た。tb+ Prior Art and Problems FIG. 1 is a diagram showing an example of this kind of conventional line testing equipment. As shown in FIG. 1, a line testing device 4 is attached to a telegraph exchange 2 that accommodates a plurality of telegraph lines 1. Telegraph line III to be tested is connected to line testing equipment 4 via test jack rack 3'. The line test device 4 is
a control unit 6 equipped with a line test mechanism 61 that performs various tests on the telecommunication line 1 to be tested;
1, an auxiliary storage section 8 for storing the contents of the storage section 7, a bus 9 for connecting the above-mentioned sections, a test teleprinter 5, Changeover switches 108 and 11 connect the test teleprinter 5 to either the control unit 6 or the test target telegraph line 1, and the signal levels of the telegraph line 1 and the test teleprinter 5 are set to the logic level of the control unit 6. The line test mechanism 61 of the control unit 6 generates a series of signals conforming to one time condition in order to test the telegraph line 1@11. The time conditions are not necessarily constant depending on the type of subscriber telegraph line IR1, so the line test equipment 4
- There may be cases where changes need to be made after installation. In order to change the time conditions, conventionally, a test device 14 is provided, and data storage locations, update data, control signals, etc. are input to the control unit 6 via the bus 9, and the line test mechanism 61 or It is necessary to update the data set in the storage section 7, and there is a risk that the economical efficiency of the line testing device 4 may be impaired.
