Description

GERMAN

The invention relates to a marking device for telecommunication, in particular telephone system !!, in each of which the group and individual identification switching means with a common blocking line provided and the individual identification switching means on identification lines assigned to them are switched on for successive detection of. marked by a given potential, certain participants, connecting lines or other associated incentive lines., which each have an ohmic resistor and non-linear resistors connected to it in parallel are connected to the associated identification lines.

Identification devices with group and single identification switching means for marking the setting of connecting elements are already known, in which the blocking potential is supplied in such a way that when a combination of identification switching means corresponding to the desired connection is responded, the remaining identification switching means are activated with the aid of non-linear resistors. be blocked. If, for example, it is η identification switching means within a group, the others are to be blocked. Identification switching means of this group η (n-l) non-linear resistors required, ie 180 non-linear resistors are required for 100 units to be identified, namely 90 for the tens and 90 for the single identification switch means. In addition to this relatively high cost of non-linear switching means, the aforementioned arrangement also has the disadvantage that special auxiliary switching means and various potential sources are required.

The object of the invention is to avoid the disadvantages mentioned, and in particular reduce the relatively large number of non-linear resistors. This is achieved by that when a labeling incentive occurs and one of the associated combinations is addressed corresponding identification switching means not the supply of the blocking potential for the rest of the Combination associated switching means takes place via a changeover contact of the relevant switching means.

With the arrangement according to the invention, for example, in a marking device for 100 units 160 non-linear resistors saved with additional expenditure compared to the known Arrangement of only 20 relay contacts.

The invention will now be described in greater detail on the basis of exemplary embodiments with the aid of FIGS. 1 to 3 explained, however, only for the understanding of the identification device

In the identification device shown in FIG. 1 in the form of a marking matrix, which is used to identify 100 units, for example to mark the setting of 100 subscribers or connecting lines associated with connecting organs, the incentive lines associated with the subscribers or connecting lines are connected to the connection points 11, 12 .. .

Diodes acts, and the quiescent side of the contact belonging to the corresponding identification switching means, the blocking line SPz for the tens and the blocking line SPe for the ones are switched on. The blocking potential (-) 'for all switching means required for a different identification is applied via the working side of the relevant changeover contacts.

Both relays respond and identify in a known manner by a suitable combination of the associated contacts. by. Marked earth potential. Point or the setting of the point 11 and thus the associated one through the contacts of the identification switching means Zl and £ 1. Line corresponding liaison body marked. During the marking or m arider process, the ao other marking switching means, which do not correspond to the combination of point 11, are connected to the blocking lines via the switching contacts 2 11 and irll!

If a further identification or setting incentive occurs at any point during this time, this incentive is held in waiting until the energized switching means Zl and. El are in rest position again :. In this way, the individual labeling or connection incentives are processed one after the other.

If two or more points 11 ... (00) are now simultaneously marked by applying earth potential, the associated Z and Ε relays are initially excited. If, for example, ground potential is simultaneously applied to points 11 and 23, the relays Zl, Z 2, £ 1 and £ 3 are accordingly excited. If one of these relays picks up faster than the others, this penetrates with its marking. For example, if £ 3 addressed first, it puts his.

The remaining £ relays are thus bridged with low resistance to minus and can no longer respond. A current now flows from point 11 via Dell, the identification line e 1, Del, e31 to minus. This will raise the potential. the point common to the resistor Will and the decoupling diodes Ds 11 and Dell is lowered so that the relay Z1 can no longer respond. It can therefore only attract the relay Z2, so that the point 23 is clearly defined. In the event that the relay Z 2 has addressed first, it is, in a corresponding manner via the contact 3 21 and the inhibit line SPs negative potential to the other Z-relay and the diode Dsl, Ds3. . .

If the case now occurs that two or more tens or ones relays respond at the same time, so these close due to the supply of the response potential about their rest contacts from each other.

FIG. 2 shows the same arrangement as FIG. 1, only in a simplified representation.

The labeling device shown in FIGS can now be expanded as required, in Fig. 3 is a marking device shown in the representation according to FIG. 2, which offers the possibility of Points with the help of three groups (100, 10 and 1 relays) of identification switching means to mark. The mutual blocking is achieved in a completely analogous manner, as described with reference to FIG. 1.
