the system of automatic telephone numbers matching central crossbar with 32 levels of selection

摘要

the invention relates to a coupling system with adaptive power plant automatic telephone ruralecrossber 32 levels of selection for maximizing the number of subscribers that can be installed properly itsfor the plant.this is done by placing, on the one hand, an adapter coupled subscriber, subscriber recognition for correct metering and ghost,electrical circuits for respectively in register subscriber recognition chemator ghostfor sending a pulse of 50 hz for the subscriber and for recognition chemator adapter ghost ghost called subscriber it 8.electrical circuits and central command marker transducer, electrical circuits in the transducer 8 subscriber recognition ghost called it,electrical circuit control line marker for testing subscriber's busy status line connect physical phantom,electrical circuits in junctorul local reversal of the line in the case of the subscriber local line reversal, if coupled to the subscriber call ghostcircuits with central command to local junctorul marker for reversing the line,in the case the call to the subscriber circuit in coupled phantom junction input reception pulse adjuster for 50 hz line reversal, if coupled to a subscriber call.
