| titleOfInvention | System for testing the communication capability of a network |
| abstract | A network 10 testing system comprises at least two link lines 12, 14 with a plurality of branches 20-1,..,20-n and circuitry which can block or transmit signals whereby all the branches, except that to be tested, can be arranged to block signals from the links 12, 14 such that the communication status (open circuit, short circuit) of the selected branch can be evaluated. The links 12, 14 and branches 20-1,.., 20-n may be formed from multiple electrical and / or optical lines which can carry energy and communication signals between different parts of the network. Each branch may include isolation circuitry to block or transmit signals. The isolation circuitry may be solid state or mechanical switches or a multiplexer unit connected between one of the links and the adjacent ends of the branches. The communication status of each branch 20-1,.., 20-n may be tested sequentially as instructed by a central controller unit 24 to detect and locate an open circuit fault within a branch. The test system may be used for alarm or emergency system networks involving a plurality of programmed processors and sensors for detecting intruders, fire, gas, position, etc. |
