Problems solved by technology

At this time, the usual practice in the prior art is to directly lead several groups of AU buses to the entrance of the time-division cross-connect matrix for time-division cross-connection. The disadvantage of this is that it will occupy a lot of time-division cross-connect resources, resulting in waste of resources.

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Fig. 1 is a schematic diagram of the core idea of ​​the method of the present invention. As shown in Figure 1, in the case of a certain time-division cross-connection matrix, several groups of effective signals to be synthesized into AUs whose effective services add up to not more than one AU are combined according to certain rules and synthesized into one AU; then The synthesized AUs are then sent to the time-division cross-connect matrix for cross-connect processing.

[0023] Fig. 2 is a flowchart of the method proposed by the present invention. As shown in Figure 2, the method that the present invention proposes to improve the time-division cross-connect matrix utilization rate comprises the following steps: Step 1, all signals preparing to enter the time-division cross-connect matrix are mapped in the SDH frame structure according ...

Abstract

The method includes following steps: (1) according to unitive AU pointer position signal, all signals ready to enter into the cross-interaction matrix are mapped to structure of SDH frame; (2) generating indicator signal of valid column corresponding to valid TU signal in AU signal of each route; (3) if sum of valid signals in several routes is insufficient to a AU signal, the a integrated AU is synthesized; indicator signals of valid column in several routes being as 'valid' signal are selected to output to signal; otherwise, fixed electrical level is filled up to the column of the output signal; (4) after integrated AU signal is filled to overhead of common VC4 channel and AU4 pointer, time slot cross module is introduced to carry out time slot cross processing. The invention raises utilization ratio of cross-interaction matrix of time division so as to rise cross capability of time division of system under certain cross capability of cross chip of time division.

Description

technical field [0001] The invention relates to an optical synchronous digital transmission system in the communication field, in particular to the design of a time-division crossover system in optical synchronous digital transmission equipment. Background technique [0002] In the design of the optical synchronous transmission system, the size of the cross-modulation capability of the signal is an important function index to measure the equipment. The design of the cross section in the system mainly includes the design of the space division matrix and the design of the time division matrix. The space division cross matrix refers to the AU (AU is the high-order pointer management unit in the SDH frame structure, which is the The information structure that provides the adaptation function with the multiplex section layer; it is composed of high-order VC and AU PTR) signal-level crossover, and the time-division crossover matrix refers to TU (TU is a low-order pointer managemen...
