titleOfInvention | Special automatic trunk testing arrangement |
abstract | Abstract of the Disclosure An automatic trunk test arrangement is disclosed which performs transmission path monitoring on idle trunks in the normal manner and which routinely scans th? supervisory states of trunks primarily for call charging purposes. When predetermined supervisory states are detected at any trunk, the routine testing of idle trunks is interrupted. The identity of the idle trunk under test is stored, and the test multiple is seized to connect the busy trunk exhibiting the predetermined supervisory states to the test multiple so that call signalling appearing on its transmission path conductors may be monitored. The connection of the transmission path monitoring apparatus is thus restricted to only those busy trunks exhibiting a predetermined supervisory state. |
