Description

The utility model relates to the field of automatic telephony, in particular to telephone digital automatic telephone exchanges (DATS) for use on urban, rural, departmental and dedicated networks.

The utility model can be used as: an office-production automatic telephone exchange with the functions of digital integrated service networks (ISS), substations of city telephone exchanges, back-and-back telephone exchanges, rural telephone exchanges, dispatch and exchange telephone exchanges with dispatcher consoles, as well as subscriber digital hubs , signaling converters, channelization equipment and flexible multiplexers, equipment for access to IP networks.

A device known as “Digital automatic telephone exchange (DSC)" Elcom "(Technical description IKV.03.00.000 TO, version 2, Rus Tel Kom St. Petersburg, 2003), containing a switching module (MK), and digital connected to it channels are terminal modules consisting of analogue subscriber line modules (MAAL) and subscriber trunk module (MASL) modules, as well as an operator module.

The switching module is used to control the system and spatio-temporal switching of digital channels.

The module of analogue subscriber lines allows you to connect up to 100 digital subscriber lines, up to 200 standard two-wire analog telephone sets, as well as connect subscriber units designed to work in a digital integrated service network.

The basis of the work of the Elcom TSATS is the principle of temporary channel multiplexing and the pulse-code modulation method.

The essential features common with the claimed device are the switching module (in the claimed device, the control module) and terminal modules (expansion modules).

The reasons that impede the achievement of the technical result are the following disadvantages of the analogue:

- due to its orientation, the Elcom DATS is more suitable for use in public switched telephone networks (PSTN) than in departmental networks, its circuitry has limitations in the form of distributed power supply for the units, which does not allow power supply of the DATS from various primary power sources, which is different for different departments;

- the board of the subscriber complexes of the Elcom TSATS is built using SLIC microcircuits with a standard supply voltage of 48 V. Moreover, the microcircuits are not galvanically isolated from the lines. When switching from old analog exchanges to the Elcom digital telephone exchange, some telephone sets (TA) of subscribers will be inoperative;

- MAAL terminal modules allow installing 10 blocks of AK-25 subscriber complexes with a total capacity of 200 subscribers. At the same time, MAAL connects to the MK56 switching module with just one digital channel with a transmission rate of 4096 kbit / s. This limits the load capacity of the plant as a whole;

- TsATS "Elkom" does not support the operation of system telephones;

- The Elcom DATS does not include units for organizing the JCC 64 kbit / s G.703 interfaces, and also does not have V.35 / V.36 / X.21 / RS-530 / RS-530A / RS- interfaces 449, which will require the installation of additional third-party devices to implement these joints and interfaces when included in departmental communication networks. This introduces, in addition to the additional costs, restrictions on remote monitoring of the status of these devices and their management;

- The Elcom DATS does not include devices that provide packet Ethernet protocol information over the E1 stream. The implementation of such a function for inclusion in NGN will require the installation of additional third-party devices.

- installation of digital and analog termination blocks in TsATS “Elkom” requires the use of various types of terminal modules - MAAL, MASL, ME1, which complicates the general design of the TsATS and further operation of the station.

- in the Elcom TSATS, the functions of Autoinformer and SORM are performed by a separate MK56 communication board with a personal computer with a Pentium processor. For station options without SORM functions, this board will still be installed (for the implementation of Autoinformer, which leads to additional hardware costs.

- there is no “Conference Call” mode in the Elcom TSATS;

- In the Elcom TSATS, only one version of the primary supply voltage is used - 60 V.

The Sigma-SPb TsATS device (Digital ATS for Rural Communications, edited by V. G. Kartashevsky and A. V. Roslyakov, EKO-TRENDS, Moscow, 2003) is also known, containing a digital channel switching module and terminal modules connected to it via PCM-30 paths, consisting of input-output port (MVP) modules, as well as an operator module.

The switching module (BSK) is used for spatio-temporal switching of digital channels and system control. The input-output port modules (MVVP) are designed to connect analog subscriber and trunk lines.

The principle of the time channel multiplexing and the method of pulse-code modulation are the basis of the work of the Sigma-SPb TsATS.

The essential features common with the claimed device are the switching modules (in the claimed device, the control module)

and input-output port modules (expansion modules in the inventive device).

The reasons that impede the achievement of the technical result are the following disadvantages of the analogue:

- in the Sigma-SPb TsATS, the control bus in the MVP module is a “common bus" for all peripheral units installed in the cartridge. This circumstance does not allow the replacement of failed blocks during operation, and also reduces the reliability of the entire module, because failure of one of the peripheral units may damage the control system of the entire module;

- MVP modules in the Sigma-SPb central exchange are connected to the central switching modules with two PCM-30 paths, which limits the load capacity of the station as a whole, because in this case, some connections (for example, between subscribers of one MVP unit and another MVP unit) may be blocked;

- The Sigma-SPb TsATS does not include units for organizing the JCC 64 kbit / s G.703 interfaces, and also does not have V.35 / V.36 / X.21 / RS-530 / RS-530A / interfaces RS-449, which will require the installation of additional third-party devices to implement these joints and interfaces when included in departmental communication networks. This introduces, in addition to the additional costs, restrictions on remote monitoring of the status of these devices and their management;

- TsATS Sigma-SPb supports only one type of system telephone sets;

TsATS Sigma-SPb does not include devices that provide packet Ethernet protocol information over the E1 stream.

