MULTIRATE COMMUNICATION DEVICE AND LINE CONFIGURATION CONTROL METHOD THEREFOR

摘要

It is provided on an interface board provided on the multirate communication apparatus accommodating the SONET/SDH lines and controls the configuration (type and number of lines) of lines processed at respective signal processors provided on the interface board in response to the bit rate (line speed) of a transmission module mounted on a reference port among ports mounted on the transmission module. There are provided a plurality of groups processing the signal of a second line capacity obtained by dividing a first line capacity processed by the interface board; a port connecting lines that transmit the signals processed by the respective groups; a line identifying unit identifying a line type of a transmission module mounted on the port by receiving and transmitting the signals; a line-configuration controller controlling a configuration of lines accommodated in the respective groups on the basis of an identification result from the line identifying unit; and a signal processor processing the signals in accordance with the line type of the transmission module mounted on the port on the basis of a control by the line-configuration controller.
