Abstract
The invention relates to a method and device for realizing normalization of TDM (Time Division Multiplexing) and grouping mixed services. The method comprises the following steps of: dividing service signals of the mixed services into a TDM service signal and a grouping service signal; respectively treating the TDM service signal and the grouping service signal according to different treating ways; selecting an output channel for directly outputting the TDM service signal or the grouping service signal after being treated to a packet-cutting grouping module; and sending the TDM service signal or the grouping service signal after being treated by the packet-cutting grouping module to a rear panel crossing or downstream service unit in a cell or packet mode, so as to further treat. According to the method provided by the invention, without using any signal spending, the treatment for the TDM and grouping mixed services is realized in a set of system or sub-card, so that a client does not need to use two or more sets of systems or sub-cards for realizing the mixed networking of the TDM service and grouping service, the networking cost is saved, and the forms of equipment and single disk are diversified and are more flexible.
Description
Technical field
The present invention relates to technical field of optical network communication, is method and device that a kind of TDM of realization and the normalization of grouping mixed service are handled specifically.Mixed service promptly refers to TDM business and Packet Service and deposits.
Background technology
No matter be the long distance transmission from business, the professional rapid growth angle of still following IP class is considered, adopts TDM (Time Division Multiplexing, time division multiplexing) business+Packet Service to unite networking model and all seems very necessary.Consider many advantages of associating networking model, except do not have TDM professional or in a short time the TDM business can't cover area to key core point, all suggestion adopts the associating network's mode to carry out the construction of metropolitan area local network.TDM business+Packet Service associating networking model relies on its powerful IP operation to insert, converge and the flexible dispatching ability; To help promoting MAN transmission network towards flattening network evolution unified, that merge, be the optimal selection that transmission network of future generation is set up in each operator.
In the intersection equipment of prior art, generally adopt the mode of this separation of TDM system+grouping system to carry out TDM business+Packet Service associating networking.Owing to use two cover systems, cause two cover systems when butt joint, to need extra control, and the repeated use of two some function of cover system cause networking cost too high.
Summary of the invention
To the defective that exists in the prior art; The method and the device that the object of the present invention is to provide a kind of TDM of realization and the normalization of grouping mixed service to handle can be under the situation that does not take any signal overhead, in a cover system or subcard, realize the processing of TDM and grouping mixed service; Make the client when realizing TDM business and Packet Service mixed networking, need not use two cover or many cover systems or subcards; Save networking cost, made the variation of equipment and single-deck form, had more flexibility.
