PURPOSE:To realize an interface between systems by using jumpers to preset a number designated at a test board to a trunk of a supervisory test equipment corresponding to the number, reading the jumpers by the supervisory test equipment and storing the result of reading of the jumpers as station data corresponding to the allocated position of the trunk to the said supervisory test equipment. CONSTITUTION:The jumpers X0-Xj are provided to each trunk circuit and the trunk numbers l+1-l+m corresponding respectively to the test board are set by the jumpers. In case of l+i=100, for example, Xj-X1, X0=1100100 is obtained and terminals of bit location corresponding to ''0'' are jumpered. The supervisory test equipment 8 reads the trunk number of all trunks at the set test board once at the initial setting and stores in a memory 12 of the supervisory test equipment 8 corresponding to the trunk numbers 0-m-1 at the exchange side. When the trunk number l+i is designated in control information, the supervisory test equipment 8 scans sequentially the memory 12 and searches an address in which the l+i is stored. The exchange identifies the corresponding trunk from the trunk number in the control signal in this way. |
