Abstract

The invention relates to a multi-service full-granularity crossed intelligent access method and system based on SDH and MSTP technologies, and relates to the fields of communication transmission network access and network control and management. In an SDH multiplexing structure, multi-service SDH full crossing of 64kbit / s is realized in a byte synchronous mapping mode of a 2048kbit / s branch; an automatic switched optical network is introduced into an MSTP technology based full-granularity service crossing system; and the realized multi-service SDH full crossing of 64kbit / s is integrated with the MSTP technology based full-granularity service crossing system into which the automatic switched optical network is introduced in an intelligent network management system. According to the system and method, management via a unified network management platform is supported, end-to-end link managing and setting can be carried out conveniently, management and maintenance during operation of equipment are supported rapidly and effectively, and a transmission channel is controllable, maintainable and manageable.

Description

technical field [0001] The invention relates to the fields of communication transmission network access and network control management. Background technique [0002] It has been more than 20 years since the SDH transmission technology was born in the 1990s. It has become the basis of modern transmission networks and is widely used in military communication networks. SDH stipulates a set of international standards, including multiplexing structure and networking principles, making the transmission network a flexible, compatible, high-reliability, intelligent management network that can implement centralized control. Judging from the application requirements of the current private communication network, it has the characteristics of high service security and reliability, scattered service access points, diverse signal interface requirements, and complex service access rates, ranging from a low rate of 64kbit / s to a high rate of 2Mbit / s or 155Mbit / s and other granular require...
