Description

GERMAN

The main patent relates to a circuit arrangement for only partially expanded telecommunications, in particular Telephone systems with registers and markers, the former of which are several sets of storage relays for coded recording and forwarding of the incoming, the respective traffic direction and / or the call number of the desired Contain series of current impulses identifying the remote station. To save storage relays, the Main patent suggested that depending on the value of the first recorded, an expanded Subscriber group or a certain traffic direction characterizing digit each one of the relevant Relay assigned to the number and responsible for the corresponding control of the switched-on marker is switched on, the switching means that takes effect when this relay is switched on Recording of this series of current impulses used storage relay set as well as the remaining, the If a series of current impulses has been entered, it resets the register's switching means, and so on influences that the subsequent series of rushes is again carried out by the series already carried out by the first series of rushes set memory relay set can be included, while if one is selected, a non-expanded one First digit identifying participant group via contacts of the set storage relay of the first storage relay set, the triggering of the already set connection part and the register is effected.

In the arrangement according to the main patent, special counting-down means are provided which indicate the number measure the current impulses of each incoming series of current impulses and depending on the result of these Measurement affect the storage relays of the individual storage relay sets. The invention avoids this special counting means in that the first or the first of the call number of the desired Opposite station forming series of current impulses through both the counting and the encoding storage a set of storage elements enabling a series of current impulses and included in Dependence on the value of this series of current impulses only for storage and evaluation Memory switching means are transmitted and that the subsequent series of rushes of this after the Restoring the set of counting and storage elements that has become free again, as well as, if applicable further sets of similar counting and storage. elements individually recorded and evaluated will.

This results in the additional advantage that for the evaluation of the storage relay sets recorded first digits of a code number a circuit arrangement for telecommunication,

have been named as inventors

A sufficient number of contacts is available because the storage relays storing the first digits are not used for counting purposes, which in themselves already require a certain number of contacts on each counting and storage relay. Since the first digits of a code or a phone number determine the direction and consequently also have to be checked whether a calling subscriber is authorized in the desired traffic direction, it is necessary to evaluate the first or first digits of a phone number in multiple ways, which of course a multiple Kontaktauf wall requires digits that are only to be transferred to the markers already occupied by the preceding digits in order to determine the desired subscriber line in these. ■ ■ _:.

An embodiment of the invention is shown in the drawing. This is shown in FIG. 1 and 2 the switching of a register for recording and evaluating four-digit call numbers.

The basic structure of the telephone system for which this register is suitable is shown in FIGS. 1, 2 and 3 of the main patent has been shown and its basic features have also been described in this main patent, see above that a repeated representation of the connection system is waived in the context of this additional patent can be. . ;

Each impulse when dialing a subscriber's own partial number corresponds to the checksum of the forward paying group as well as when selecting, cross-connection of two energized relays with the exception of the impulse digits, exchange and message line digits in the own number .10 , there. when ten pulses are received, the marker is there, while when a relay is received, 4 Z and 7 Z are excited. In addition to this actual call number, which: a subscriber of another partial borrowed storage relay OZ to 7Z is assigned an auxiliary relay F taker group, the marker of this available, which is occupied when the fifth pulse of the subscriber group arrives. In addition, more and more groups of participants are to be addressed and for the duration of the individual participant groups: Large groups continue to run together with further impulses and the perception and who has been assigned to such a large group, in addition to the contacts of the already th markers, are through a Register only energized or not yet energized storage relays that are occupied when the desired connection leads to a switch-on and .stalting circuits of the following large group, -to which the calling part- to prepare the storage relay to be excited or who does not belong to.

' Just as in exactly the same way as the main patent, two 100 groups form a common storage relay set Oz to 7Z.

The above description of the effect is inferred.

