Description

The invention relates to telecommunications, and in particular to telephone communications, in particular, to devices for monitoring communications at coordinate-type automatic telephone exchanges (ATS K).

Currently, coordinate exchange exchanges are used in Russia, mainly ATSK, ATSK-U, PSK-1000. ATS K contains mainly a subscriber kit, a contact field with markers, as well as outgoing and incoming cord sets. The contact field of existing ATC K consists of groups of contact springs of relay type with contacts for closure - multiple coordinate connectors of the ISS, and the management of switching devices is carried out using station-wide registers and markers. The choice of direction and the search for a free line is carried out by a marker that controls the communication device., Which contains a caller of the calling input, a determinant of the desired direction of communication, a device that marks free intermediate lines for connection, a test device, a switching device and a control device. ((B.S. Goldstein Switching Systems, St. Petersburg: BHV-Saint-Petersburg, 2003, p. 63-77)

ATS works as follows. When a telephone is removed from the device on the PBX in the subscriber set, the AK draws the anchor of the linear relay L and sends a request (signal) to the outgoing cord set (ISK) to the line of the calling subscriber to the marker of the subscriber search level of links A and B (MAI AB). At this request, the MAI AV marker determines the caller’s line (the caller’s line number is marked in the marker by triggering the corresponding decimal relays and unit relays), selects a free intermediate path between the ISS A and B links and the ISK. which has at least one ARB subscriber register free, as well as a free search marker for MRI and a marker for a group search for MGI.

After determining the free HMI, the MAI AB marker includes the A and B links that select and hold the electromagnets of the ISS, so the HMI is connected to the caller’s line. At the same time, in the subscriber set, the isolation relay P attracts the anchor. Then the MAI AV marker is turned off, and the ISK sends a request to MRI to connect the ARB register. MRI determines the HIS (the tenth relay and the unit relay are activated), waiting for the register to be connected, searches for a free register and turns on the corresponding select and hold magnets of the ISS RI, through the field of which the register is connected to the HMI. Then MRI is turned off. Having received the station response signal from the register, the subscriber proceeds to dial the number, all of which are recorded in the register. The connection is controlled by tokens, which for this purpose request a register about the dialed number. The exchange of information between the register and markers is carried out by the frequency method according to the “shuttle” method. At the same time, the applied ATSCs need constant improvement, in particular, by expanding their functions.

The technical problem solved by the author was the modernization of ATSK by equipping it with a time-based system, recording and measuring the duration of all outgoing telephone connections of subscribers

The technical result was achieved by the inclusion between the marker and the outgoing cord kit of the additional module. The module is connected to the marker wires, through which information about the subscriber number (AD) and contacts on the IPTC are received, which are most convenient for connection. As the latter, they use, as a rule, the bottom wires of IShK (TP). The module is a hardware-software three-level system controlled by computers compatible with IBM PC. The module provides registration and accounting of data on all outgoing connections initiated by subscribers of a 2 thousandth subscriber group (or group of a different capacity, depending on the type of telephone exchange). The module consists of the following blocks and nodes:

- secondary power source

- processor board

- floppy and hard drives

- network board.

If necessary, the module contains demultiplexers that are inserted into the free slots of the module’s cross-board and connected to the multiplexers using connecting six-core or eight-core cables and WESTERN telephone jacks.

The general module connection diagram is shown in Fig. 1, where the following notation is introduced: 1 - block of the 1st level; 2-marker; 3 - ISHK; 4 - multiplexer; 5 - module: 6 - block of the 2nd level; 7-technical supervisor; 8 - supervisor; 9 - modem; 10 - block of the 3rd level; 11 - server; 12 - computer NT Server; 13-workstation

Individual elements of the system perform the following functions. Module 5 for monitoring a level 1 station - monitors the operation of the station equipment and records information about its status. To interface the module with the PBX equipment, multiplexers 4 are used, which are installed on the main equipment of the PBX and connected to the corresponding (depending on the type of the PBX) points of removal of inflection. At the second level (block 6), the supervisor computer 8 is in communication with the Level 5 modules 5, receiving Toll-ticket data from them and storing this data on its hard drive. At the facility where several telephone exchanges can be located, one computer is installed - the supervisor. Technical Supervisor 7 - performs the functions of technical supervision, providing diagnostics and signaling the status of modules, as well as individual devices of the PBX and is installed on each PBX.

At the third level (block 10) there are two types of computers: NT Server 12 and workstations 13. These computers are designed to monitor the state of the entire network and provide access to data on telephone conversations and other connections. NT Server 12, installed on the telephone node, collects and stores all the credentials accumulated on second-level computers 8.

From the point of view of functionality - computers of the second and third levels can be networked, because all computers have a server function, but at the same time, are clients of all other computers.

The principle of operation of the system is based on monitoring changes in potentials at the points of connection of the system equipment to the PBX equipment during the following stages of establishing a connection:

- removal of the handset;

- dialing the called number;

- response of the called subscriber;

- hang up by any subscriber.

As a three-level control system, the ATE plus system or its individual elements can be used in particular.

For certain types of stations, the following versions of the ATB plus system can be used: ATE plus / ATCK - for automatic telephone exchanges with an ATSC coordinate connector; ATE plus / ATCK 100/2000 - for automatic telephone exchanges with an ATSC coordinate connector; ATE plus / ATCKY - for automatic telephone exchanges with an ATCKY type coordinate connector; ATE plus / ATSP - for automatic telephone exchanges with a coordinate connector of ATSP type; ATE plus / ACjK - 55 for automatic telephone exchanges with a coordinate connector of the ACjK - 55 type; ATE plus / TICKt - for substations with coordinate connector type ПСК 1000.

Figure 2 shows the connection diagram of the MAV ATE plus multiplexer according to the claimed scheme to ATSK; figure 3 - connection diagram of the multiplexer IShK ATE plus according to the claimed scheme to ATSK, ATSKU.

In this case, the following points are used: 20 wires "a1-a20" - to determine the dialing of subscriber number B; 10 wires E1-E0, 10 wires D1-D0 - to determine the dialing of the caller A; 10 wires G1-G6 and P1-P4 - to determine the outgoing set of HIC on which the call is being made; 2 wires IP and PA - to determine the start of the start-off of the handset and determine the number of the subscriber A. When connecting the ISHC cabinet, use 40 wires "f1-f40" to determine the response of the called subscriber, determine the established connection and hang up.

The advantages of the claimed technological scheme is:

- work in real time

- central supervision of all system functions

- on-line diagnostics and signaling of the status of PBX devices

- flexible billing of all types of outgoing connections

- on-line research of calls directed to the observed numbers

- statistical processing of the outgoing graph according to various criteria

- the ability to easily integrate with other systems available to the telecom operator

- the equipment is designed for continuous and round-the-clock operation without the constant presence of technical personnel.
