Abstract

PURPOSE:To take out bidirectional data flowing between a terminal equipment and a communication equipment to a communication monitoring device by providing a switching function of the fetch port of the bidirectional data and a monitoring function for the data on the line monitoring distributor a monitoring function for the data. CONSTITUTION:By using the line monitoring distributor, the more inexpensive and easier monitoring of a communication line can be realized with the help of a commercially available personal computer, etc. As the result, influences caused by communication failure can be minimized. A distributor 1 for line monitoring, called T-type branch, switches the communication line of the fetch port at the moment of starting the flow of bidirectional data An or Bn, and sends the always flowing data to a communication monitoring device 2.
