In telecommunications, in particular telephone systems, that the beer give regardless of further manipulation Often there are operational cases whose other participants are participants in the existing connection path action a knowledge about which a certain one is held on at the moment and therefore independent Connection involved participants, connection of a possibly occurring triggering too requires facilities and sections of the path. Such 5 will be checked at a later date Operational cases are given, for example, when im can.

Operating mode for those involved in a connection is or if the annoying subscriber in the case of call annoyance, it does not matter whether they are called or calling subscribers should be determined. io are the participants, and regardless of whether the

In order to solve this problem, in particular, the failure reports for various reasons are based on modern telecommunication systems with devices. Thus, according to a further development of the Erfinger, an automatic connection path enables the issue of the fault report by the tracking, in such a way that the called subscriber is evaluated as a catch command in a known point of the comparative sense to be determined, where such a connection path an alternating test voltage is switched on if necessary by a rating in the control center and then gradually depending on the connection level to the stored capture authorization, connection level all possible connection paths while in the other case or when issued by the recipient with the presence of the test change callers Participants who are rated as such will be searched for tension until all facilities and communication paths involved in the marking ao and the checking of the recorded connection path result.
Sections of the way are determined. Should the submission of an examination of the

Furthermore, there is (German Auslegeschrift 1239 741) the standing connecting route after it already with regard to telecommunication systems in which fault reports from both the calling and the information for 35 called subscribers is possible for the duration of a connection, so are for the existing connection path is saved before the two occasions for the fault report are different An arrangement has been proposed that requires the identification numbers to make a catch order safe according to can be recognized in the context of a connection route tracing.

In accordance with the prerequisites, what can be done in a known manner during each event. For the connection of the call numbers and serial numbers in this case, too, several operational options for the subscriber accounts involved in this connection are conceivable. The simplest is that unbinding devices and sections of the route are stored in the memory immediately after the connection routes of the central control ZST have been recorded. The intermediate data the subscribers involved in the connection storage of all connection data is activated again, regardless of whether this is necessary solely so that at the end of one of the remaining connection paths is also triggered. Connection this can be triggered again. The calling subscriber can therefore immediately after doing this, it is irrelevant whether in the context of an issue of the fault report attempting to solve the existing connection path to the full io desired subscriber is unlocked on another connection scope or whether only to reach the paths.

The command for such a recording is indicated in the work of the switching system X by one of the connection paths on the connection in question. First of all, it is assumed that the subscriber involved, by choosing a specific one, is given the subscriber Λ via the out code number, which is connected in a known manner to the outgoing transmission via the V-AV or T-AV transmission EVS from where the connection is monitored. In this way, all can be subscriber-dungsweg via the connecting line VL to Verabhängigen fault messages, regardless of whether it's 30 connection kit EVS of the Office Y leads, which in turn is easier to be a real disorder or a catch command over the extended connection path of the line Is in the same Wise and with extremely network KN to carry out this office with the subscriber C with little effort.

Based on the two possible cases of operation, require more than the connection set EVS and the partial control of a message by the subscriber, V-AV, the Durchnämlich when a called party to circuit 40 of the dot chain by anonymous in line network KN calls feels harassed by the central control ZST or if an animal drawn connection path causes. If there is an actual disruption to the connection path, the existence of this connection path results in several operational options, depending on the subscriber A of the previously existing connector, whether only a single connection path to the EVS connection set is separated and code number or two separate code numbers for 45 instead via the connection set IVS with which the fault report is permitted. subscriber-side connection of the test station PL

In the first case, however, a clear release. Such a solution, however, only appears to be able to make a decision as to whether a catch command is expedient when the fault report is issued or a request to check the calling subscriber and only then is there is a standing connection path Desired participant has not yet been able to submit a review of the registration. During the existence of a reconnection path leading to a disruption message, the called subscriber is limited to the calling subscriber alone, which is separated and therefore does not matter further to further events, as such dragged what is often perceived as a disruption. Malfunction reports anyway to a predominant part 55 Furthermore, there is also the fact that the called subscriber usually starts from the calling subscriber. In the case of unnecessary blockage, although with a real recording of the dialed code number due to the disruption of the connection path the further upright corresponding partial control, e.g. V-AV, the maintenance of the connection and thus the continuation only has to be distinguished whether this code number is not worthwhile from the call . In the event that the called subscriber or the called subscriber has already reported back to the calling subscriber, it has been sent. therefore it is more appropriate that an intrusion through

In the case of a catch command, the test station can take place, so that the called part of the group can also do so Recording of the associated route data and the user remains in contact with the test station, in particular the call number of the calling part The resulting connection path is

the failure report should be viewed as completed 65 in the line network KN of office X with a dashed line. If, on the other hand, it is a real fault, namely subscriber A is aware of his or her message, a subsequent check of subscriber circuit TS via the line network of the recorded connection path is required, KN and the test station PL for the outgoing connection.

connection set jEFS ^{1 of} the existing connection. The test station PL is looped into the existing connection path like a connection set, so that there is a possibility of speaking with the calling subscriber Λ as well as with the called subscriber C. In this case, the subscribers involved in an existing connection are only activated after the fault report has been received by the test station PL and, appropriately, by the latter itself.

