Description

Arrangement for time zone counting in telephone systems In telephone systems with voter operation it is known to automatically record the call charges after the respective connection has been removed and according to the duration of the conversation to use so-called time zone counters. They consist of switching devices, soft through the area code of the desired area dialed by the calling station Participant can be set, and from timer devices, which the duration of the conversation. The one corresponding to the setting of these zone and time switches The fee is charged either when the connection is terminated or at certain time intervals during the call by sending power surges to the meter of the calling party Participant charged. These time zone counters are one of the main or Node offices of the individual local networks arranged.

Should such time zone counters also be used for long-distance traffic Country and for international traffic (world traffic) are provided, so result face significant difficulties. While for local transport the distance in general can be determined from three outside line codes selected by the calling station, with which iooo different distances can be recorded, are for long-distance traffic up to five code numbers and even more required in world traffic. One would based on the previously known arrangements for the time zone count the .in, the local networks available. Facilities for, world and long-distance transport expand, this would require a great deal of effort, which is economical is completely unsustainable. Even one only the percentage of the wide and World traffic expansion of the time zone counter adapted to the total number of all connections in the local area networks, apart from one necessary modification, the known Facilities still mean too much effort: object of the invention is to become an economically viable arrangement for long-distance and world traffic create what is achieved by the fact that similar devices for time zone counting for local traffic to the main or node offices, for long-distance traffic in every country the end remote offices and, for world traffic, the distribution or transit offices assigned.

According to further features of the invention, the time zone counters in the higher-level offices only after the code numbers for the person concerned have been selected Type of traffic set, while the facilities assigned to the main or node offices for time zone counting when selecting the code numbers for the. Long-distance traffic out of service be set.

The invention is based on the knowledge that the percentage of long-distance and global traffic is very low in relation to the total number of all connections. On the other hand, the trunk lines that can be reached are in the end, distribution and transit offices combined in large bundles. The greatest effort is undoubtedly made by the facilities assigned to the main or nodal offices of the individual network groups Each increase or expansion of these facilities affects therefore in the whole particularly large.

When arranging the invention is for the introduction of a automatic time-zone counting for long-distance and world traffic by arrangement the facilities required for this in the for these types of transport only to a great extent a small number of existing offices requires relatively little additional effort, which is economically justifiable. Furthermore, there are no special ones for this trained or newly to be developed switching devices and circuits required, because the same, well-known and in practice proven time zone counters for everyone Types of connections are used. This is from the following knowledge possible: In local transport, the distances are increased in small steps from io and 25km, in long-distance traffic in steps of 100 km each and in world traffic in some cases based on larger levels. The known zone switches allow recording of three indicators, d. H. So the determination of iooo different distances, which are known as zoning points. Also for long-distance traffic within one Landes, this number is absolutely sufficient there. probably in no state with more than iooo end remote offices can be expected. The same also applies to world traffic.

Every known type of time zone counter is used for the invention the representation of the individual switching devices and: Circuits. In long-distance traffic, the fee calculation is based on the distance of each Network group centers and in world traffic the distance of the individual distribution or transit offices in the various countries. The zoning, d. H. the wiring of the connection contacts of the zone switches with those of the tapping or counting switch, takes place for all types of traffic in the known time-zone counters usual way.

The connection can be established in the arrangement according to the invention .in the manner shown in the drawing. Wishes. a calling subscriber T .des sub-office UA establishes a connection in his own network group, he arrives via the preselection VW to the group selector GWi of his account office KA, where a time zone counter ZN is switched on. He selects the digit zero and thereby sets the group selector GW i to a free connection line to the end remote exchange EF located in the center of the network group. Subsequent transmission of the actual code, ie of two series of current impulses characterizing the desired local network, the zone switches of ZN are set at the same time with the selectors GW 2 etc. to establish the connection. The setting of the latter indicates the distance between the local networks and identifies them on the counter switch or on the other devices of the time zone counter ZN which control the transmission of the counter current surges to the counter of the calling station.

If, on the other hand, a subscriber wants to establish a connection to a subscriber in another network group in the area of his own end-line network (local traffic connection), he first selects two zeros. After reaching the End'fernamte§ EF of his own network group (first zero) he is further connected to the group selector GW 3 in the remote distribution office VF by setting the group selector GW2 when selecting the second zero via the reversing selector UW t. After the second zero has been recorded, the time zone counter ZN in the main or node office KA is switched to three key figures in a known manner. The recording and evaluation of the code numbers is carried out in the same way as described above.

