Solicitation arrangement for call points with a main line to the office and two Pleben connections in automatic telephone systems

\ amuoL · h1 of a helais set attached to the / (H & uptstelle), while the call station sets der-Jiaup * ---- ua4 are designed as single subscriber sets with additional earthing sets. To establish an exchange connection, the grounding button is pressed; bringing about a hay bsw. Internal connection, however, is made by dialing the number "1 ⁿ or" 2 ". The establishment of an inquiry connection is again initiated by pressing the DraungEteste, whereupon the extension is dialed The invention is based on the object of restricting the operating mode to only a few operations that are clearly recognizable even to the untrained subscriber. Internal connections are only established by pressing the earthing button on the intercom. This operational separation of the two switching means, TTurnmernsehe lter xuia "earthing button, results in a significant simplification of traffic management, especially in the event of a query.

2 _# ) Inquiry from main unit N1 to extension F2 during the official conversation :

The main unit N1 presses the earth button TTT1, whereby the Winding D1 (ll) dea differential relay is closed and DI responds via the first winding D1 (I)

Both extensions are connected in parallel to the normally closed contacts f1III, IV and f2lll, IV ", so that the Spreofaweg is possible without any further problems.

If the extension N2 does not hang up the handset despite a request from the main terminal N1, the latter is deprived of the opportunity to return to the still existing exchange connection. If the point H, waiting in vain, hangs up the receiver En, the relay Al and a little later ... ^ eIf is— X is de-energized, the Beiais Z is briefly excited, whereby the Amtorel is excited as F2 of the extension Ή2 via:

By lifting the handset at the extension K2 .ground, as explained, A2 and Y are energized. If the dial at number "1" is pulled up, the -th ^ r2 price drops and energizes relay Z temporarily.

The brief drop in R «Xaie A2 causes the number prefix
