Title: Telephone PBX with central receivers and converters - has temporary speech circuit provided through translation contacts until final speech connection is established
Inventor: STAEDTER WILHELM
IPC: H04Q3/42
Filed: 1976-08-12
Abstract: Receivers and converters are connected or receiving and transmitting sides through corresponding switching points of a connecting unit to the receiving or sending side of line translation. Received dialling pulses or key dialling signals are intermediately stored and/or converted, and returned to the line translation in the form of, e.g. pulse dialling signals or multiple frequency key dialling signals for their retransmission. Transformer winding (L/I, II; L/III, IV) inductively coupled with each other are connected in the first path receiving dialling signals and in the sending path of the central receiver and converter unit (R). They form through translation contacts (1u-4u) a path permitting also speech transmission from callin gto called side until final speech connection is established. Transformer windings (II, IV) in the sending side are made inoperative only during signal reception and transmission.
