Description

In order to speed up the connection, it has already been provided in the known devices, during the digit suppression from the direction selector, a backward search to be transmitted back to the memory, which _acts here when sending the digits to be suppressed a shortening of the intermediate dialing times. However, is the suppression itself going to be found in the direction voters and not in the upstream scouts? made because otherwise an In- ι. information on the number of digits to be suppressed from the direction selector to the connection * - W-. Upstream storage would be recovered, which is not provided because, despite an additional technical ₃ Aufwindet required for this, no time savings can be achieved

Due to its drop-out delay, it corresponds to a bundle of cables that only speaks a certain number of digits to be suppressed at the beginning of a series of dialing pulses. times on and remains on for its entire duration - the direction selector now finds 5 in which it was initially spoken. Each time it is addressed, there is no free line to the previously mentioned counter Z. Each time it receives and controls another line-intercepted dialing pulse series, a pulse is sent off. The fact that the bundle changes, as a rule, each of these dialing pulse series only consists of a single one which, when checking for a free line, is not perceived by the counting relay V or by the other line bundle to be suppressed digits m counters.

When continuing to press the As soon as the digits to be suppressed of the dialing code number routing bundle, the digit sub-information in the direction selector RW is no longer available. and have been suppressed here, a relay Y is actuated by the according to the original direction counter Z, the contacts 1 y marking set above counter Z is 15 and 2 y carries.

Furthermore, the contact 2 y adjusts the fact that the counter setting of the number of the 20 output to the relay F in the register KRG is switched off when checking for a free line of the respective signal. The relay F drops out. As a result of the line bundle of digits to be suppressed, the contact 1 / is now separated again, contradicts itself. If the direction selector has now reached a free one from the storage circuit b from the line, then its test relay responds, the memory 5 removed further digits of the dial, among other things, closes its contact Ip.

In this case, even if the intermediate dialing times are shortened, the assignment of the wiring harness will be changed by evaluating the saved digits. Each dial setting that precedes this directional dialer is converted to a "one". The digits on the relevant output group of the relay Y arrive via the circuit t in the register KRG via a direction selector RW located in the marking test circuit, not via the counting pulse generator ZlG on the wire d 'of the shown second winding .
