The invention discloses a tester and a test method for transmission digital distribution frames. The tester is provided with a test board. The test board is matched with the size of a transmission digital distribution frame connected with an interface board of transmission equipment E1, at least one row of test connectors is arranged on the test board, and the intervals between the test connectorsand the locations of the test connectors are in one-to-one correspondence to normal-state switching connectors on the tested transmission digital distribution frame; test loops which are formed by abattery, switches and light emitting diodes are further arranged on the test board. The tester and the test method have the advantages that the test board can be plugged, the interface board of the transmission equipment E1 and transmission equipment can be in a connection state and a disconnection state, and whether distribution frame connectors and connected wires are normal or not can be quickly judged from the two states; all coaxial cable connectors on the digital distribution frames can be tested by the aid of the tester and the test method in a batch manner, accordingly, the test time can be shorted, the tedious degrees of test procedures can be lowered, judgment procedures can be simplified, and the error rates of tests can be lowered.
Description
technical field [0001] The invention relates to the field of digital transmission, in particular to a transmission digital distribution frame tester and a test method. Background technique [0002] Digital distribution frame, also known as high-frequency distribution frame, can connect the digital code stream of digital communication equipment as a whole, bringing great flexibility and convenience for wiring, line adjustment, transfer, and capacity expansion. Since the inner and outer conductors of the distribution frame connector are connected to the external lines through the connected wires, but the connection between the coaxial cable connector and the wires of the small-sized distribution frame is very prone to short circuits between the inner and outer conductors of the connector or the wires and wires. In the case of a short circuit between conductors, it is crucial to test the digital distribution frame after the construction is completed. [0003] In the prior art,...
