Test circuit arrangement for computer-controlled communications switching systems |
摘要 |
A test circuit arrangement for testing computer-controlled communications switching systems each having a central network and a central processor unit, as well as subscriber sets and/or line sets connectable to the network for analog and/or digital information transmission. These subscriber sets and/or line sets are in communication with the central processor unit under the control of a group processor unit adapted to the plurality of subscriber sets and/or line sets. A communications switching system to be tested is connected to a line trunk group configuration composed of subscriber and line sets, manual switching position and digital stations and is function-tested with a personal computer unit connectable via the group processor.