The check of the connection path reported as disturbed can now follow immediately or also at a later point in time, since all of them are recorded through the recording

The connection route data determined in the connected office are then shared Recording point forwarded, expediently the end office delivering the recording command 5 each serves as a common recording point. The transmission of the line route data can also take place both via separate data lines and via the existing connection path. Independent of this, a non-office-bound central recording point can also be used, in the exemplary embodiment the recording point Z may be provided.

In relation to the selected exemplary embodiment, the following functional sequence results:

the information necessary for this has already been ensured. 15 of the office X with the participant C of the office Y ver-Until the final review of the as disturbed is bound. If subscriber A now chooses the fault-reported connection path, this remains, apart from the code number, which is expediently forwarded to office Y via the connection line VL even after the subscriber has been activated, then it is blocked after detection. This can in the embodiment z. B. the malfunction code can be carried out by the sub-controls V-AV in such a way that the route search used for 20 of the recording command to both central controls forwarded the occupancy status memory ZST , and the associated connector central control ZST, the occupancy state dungswegdaten containing memory sections of the in all Path sections of the line network KN stored in the two central controllers contain storage units which participate in the disturbed connection and are controlled. The lost route sections incurred in office X even after the connection route data has been triggered will be marked as still occupied immediately via the indung and the formation line bundle JL and the output sub-control A-UE will be sent to the printer DR . The connection data in the central control ZST of the office Y, on the other hand, are forwarded via the 30 information line bundle JL to the sub-control D-UE , which automatically controls the forwarding of the connection data over the data line DL to the office X , where it is controlled by a corresponding sub-control D-UE recorded as disturbed reported connection routes one after the other and forwarded via the output sub-control to the printer DR of the route sections and facilities involved until they are forwarded. The assignment of the blocked by both review. Offices X and Y data coming can be either

Offices without saving the connection route data. The record of both offices is carried out

In both cases, the data in a central point Z, the recording command given via the fault code number and the output part control A-UE in the two offices indirectly forwarded to the connected offices, 45 via switches w , is omitted, in both cases directly over the existing connection a transmission of the communication path incurred in the office Y or also over separate data lines connection path data over the data line DL. The data to be recorded with simultaneous identification are instead transmitted directly via the connection path in Office Y. In the case of similar offices, the output part control A-UE is provided directly to this, the identification is expediently forwarded via the existing central office and from the receiving connection path, e.g. B. VL in the embodiment, control transmission ST of the recording device so that they are from the corresponding sub-control, z. B. DR passed. The same applies to the submission of a V-AV, which can be recognized in the same way as a fault report by subscriber C in office Y, a recording command originating from the same office regardless of whether a real fault message and therefore the storage locations for the associated 55 is present or whether only the called subscriber for route data within the storage facility is the central interception.

However, it is advisable to take additional measures to identify fishing connections. These additional measures appear particularly necessary when the participant to be caught calls from an exchange without storing the connection route data. These measures exist that on the one hand the authorization to catch as a subscriber-specific identifier in the tracing connection is stored in the context of a search pre-65 central control, so that already ganges and identified by the connection before switching the connection to a catching device from step by step, participants authorized the office of origin will follow. can be informed that it is where appropriate

In the case of connections from or to an exchange without storing the connection route data, however, it triggers the recording command consists of a conventional type of connection route tracing by first using the to

is a catch connection and accordingly preparatory measures are taken to enable catching of the calling subscriber if a catch command should actually follow. The corresponding information can likewise be transmitted either via the connecting line VL itself or via separate data lines. This again results in the following options:

1. Immediately after receiving the notification that it may be a fishing connection the calling party is identified in the originating office and this number is entered in the Transfer office of the called subscriber, where it is then immediately available, if the catch order should be issued.

2. Together with the transfer of the criterion that it is possibly a safety connection acts, the number of the called subscriber is also in the office of the calling Subscriber transferred, but the identification of the calling subscriber only when the Catch command carried out and then together with the number of the called subscriber recorded.

3. After the catch command has been issued, the numbers determined in both offices are combined with an identifier of a central office that enables the assignment, e.g. B. Z in the embodiment, transmitted.

The same applies in the event that the catch command is issued by a participant who is sent to an office with storage the connection route data is connected.
