Description

The invention relates to telephony, In particular to devices for monitoring the work of telephone exchanges.

Known devices that automatically make test calls at automatic telephone exchanges containing modules of pseudo-subscribers and pseudo-illuminators, trigger memory and a processing unit for measuring results (1). . However, these devices do not allow a large number of different connections due to the constant communication modules.

^Closest to the proposed device is an automatic ^ί5 test call at automatic stations, containing a switching unit of test subscriber sets connected to n subscriber sets, η sets of auto-subscriber 20 and η sets of answering machines connected to a switching block of test subscriber sets, as well as a unit dialing control and block test numbers, outputs 25 of which are connected to the inputs of the dialing control unit [2J.

However, the known device must have a large amount of equipment due to the constant connection between auto-jq transponders and auto-subscribers.

The invention is the simplification of the device by eliminating the constant connection between auto subscribers and answering machines. ₃₅

This goal is achieved by the fact that: in the device of the day of test calls at automatic telephone exchanges, containing a switching unit of test subscriber sets, ₄₀ connected to η subscriber sets, h sets of auto-subscriber and η sets of answering machines connected to the switching block of test subscriber sets, as well as the unit yn alignment dial ₄₅ and the block memory test rooms, which outputs are connected to inputs of a set of control block number, entered numbers and switching unit pytatelnyh subscriber, Sgiach sets, outputs of which soedi- ⁵⁰ yen to corresponding inputs dial number control unit which outputs are connected to respective sets avtoabonentov.

The drawing shows a structural ⁵⁵ electrical circuit of the device.

VNIIIPI Order 3934/51

The device contains block 1. switching test subscriber sets, subscriber sets 2y2 _p , sets 3 ^ -3 _p auto subscribers, sets 4 - answering machines, block 5 · dialing control, block 6 storing test numbers, block 7 switching numbers of test subscriber sets.

The device operates as follows.

In accordance with the communication directions selected for monitoring the connections, using unit 1, sets of 3 auto-subscribers are connected to the corresponding subscriber sets 2 selected as outgoing, and sets of 4 answering machines to subscriber sets 2 selected as incoming. Then, with the help of sets 3, the connections to the sets 4 of the answering machine® are automatically independently established, controlling the correctness of the completion of all stages of establishing the connection. In this case, block 7 is in the first position, and each of the subscriber sets 2, using block 5, dials the number of one of the sets 4 in accordance with the information received from the block 6 of memorization of test numbers.

After the end of all test connections, block 7 switches to the second position and provides information reading from the other output of block 6. Information through the dialing control block 5 enters the auto subscriber sets 3, which dial new numbers and establish new connections. For η changes polo. In block 7, η ² connections will be established between both incoming and η based on. your subscriber sets 2, i.e. all possible connection options.

During inter-station checks, the device works in a similar way, only connections are made to sets of 3 auto-subscriptions similarly to the device of another station.

Thus, the proposed device provides both independent control of incoming and outgoing directions, moreover, the number of contacts for switching subscriber sets can be reduced by a factor of several in comparison with the known device.
