摘要： A pointer processing apparatus in an SDH transmission system used to serially conducting a pointer process on inputted multiplex data has an address generating unit for allocating an address to each channel of the multiplex data, a RAM for holding an information group obtained by a pointer extracting process and a pointer process, and RAM controlling unit for controlling a sequence of an operation to write-in/read-out the RAM to serially conduct the pointer process on the received multiplex data, thereby largely decreasing the circuit scale, the power consumption, the number of distributions and the like. A POH terminating operation process is conducted in a POH terminating operation process unit, and an obtained result of the POH terminating operation is stored in a storage area for a corresponding channel of a storage unit, whereby the POH terminating operation process can be conducted without separating a multiplex signal into channels. By conducting the POH terminating operation process on the multiplex signal without separating the multiplex signal into channels, a scale and a power consumption of an apparatus can be largely decreased.
