Embodiment Construction

[0074] The following are specific implementation methods for realizing the data service and SDH service hybrid converging device, and several typical methods embodying the technical solution of the present invention.

[0075] Please refer to FIG. 3 , which is a block diagram of a performance monitoring device for an SDH optical channel of a WDM network according to the present invention.

[0076] At the sending end, the data service and SDH service are respectively converted into a unified format, and then each data service channel and SDH service channel are coded, and then the data of each channel is aggregated into one high-speed data according to the configuration. Each data service channel supports bandwidth and priority settings during conversion. The data service format conversion module can allocate bandwidth according to channel reception and system priority requirements, and aggregate the data of each channel into the group channel as needed. ; At the receiving end, ...

Abstract

This invention discloses a mixed gathering method for data service and SDH service and its device characterizing that the device includes: a SDH service rate adaptive module receives signals of the SDH service channel and adapts velocities, a SDH service formation conversion module converts the SDH signals to a set unified format and sends it to a time slot exchange unit, the data service adaptive module receives data signals of a service channel and adapts the velocities, a format conversion module converts said data signals to a designed unified one and transmits it to the time slot exchange unit, which carries out time slot cross process to the converted SDH signals and data signals then to finish service gathering via a group of route adaptive units.

Description

technical field [0001] The present invention relates to a converging device for optical transmission equipment, in particular to a data service and SDH service hybrid converging device and converging method of WDM (Wavelength Division Multiplexing, wavelength division multiplexing) transmission equipment / system. Background technique [0002] With the continuous development of communication technology, people's demand for communication capacity continues to increase. People generally use aggregation technology to aggregate several low-speed services into one high-speed channel, which can save channel usage and increase system transmission capacity. Communication system unit cost. [0003] At the end of the 20th century, the existing communication equipment was mainly Synchronous Digital Hierarchy (SDH) equipment, and the business was mainly related to voice. With the development of network broadband technology, it is gradually developing into data business. At the same time,...
