This invention discloses a business access protector used in SDH / SONET transmission equipment, which contains interface unit, process unit and control unit wherein the interface unit is connected with process unit through control unit consisting of exchange controller for sending relative route control signal according business pass way state of interface unit and process unit, route controller for scheduling the interface unit received business signal to relative process unit to be processed. Said invention is benefit to intelligent control the business protection.

Description

Technical field [0001] The invention relates to a service protection device in the field of telecommunication services, in particular to a service access protection device that can be used for synchronous digital system / synchronous optical network (SDH / SONET) transmission equipment. Background technique [0002] At present, SDH / SONET optical transmission network has been widely used in the communication field. SDH / SONET transmission equipment generally accesses service signals of different rates, and then encapsulates or processes the service signals, and then changes the transmission path through service crossover, so that the service signals can finally be delivered to their destinations to realize data transmission . Because the service signal rate connected to SDH / SONET transmission equipment is relatively high, generally from 1.5M to 155M, 10M to 100M, and even GE (Gigabit Ethernet) services. The types of services include audio, image, data, etc. These service signals are ve...
