Abstract:
A system for testing the repeating installation, comprising:a repeating installation including a first transmitter-receiver, a second transmitter-receiver having a plurality of outputs, and a line controller connected between said first transmitter-receiver and said second transmitter-receiver;a first tester connected to said first transmitter-receivers for sending test data and a destination address;a second tester having an inputted connected to one of said plurality of outputs of said second transmitter-receivers and an output virtually connected to a virtual network including a plurality of virtual terminals, for receiving said test data, said virtual network and said virtual terminals being virtually present and being not physically present; andan input unit connected to said first tester for entering, as said destination address, a virtual address of said virtual network or virtual terminals;said line controller having a control table for making a correspondence between said virtual address and a path directing from said line controller to said second tester in response to said virtual address so that, when said test data and said virtual address are sent from said first tester to said line controller, said line controller establishes a connection between said first tester and said second tester through said repeating installation by referring to said control table to send said test data to said second tester, so that said second tester receives said test data without sending the test data to said virtual network or said virtual terminal, said second tester determines whether or not the received virtual address is directed to said second tester and determines whether or not the received test data is correct by checking the contents of the received test data to examine said repeating installation.
