摘要： There is provided a communication control method for a network including duplexed ring transmission lines and a plurality of communication controlling devices each accommodating a plurality of terminals and adapted to transmit data sent from any of the terminals and receive data over the ring transmission lines, the communication control method comprising the steps of: causing one communication controlling device to transmit monitoring cells simultaneously over the duplexed transmission lines, the monitoring cells each including a pass indication area for retaining a source address and identification information for identifying a passed communication controlling device; and causing another communication controlling device which receives the monitoring cells respectively from the duplexed transmission lines to relay and circulate the monitoring cells respectively over the duplexed transmission lines after writing in the pass indication area of each of the received monitoring cells data indicative of passage of said each monitoring cell. The communication control method improves the efficiency of the fault monitoring and fault reporting on the transmission lines of the ring LAN.

摘要： The present invention relates to a frame communication system composed of a code converter and a frame generator/decomposer. In order to improve a line efficiency without encapsulating transmitting data, a code converter in a frame transmitting device converts at least different specific codes X and Y within the transmitting data respectively into codes (Y, A) and (Y, B) composed of the code Y and at least specific codes A and B different from each other, and a frame generator prepares a frame of the transmitting data with the code X as a frame boundary. A frame decomposer in a frame receiving device recognizes a specific code X as a frame boundary to decompose receiving data, and a code converter converts codes (Y, A) and (Y, B) within the receiving data composed of a specific code Y, and specific codes A and B into codes X and Y.
