If he selects only the phone numbers of A, then in Fig. 1 the subscribers A, B and C are one whose address is in the same line as the private branch exchange via two-wire lines to the address of C (line II), but in the column for the Inputs from associated subscriber circuits called subscribers are registered. Since the A is connected to TSA, TSB and TSC . From the just with whom B is speaking, C gets the occupancy of these subscriber circuits TSA, TSB and characters. Thereupon he can - if he is authorized to connect TSC lead four-wire connections to the facility - to dial a certain digit, press the amplitude samples from the speech frequency or a special activation key. Dagings of the subscribers according to the regulations of the will take out the address of subscriber B in the sampling theorems or the amplitude samples generated in such a column for the calling subscriber of a further type back to speech-free line, z.

These facilities are the addresses in front of all three subscribers are in the drawing as the amplitude ^{sample transmitter 35 of} the column for the calling subscriber. This is not necessary APS or amplitude sample receiver APE , since all participants sign with the fictitious participant. The outputs of the amplitude samples stations are to be mer »Anschaltesatz" connected, and recipients of Aufschaltetaste SS are connected to a voice bus Concurrent with the press is connected, through which the voice traffic by de subscriber C is in all three lines of participants is handled. The control of the ⁴ ° (lines 1,11, III) in a certain column of an amplitude sample transmitter and receiver takes place switching information Au and in another column by a circulating memory US, in which each row is stored in the address KN of the connection set The addresses of the calling and the calling party, as well as the traffic types, The Lugik circuit LS asks the individual memory callers and lines up one after the other and then always gives other information that can be entered. * ^{5 from} a clock pulse when it has found a line with the In-In the same way as the subscriber circuits formations Au and KN .

Simultaneously with the gik circuit LS, to which various command lines are connected to the ⁵ ° amplitude sample receiver APE-A , and the amplitude sample transmitter APS-I is actuated from mixing amplifiers, and at the same time the MVA, MV S, MV 6.

With the logic circuit LS , the mixer 55 subscriber A are first linked by the amplifier MVA, MVS, MV6. The amplitude theorems are chopped up into individual amplitude samples on the single-plitude sample transmitter APS-I according to the sampling path of the mixer amplifier MV 4, the test receiver / 4P £ -4 and APE-S are then placed on the Amrend input via the voice busbar SS Mixing amplifier MVS amplitude sample receiver APE-A , which combines the amplitude sample receivers APE-S and APE-6 6o individual amplitude samples again to the original signal and the input of the mixer MV ti and then the amplitude sample receiver APE-6 and APE-A to the mixer MVA given, given.
