Description

1 2

In telecommunication systems, in particular telephone systems, there are circuits for switching through to the central facility often the need to be locked out of a wide variety of tiing. This makes it possible to connect signal lines and / or switching devices on requirements according to their urgency in a to identify a specific promotion and to process the desired sequence one after the other, possibly for the completion of switching orders with 5 without the need for different identification units to be coupled to a central facility. required are.

For this purpose it is already known to itself- The circuit arrangement identified above

blocking, with the signal lines according to their, only a monitoring chain with switchover code number Multiple-wired chain circuits to enable different groups of markers to be used, the several simultaneous control circuits for different authorizations. Clearly identify claims one after the other. This arrangement is therefore only up to a certain point First, a classification element and a number of signal lines to be monitored and / first chain circuit a decade number of the identifying or switching devices with regard to their complexity confirming participant number and economically.

Then another chain ensures that of 15 exceeds the number of signal lines one beden Evaluation circuits of the downstream determined limit, so it is more advantageous to use a Schalkadenziffer only those can address who use the service arrangement, the thereby identified, The second digit belonging to the ext. decade number shows that next to the one monitoring chain Returns the decade digit. The disadvantage of this arrangement for checking the various markings is that the order in which they are dispatched is limited to the 20 circuits per signal line and / or switching device circuitry Structure of the chain connections, a further monitoring chain without Umnicht but depends on the type of requirement. Switching option for different marking currents important and only briefly pending request circuits are provided and that the evaluation circuits changes, e.g. B. electoral requirements, but it is westerly the chain switching elements of both monitoring chains worth seeing, they are compared to less urgent requests via multiple lines in the form of a matrix and indications, z. B. normal identification, privileged viduelle control contacts and decoupling diodes to clear. individual signal lines to be monitored and / or

The object of the present invention is to provide a switching device in pairs in any combination circuit arrangement to monitor the signaling can be switched in series, whereby as a result of mutual status of Sigriallinien and / or switch gear locking of the individual chain switching links in directions for the purpose of identifying or completing each surveillance chain, only one chain of Schaltaufträgeri can respond by a self-locking chain link. Through the further "over-switching to create their switching elements through the guard chain without switching option and the controlling signals without additional start-up or over-interconnection of the evaluation circuits via two monitoring devices are directly controllable, 35 dimensional multiple lines result opposite the requirements of different entitlements of the linear arrangement with a larger number of application classes, e.g. B. normal identification or election signal lines to be monitored a significant requirements are assigned, on the basis of which a saving of chain switching links. Correct order when handling several The principle of the invention and different balancing times pending requirements are defined 40 forms of management are now on the basis of examples and will.

For example monitoring of the signal state of η signal lines, signal lines to which a low and / or switching device with two authorization codes is assigned can be shown in front of signal lines with high classes. The individual key figures assigned to them are processed. However, if there are request relays (AN or W) with their requirements with different authorizations, the conso controlling 65 switching elements of the monitoring chain will cycle those marking circuits first are selected in the units Al to An , which are grouped together with the highest authorization class. The monitoring chain is divided in such a way, while all the other marking current switches, that when a chain switching element responds

For normal requirements in FIG. 2 of the chain switching element Zl brings the relay D of the evaluation circuits formed, which via the line 11, device A1 to pull the signal line or the first winding of a chain switching element, through a switching device 51 to the central device through the contacts IzI to 1 zn, switches via the contact IzA. If this has carried out the corresponding switching orders such as the idle side of the common control contact, it switches by throwing the Re-3 ° wa run. In the case of requests with priority lais AN in the unit .41, the monitoring chain is switched to evaluation circuits, which are released again via, whereupon the next request , the second winding of a chain switching element Z, is dealt with. via one of the contacts 4z 1 to 4z «, via the Kon-Es the function of the circuit is now running when there is clock 2zh as well as via the working side of the control con of a request with the second, higher authorization clock wa .

The relay W on. This brings with one of its contacts the arrangement according to FIG. 3 is for 109 signal lines, the relay WA, the response of which is a criterion that 4 ° their individual switching and control elements in unity is for the fact that at least one request with privileges A 11 to A 03 are combined and that two are authorized. This means that all contacts' authorization levels are designed.

If, at the same time, a request were also arranged with the crossing points of a matrix, the first, lower authorization level of which is pending, rows / 1 and / 2 can be switched and no evaluation circuit (1) can be formed for the tens, since chain Kl lead while the columns have a simple one on the one hand only have the line to the individual monitoring chain K2 in the corresponding unit Ax . Contact is on, but contact w is not closed. The individual marking lines are decoupled from one another by means of diodes, but line / 1 is mutually decoupled.

In our case, this energizes relay El , which, with its contact el, switches the signal line with unit A 11 to the central unit through the individual relay D. If there are several equally valid requirements, they are first assigned within a group of ten by the chain Kl, but the groups of ten themselves are again in the chain Kl one after the other in accordance with the sequence shown in FIG. 1 and 2 respectively selected. In the event of a request with higher authorization, the circuit in Fig.l is switched from the marking circuit / 1 to the marking circuit II , and the contacts also come in the corresponding units Axx. This again ensures that only evaluation circuits are closed for requests with priority.
