The invention may find applications in a centralized or decentralized system for the technical operation of urban telephone networks.

The purpose of the invention is to improve the accumulation accuracy and simplify the device by eliminating the block of polling of the state of the memory block.

The drawing shows the structural electrical circuit of the device for accumulating statistical information from the telephone station of the coordinate system.

The device comprises initiating signals switch 1, control unit 2, external signals switch 3, internal signals switch 4, buffer memory block 5, code converter 6, memory block 7 and indication block 8.

The device works as follows.

By initiating signals are meant signals that mark individual objects in PBX equipment, information about the operation of which is to be accumulated and processed in this device. These are sort of applications for service, coming from registers, directions of communication in which connections are currently being established, etc. These initiating signals are transmitted to group objects, for example, a station code analyzer (ACU) or / and an automatic control device (ACC), which is scanned by the initiating signal switch 1. These group objects are connected to the device by group wires, to which each individual object, transmitting the initiating signal to the group object associated with it, gives information about its number. This makes it possible, with a positive scan result, i.e. when the initiating signal switch 1 encounters the initiating signal, immediately read the device number (address) of the individual object that has submitted the service to the device from the group wires. This last information is for the device the so-called external signals and the 3 external signals are fed to the switch. The switch 4 of the internal signals is designed to redistribute the incoming signals from

various storage units.

The output of the initiating switch 1, the inputs of which receive the initiating signals, is connected to one of the inputs of control unit 2. One of the outputs of block 7 is connected to the second input of control unit 2. The outputs of control unit 2 are connected

with inputs of the switch 3 external signals, switch A of the internal signals, block 5 and converter 6 codes.

To the inputs of the switch 3 external

The signals are connected to the control buses of the PBX (not shown), the output of the switch 3 is connected to one of the inputs of the switch 4 of the internal signals. The second input of the switch is 4 internal

the signals are connected to the output of the converter 6 codes, and the third input of the switch 4 is connected with the output of block 7.

The output of the switch 4 internal signals connected to the input of block 5,

the output of which is connected to the input of the converter 6 codes. The output of the converter 6 is connected not only to the input of the switch 4 of the internal signals, but also associated with the inputs of the block

8 indication and memory block 7.

In the proposed device, at least three modes of accumulating information are provided, as well as polling and summarizing modes carried out

in these accumulation modes. The transition from one mode to another is carried out using a control switch (not shown).

In the first accumulation mode, the proposed device counts the number of outgoing calls, which makes it possible to obtain the distribution of the incoming outgoing load from the particular PBX on which it is installed, which

all PBX network. On the basis of this real load, it is possible to determine, for example, the coefficients of tons of subscribers in a given station in a telephone connection with the subscribers of each of the network stations.

In the second mode of accumulation, the device makes it possible to assess the quality of customer service in the directions of outgoing communication.

in the third accumulation mode, the proposed device registers the operation of each relay of the latches of the first three digits of the number in the subscriber registers of this coordinate

A PBX and in one of the varieties of this mode reveal those relays, the intensity of which is different from the average.

In each of the noted accumulation modes, it is possible to poll accumulated information with its display on the site or in the center of technical operation (CET). In this case, the survey can be carried out specifically according to the selected PBX operator (individual survey), and it can go through the entire memory of the device with indication of unsuccessful (from the point of view of accepted criteria) directions revealed as a result of the surveys.

When a summation mode is performed — in any accumulation mode — the accumulation itself ceases for the duration of the summation.

If the proposed device accumulates, for example, information in the first mode, then summation allows one to obtain, in particular, the final result of the accumulated information on all PBXs of any selected 100,000 Wells or any millionth zone of the network. Thus, there is a traction of nodes and zones, which can be used in the design of network development.

The device has a self-monitoring mode, which is carried out by simulating the initiating signals, inputting them into the switch 1 and controlling the response of the device to these signals.

To implement these modes, it is necessary to divide block 5 into two

5, emzones - the first 5, and the second bone each in eight four-bit words. The first zone is mainly used to record information received from the PBX equipment (address-45 of other devices.

individual objects marked with initiating signals), and the second - for output to the block 8 of the indication of the address of the individual object and the corresponding information accumulated in block 7.

The selection of the required zone in block 5 is carried out by block 2 in accordance with the drive operation algorithm. At the same time, unit 2, control of senior 55 services (individual and group address block 5, according to polls, summation and self-compliance with the operation algorithm, choose a control), which significantly reduces the first zone of block 5 by enforcing the complexity of the service PBX.

installation on a higher address bit, for example, a zero potential or the second zone of block 5, by forcing a + 5V potential on a higher address bit, for example.

The use of block 5 divided into two zones in the device allows for the simultaneous accumulation and interrogation of information about the devices or directions under investigation with the initiation of the results of the current accumulation or survey on digital indicators.

The technical and economic effect of the device is as follows: the amount of equipment is reduced at least 20 times, the number of connecting wires is reduced at least 5 times, with a corresponding decrease in the labor intensity of the installation, the cost is reduced at least 10 times, due to the expansion of functional the capabilities of the device, the targeted use of recovery resources and a more convenient system for viewing the results of accumulation and information processing, the maintenance labor intensity is reduced by at least 2 times.

These advantages are achieved by increasing the total capacity of the counters by no less than 300 times while maintaining the number of used counters (500).

In addition, the device allows for end-to-end monitoring of the network of coordinate PBXs (end-to-end monitoring is the assessment of the quality of service not according to the search, but along the path as a whole) and provides detection of faulty sections for processing statistical information on these areas using

The device automatically sequentially detects directions, the quality of service in which does not meet the established standards, as well as the relay of the latches of the subscriber register, the intensity of which is different from the established criteria.

The device has a number of
