A transmission device performing prescribed processing on signals of a plurality of channels and transmitting the signals of the plurality of channels. The device includes a first storage unit for storing, in different memory cells for each channel, first control data in which one or more types of control data elements for each channel are configured as at least one word data; a first data structure conversion unit for selecting control data elements of the same type from the first control data of the plurality of channels stored in the first storage unit, and converting the structure of the first control data such that the control data elements of the same type are configured as one word data; and a data generation unit for processing, in word units, the first control data after conversion by the first data structure conversion unit, and generating second control data necessary for the prescribed processing.

Transmission device for processing and transmitting signals of a plurality of channels

A fixed length data processing apparatus has a registration holding unit holding registration information necessary to identify fixed length data that is an object of a processing commonly to transmission routes, and a data processing unit identifying whether received fixed length data is fixed length data that is an object of the processing or not on the basis of at least the registration information in the registration information holding unit to perform a data processing for fault management in the asynchronous communication on the basis of the fixed length data when identifying that the fixed length data is fixed length data that is an object of a processing correspondingly to the transmission route, thereby holding a large volume of information efficiently for identifying fixed length data to process fixed length data with a simple structure.

Fixed length data processing apparatus

A fixed length data processing apparatus has a data processing unit receiving at least fixed length data to perform a desired data processing on the fixed length data, and an operation state monitoring process unit performing a monitoring process to monitor an operation state of an asynchronous communication on the basis of the fixed length data received by said data processing unit, thereby detecting loss or misinsertion of fixed length data such as an ATM cell or the like and monitoring a flow state in a transmission system having a high transmission rate.
