: 1. changing the updated low-speed optical interface at two ends of SDH network system into high-speed optical interface unit; 2. testing the back board bus velocity variation through crossing disposing unit connected with optical interface unit; modulating the distribution of time interval allocation on the low-speed bus business into the distribution on the high-speed bus according to the variation of back board bus speed automatically; 3. repeating the step 1 and step 2; changing the low-speed optical interface unit at two ends of network end into high-speed optical interface unit; 4. handing out network allocating information and protection information of allocation information of high-speed network for network equipment of the updated high-speed optical interface unit. The invention ensures the SDH equipment updating without influencing for business, which simplifies the updating course and shortens the updating time.

Description

technical field

[0001] The invention relates to a method for upgrading an optical synchronous digital transmission network system, in particular to a method for upgrading a low-rate SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy) optical transmission network system to a high-rate SDH optical transmission network system. Background technique

[0002] Existing optical transmission equipment can be upgraded from a low-rate system to a high-rate system through the design of a compatible backplane, and the subsequent development of a compatible board and related software. Since this upgrade process involves board replacement and software update, and the network protection function of the original system fails during the update process, it will cause the original normal running business to be interrupted, ranging from a few hours to a few days, resulting in network failures. Upgrades are expensive.

[0003] According to the patent No. 5,570,344 published by the...