This is transmitted via the line from to the four-digit number between the terminal register and brings the relay AB men IA and 3h dashed solder bridge over its winding II to respond. With which must be inserted. With a three-digit connection contact from III1, the further transmission of service numbers is therefore the relay UH already with this switch-off command in the internal connection set of the relay S for the first time, i.e. already during the io IVW, and after its triggering, the relay 7 input of the 100 digits drops , to suit over on the tab. As a result, the relay V is through contacts sI2 and illll. The counting of the short-circuit pulses thrown across the contact till I; and takes place in turn by the counting and storage since all holding circuits of normally open contacts relay set OZ to 7 Z, and at the end of the pulse train of the relay V are dependent; If the activation takes place, the contact s Uli falls through 15 of the register, so that from this point onwards a new assignment is available for the contacts / Il those of the Re which are still activated, lais the storage group OH to 7H for addressing the The register can also be switched off in accordance with the stored position of the dependency on the fact that various conditions OZ to 7 Z correspond.

These conditions exist as described above. in that the calling party is authorized.

The information stored in the register is passed on to the marker as soon as it is in the register. If there is no such authorization, the end of the election is recognized.

If it is a question of partial fertilization in the 10,000 system, a corresponding authorization is required from an acceptor of the own 1,000 group and is therefore necessary for the 40 calling subscriber, and for this calling and the called subscriber, for example, the relay BB is provided, which is only partially assigned to the first thousand, then as a result of the response, when a subscriber selecting a cross connection of the first recorded digit of the contact Ii 12 actuates the corresponding cross-des 100 relay IT.

If a group is not expanded, terminal 4 is assigned to When a message line is selected, which is connected to terminal 4 σ, and number 9 is assigned via the contacts. is, comes via the contacts 4 / iII2 and 0ÄI3 and the contact kr III, I2II2 and 72II2 and the winding III, the relay 15, the relay AT responds. Switching on the relay KR earth, 22II2, Gr 3, KQ winding I, 2ill, IiIl, UH winding I, H2, uzll, sf 11, sllll, vll, from 12, -. The relay KQ also excites with its contact grill KQ to respond. If such a participant is not authorized to cross-connect at the same time, the switch-off relay AT cannot respond because the circuit for this relay is separated by contacts 2ÄlH and 7MIl. The two-digit cross-connection codes are assigned the relay KR instead of the relay KQ. For example, if the first digit of the two-digit cross-connection code is 6, the KR relay responds via: Earth, 2zll2, Gr 4, KR winding I. 4 ^ 12 ,. 2ill, IiIl, UH winding I, H2, uzll, sfll, sllll, vll, from 12, -. The relay KR goes into self-holding with the help of the contact Ar II2, and the digit 6 stored in the relays OZ to 7 Z coded is now stored in the known manner in the relays OH to 7H in coded form and thus the relay set OZ to 7 Z for The second digit of the relevant code can be included again. When the second digit is recorded, the relays OZ to 7Z are counted again and then saved. The end of the election is recognized after the second digit has been recorded, and the relays KZ and WE respond in series via the contacts we 12 and kr Il. When dialing a cross-connection code, a message line code and an exchange code, the marker of the group of 200 to which the calling subscriber is assigned is used. If, as a result, the calling subscriber belongs to the first group of 200, the output terminal ma is routed to the output terminal m 1 in the relevant register, as is the output terminal mq. and ml. If a subscriber has dialed the reporting line code, the marker of the first group of 200 is assigned, if the calling subscriber belongs to this group, via contacts 7 / ill 1 and 2hII2, since output ml with output m 1, that leads to the marker in question is wired. When a cross-connection code is selected, the relay KZ responds, as described above, and as a result, there is a connection from terminal mq to terminal m 1 via contacts bb III I and kzll for authorized extensions. Output m is also assigned when the line code is selected 1, which leads to the marker in question, now via the contacts ba III1 and ka 12 as well as the ma terminal Two-digit code numbers via also coded selected contacts of the relays OiT to 7H and Oz to 7Z to which is done in this case via the winding I and the contacts, 4 212 and 0 2III2.