To get to a transit or world remote office, the calling station must select three or four zeros. It reaches with two zeros via the group selector GW 2 and the reversing selector UW r of your end remote office EF. The group selector GW 3 in the distribution remote office hF. This selector is set by selecting the third zero and causes the selector UW i to be reversed to a free one via the reversing selector UW 2 in the distribution area VF to a group selector GW q. trunk line leading in transit remote exchange DF. A time zone counter ZW for world traffic is connected to this at the same time in the end remote office EF, which is controlled by the two codes of the wide-area telephony code selected below in the same way as described above.

The calling subscriber dials a vierte.Null, then the group selector GW 4 to a free, - to the group selector GW set 5 leading in global toll office WF transmission. After recording the fourth zero, the devices of the time zone counter ZW in the end remote office EF are switched over to the evaluation of three codes.

For world traffic, the participant chooses five or six zeros. Each of these different choices can identify a different group of world traffic links. If the group selector GW 5 is set by the fifth zero, the selector UW 2 in the distribution remote office VF is reversed to a group selector GW 6 of a special group Gr via the reversing selector UW 3 in the transit remote office DF. 2 long-distance line leading in the world remote office WF with simultaneous connection of a time zone counter Z1 i) in the remote distribution office hF. Should the group selector GW 6 be set by a further (sixth) zero, then the selector UW 3 is redirected to a long-distance line leading to the group selector GW 7 in the world remote office WF. Other groups Gr.3 of world traffic connections can be reached via this selector, such as via the group selector GW 6. A time zone counter Z, 12 is connected to the long-distance line occupied by the UW 3 selector. In the transit remote office DF, a time zone counter Z, 12 is switched on while the counter Z.1 i for the remote distribution office hF: world traffic connections are switched off at the same time. however, generally not produced by the participant offices themselves, but through the mediation of an officer. The one for it. required remote places can be arranged irr the end or distribution remote offices. The drawing shows on its lower part an embodiment in which the remote places FP i, which are also used to handle global traffic; are located in the end remote office EF.

Each remote link consists of a reversing selector UW4 and a group selector I. GW, via which the connection path to the subscriber who wants the remote connection is established in a known manner. A time zone counter ZW i for western traffic is assigned to each link. A long-distance line leading to the group selector GW8 in the remote distribution office VF is reached via the reversing selector UW 4. The setting of this selector and the group selector GW 9 is carried out in the same way as described above. If the group selector GW8 is set to the tenth decade (selection of a zero), the selector UW 4 switches over to a free trunk line leading via the changeover selector UW 5 in the distribution remote office VF to the group selector GW io in the world remote office WF. When this is set by selecting another zero, the selector UW S -in the distributor% rtiamt VT is set to one via the reversing selector UW6. mm ,, Grappmselfer = ler GW i. i for a special group size 2 : in the World Remote Office WF leading long-distance line. Thus, the distribution control center YF - a time-zone counter switched ZI3 ,. ftn left qn # .4nn d 'Prevention setup via UW6 and GW i2. for another group Gr.3 with Z14 being switched on by a remote officer in the same way as described above for the connection directly established by the sub-offices: The remote places, however, need to select two to three fewer zeros depending on their arrangement in the Emd- or Vertailerfernämtem .

The arrangement of the remote places in the remote distribution office VF can be done in the same way as it is shown in the drawing in the end remote office EF. Reversing selector and counting direction uvg <n can , however , but at the expense of the number of lines; can be saved if each remote link of a space has a double reversing dial instead of the single; in. the drawing designated with UWs, assigns: Via this first the group selector GW io is entered into group: i in the world remote office WF. Wound a zero chosen; This means that it is switched directly to a single group selector GW ii for group 2 with a simultaneous connection of a time zone counter ZI3 for this group. .When the group selector GW ii is set to the tenth decade. If the reversing selector in the remote distribution office VF is switched on again to one that leads directly to the group selector GW 12 of the third group of world-wide verdcehrsverhindungen Gr.3. Long-distance line. At the same time, the counting device Z14 is switched on while ZI3 is switched off.

In the production of long-distance deaths by officers can the charges determined by the time zone counters directly on the counters of the Participants, on fee displays at remote stations or on guide label printers will be charged. A transmission can also be made from the time zone counting devices the counting current impulses take place simultaneously on several of these elements. Likewise can for long-distance connections established directly by the participants, the respective Determined fee either on the subscriber counter or on a fee printer, If necessary, however, also on: both are offset at the same time.

The Number of zeros to be selected for long-distance and world-wide traffic will be reduced if d. the participants e.g. B. already through the first zero to zurr remote distribution office VF and can be switched through with the second zero to the world remote office WF.

The particular economic advantage of the invention results from the fact that long-distance traffic is only about 1 5 % and world traffic is only about 1 to 2% of the total of all long-distance connections. amounts to. For long-distance and world traffic, because of the good performance in large bundles, only an additional cost of around 8% on normal 7-zone meters, as they are known in various designs for local traffic, and has been in practice for a long time have proven themselves.
