DE1015471B - Arrangement for the transmission of telex charges - Google Patents

Description

The invention relates to an arrangement for transmitting telex charges to the calling party Participants after the communication link is terminated.

There are already known arrangements for the transmission of charges, in which the office has a corrector that converts the charges into pulse combinations that can be generated using the Name giver text can be assigned to a certain telegraph meter in the office. With these Arrangements are not intended to ascribe the charge pulses directly to the calling party. One solution to the problem is given by a different arrangement in which the time zone counter determined fee after the end of the telex connection to the calling subscriber in the form of Telegraph characters sent and there put down by the normal teleprinter will. The transmission of the charge impulses on the line to the calling subscriber takes place after this Final signaling via a special contact, who for the time of the transfer of charges via relay and rotary selector is connected to the FR wire of the exchange line to the subscriber. With this arrangement are on the one hand an additional relay and further switching means to avoid mutilated characters necessary to reassign the selection, on the other hand is because of the dependency of the entire Switching of the unpredictable duration of the keystroke on the part of the subscriber giving the final signal a complex circuit is necessary.

The invention solves the problem with much simpler means by proposing that one of a scanning device, the corrector controlled contact in the fr-wire of the trunk line so before The transmission link is looped in so that it can handle regular write traffic in one position and in the other Position the further assignment of the connection line and the transmission of the write charge characters Control of the transmission relay effected.

It is known from telephony to loop a changeover contact into the fr wire in such a way that that the exchange of messages about his working situation and the recording of charges about his idle situation can be done. For the present task, however, this arrangement is not applicable because the Telephone traffic the two wires form a line loop while they are in teleprinter operation perform separate tasks as a send and receive path.

The arrangement according to the invention is explained in more detail using an exemplary embodiment. For example becomes the official billing meter, which is provided for each participant. a facility to

orderly, for example in the form of counting drums, which instead of digits 0 to 9 have the corresponding symbols of the perforated

wear ao bar codes. Induced by the final sign, these drums are scanned and the resulting impulses are now teletype impulses corresponding, using the known switching means in the office assigned to the subscriber. Appropriately, this notice is marked as charges, in addition to the movable ones Drums still a fixed text, also in punched tape codes, before or after the fee numbers is transmitted and this, for example, by the Marks the addition "Ge" as fee units. If necessary, the revaluation can be carried out as follows: that instead of the number of charge units incurred, the corresponding amount is transmitted in DM will. The described transfer of the fee units is triggered by the subscriber closing code, whereby the line to the subscriber remains busy at the same time due to switching measures or is occupied again immediately until the charge units have been assigned. At the end of this process the additional device automatically releases the line and causes its own reset to the initial position.

A circuit that allows the operations described to be carried out is shown in the sketch as an example reproduced. For the current flow of the other circles, the known circuits z. B. according to Fig. 4, p. 18 of the special print (1953) "Die Telegraphenwähltechnik" the "instruction sheets of the Deutsche Bundespost" are used as a basis.

Fig. 1 a shows the additional writing fee device SG1, which is connected to the usual fee meter Z in the office. Instead of numbers, the counting drums T carry corresponding characters according to the code of the punched tape transmitter. You will be affected by the electromagnetic

table switching mechanism M is moved in the rhythm of the counting current surges coming from the time zone counter ZZZ. The scanning device AE evaluates the set characters in such a way that the characters corresponding current surges _{excite the ReIaIS 1} S ¹ I as soon as the transmission of the writing fees is released by the contact A 2.

Fig. 1 b shows the circuit of the preselector for the receiving direction E. The changeover contact s is new compared to the known circuit. It is controlled the Sch-reibgebührengerätes SG from the relay Sl. During the write state, s lies in the position shown in broken lines, so that the write pulses can act on the relay B. B controls with the contact b (Fig. 1 c) in a known manner the writing magnet of the subscriber device FS. In the excellent position controls. «■ the relay B for the transmission of the charge signs after the end of the write transmission: As is well known, the relay R (Fig. Ic) drops out due to the final signal; an auxiliary relay H (Fig. 2) comes into operation via rZ, provided that a contact controlled by the counting drums is closed depending on the charges received. Relay H maintains itself via the contact Al and switches on the scanning of the charge drums in the additional device SG with h 2. The relay S is energized by a first character, the contact s of which brings the relay B into the separating position, whereby the subscriber line is immediately occupied again in a known manner. The contact s now oscillates in the rhythm of the characters on the counts drums and transfers the characters on B, b to the subscriber. At the end of this transfer, s remains in the dotted rest position; this brings B into the character stream position and disconnects the connection (selection runs home, the subscriber becomes free).

The transmission path is shown in Fig. 1 d. During the transmission of the charge writing pulses, only the selection was started. The transmission of the charge symbols could therefore have disruptive repercussions on the dialing system that is now open to the group dialer. A contact A3, which interrupts the transmission line, avoids this because the relay H is switched on during the transmission of the write charge pulses.

As an extension of the idea according to the invention, instead of permanently assigned additional writing fee devices SG, a search selection can be made to assign one of several such devices to a writing subscriber. The existing relay R with the additional contacts r 4, r 5 can be used for this purpose. Fig. 3 shows how these two contacts act in a loop circuit on the rotary selector magnets Dl, D 2 , in order to bring the associated selector arms to their own stimulus circuit, omitting all switching means that are assumed to be known. A free writing fee additional device SG 2 switches itself on via the contact r5, the contacts c, p of relays in test circuits (not shown) of the search dial becoming effective. The counting pulses from the time zone counter reach the additional writing fee device SG2 and act at the given time on the assigned relay S2, which takes on the other functions in the manner described above for S1.
