Description

The invention relates to communication technology and can be used in automatic telephone exchanges (for fixing a telephone load) / in data acquisition devices and in cost accounting equipment (for fixing phases and duration of communication sessions).

A device is known for registering a telephone load / containing P fixing nodes, containing memory blocks (where n is the number of fixed telephone kangshovs), with the outputs of the fixed nodes connected to the inputs of the corresponding elements OR tl.

However, the known distribution registers an inadequate amount of information.

The purpose of the invention is to increase the recorded information.

To do this, a device for registering a telephone load containing n fixing nodes containing memory blocks (where n is the number of fixed telephone kangshovs), where the outputs of fixing nodes are connected to the inputs of the corresponding SFDs. OR, the comparison units are entered into the fusion unit, the first the inputs of which are connected to the outputs of the respective memory blocks, and the second inputs are connected to the first inputs of the memory blocks, and the third inputs of the comparison and interrogation blocks are additional inputs of the locking nodes, The outputs of which are the outputs of the comparison and interrogation blocks.

In addition, the unit of comparison and

10 interrogation comprises two elements AND, the first inputs of the first and second elements AND being connected and being the third input of the comparison and interrogation unit, the second inputs of the first and second

The 15 And elements are connected inversely and are the second input of the comparison and polling unit, and the third input of the first element And the inverse input of the second element And are connected between

20 is the first input of the comparison and interrogation unit, the outputs of which are the inverse outputs of the elements I.

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

The device contains fixed nodes 1 containing a memory block 2,

30 elements OR 3, blocks 4 comparison

and polls that contain two elements AND 5 and 6.

The device works as follows.

When a polling signal arrives at the polling input of the locking node 1, the output signals of the corresponding block 4 appear, determined by the result of comparing the signals available at the information input of the node 1 and the output of block 2. Signals from the outputs of the 4 pass through the OR 3 elements to the information device outputs. In the initial state, when the signal at the information input of one of the nodes 1 is missing and the corresponding block 2 is in an inactive state, the signals at the information input and the forward output of block 2 are equivalent, and during the polling of the said node 1 signal at the outputs of block 4 are missing. When a signal appears at the information input of node 1 (the occurrence of a telephone load), the state of the information input and the direct output of block 2 become unequal and during the subsequent interrogation of node 1 at one of the outputs of block 4, a signal appears corresponding to the initial phase (occurrence) telephone load.

When polling the next node 1, the enabling input of the block 2 of the previous fixing node 1 receives a signal allowing the block 2 to receive the state of its information input. The block 2 switches to the active state. In this case, the signals at the information input and the direct output of block 2 again become equivalent. During the surveys of the considered fixing unit 1, there are no signals at the outputs of block 4. With the disappearance of the signal at the information input of node 1 (the disappearance of the telephone load) the state of the information input and the direct output of block 2 again become unequal, and during the subsequent interrogation of fixing node 1, a signal corresponding to the final phase appears at one of the outputs of block 4 (disappear) telephone load.

When polling the next fixing node 1 to enable the input of block 2 of the previous fixing node 1, a signal is received allowing the block 2 to receive the state of its information input. Block 2 enters the inactive state. At the same time, the signals at the information input and the direct output 2 again become equivalent. During subsequent multiple polls of the fixing node 1 under consideration, there are no signals at the outputs of block 4 until the information input of the fixing node 1 is again not present. a signal appears indicating a telephone load has occurred.

Thus, the introduction of a new element and the corresponding links allows obtaining and recording additional information about the phases of telephone load.