Of the known devices, the closest to the claimed utility model is TsATS “Kvant-E-Sokol” (Operation manual YYAO.122.030 RE, Belgorod, 2002). The prototype works on the principle

Blocks of digital trunks are designed to connect streams with pulse-code modulation of digital trunks. Trunk blocks are designed to connect to oncoming PBX trunk lines.

The capacity of the digital switch TsATS "Kvant-E-Sokol" is 32 × 32 group paths. When forming a PBX for several thousand numbers, a large number of such digital switches will be required.

The essential features common with the claimed device are: a digital switch (in the claimed device, a switch), a processor connected to a computer (in the claimed device, a processor module connected to an external computer), a switching and pairing device (in the claimed device, a control unit and switching), a tone generator (in the inventive device, a tone generator), an acoustic signal generator (in the inventive device - autoinformer), a clock generator (in the claimed device - clock), blocks of subscriber lines, the outputs of which are connected to analog subscriber lines and analog connecting lines (in the inventive device - blocks with

subscriber sets, the outputs of which are connected to terminal telephone subscriber devices), blocks of digital trunk lines, the outputs of which are connected to streams with pulse-code modulation of digital trunk lines (in the inventive device, blocks of digital termination of lines with pulse-code modulation, the outputs of which are connected to external digital streams), blocks of connecting lines, the outputs of which are connected to the connecting lines of the oncoming PBX (in the inventive device - blocks with sets of connecting lines th analog, the outputs of which are connected to analog connecting lines), ISA control bus.

To increase the capacity of the DATS, N identical expansion modules (N from 1 to 7) are additionally connected to the control module.

To increase the capacity of the DATS, N identical expansion modules (N from 1 to 7) are additionally connected to the control module.

The drawing shows a structural diagram of the DATS "Proton-SSS", consisting of two modules: control module 1 and expansion module 18.

The control module 1 includes a control unit and switching BUK 2 (main), containing a processor module 3, signal processor modules (MSP) 4, tone generator 5, autoinformer 6, switch 7, clock generator 8, ISA 9 control bus. Switch 7, a tonal signal generator 5, an autoinformer 6, signal processor modules 4 are interconnected using intra-unit communications, and using in-station group paths via an ISA 9 bus, they are connected to a processor module 3 connected to the control computer. The modules of the signal processors 4 are connected to the switch 7 using in-plant group paths. In addition to BUK 2 (main) control module 1 contains blocks of system telephone sets of the control module (BSTA) 11, the outputs of which are connected to system telephones, a block of the operational search measures system (SORM) 12, the outputs of which are connected to the control panels of this system, a digital block interfaces (BIC) 13, the outputs of which are connected to digital synchronous serial interfaces and digital channels, blocks of digital line endings with pulse-code modulation (BTSO PCM) 14, the outputs of which are connected to external

Depending on the purpose of the station and consumer requests, the Proton-SSS TsATS may have various simplified layout options, for example, the absence of system telephone sets and / or operational search measures, etc.

1. Consider the work of the Proton-CCC DATS when establishing a connection between two subscribers of the DATC:

1.1 After subscriber A picks up the telephone of the terminal subscriber telephone device, the LHR 21 will receive the analog signal “Lift the handset”, which, after converting it to the LHC 21 into a digital code, will be received via the remote system bus 23, inside the RCI / BRIU station intermodule interfaces , RKZ / BRKZ (24, 17), system bus 10 into modules of signal processors 4, in which there will be a conversion of encoded signals with appropriate processing (filtering, etc.). From the output of the signal processor 4 through the bus ISA 9, the signal "off-hook" will go to the input of the processor module 3.

1.2 From the output of the processor module 3 through the ISA 9 bus, a command will be sent to the input of the tone generator 5 to issue a signal “Station response” to the switch 7. From the processor module 3 also

through ISA 9 bus from switch 7, a command will be sent to connect the “Station Response” signal to system bus 10. Through this system bus 10, through in-station intermodule interfaces RKZ / BRKZ, RCI / BRKI 17, 24, the signal “Station Response” will be sent to BAK 21 and from it to the terminal subscriber telephone device. The subscriber will hear the “Station Response” signal.

1.3 Subscriber A will dial the numbers of the called subscriber B on the terminal subscriber telephone device. The digits of the dialed number are converted in the LHC 21 into a sequence of encoded signals, which will be transmitted along the route described in Section 1.1 to the signal processor modules 4, where the encoded signals of the digits of the number will be converted with the appropriate processing (filtering, etc.) to processor module 3.

1.4 Depending on the digits of the number dialed by subscriber B, the processor module 3 through the ISA 9 bus will issue a command to the switch 7 for spatio-temporal switching between the channels of the calling A and the called B of the subscribers, then through the system bus 10, intra-station intermodule interfaces RKZ / BRKZ, RCT / BRC 17, 24, the LHC 21 of the called subscriber B will receive a command allowing the submission of the subscriber's call signal in the form of an alternating voltage generated by the ring voltage generator 22. The duration and period of the caller's signal are programmed in processor module 3.

1.5 At the same time, the caller A hears a call control signal (CPV) generated by the tone generator 5. This signal is transmitted from the tone generator 5 to the telephone terminal device similarly to the “Station Answer” signal (see clause 1.2).

1.6 If the dialed number is invalid, i.e. there is no subscriber with this number, a command to the autoinformer will be received from processor module 3

6 to issue the phrase “The number you dial does not exist” to the caller’s subscriber line A. The transmission of a signal with this phrase to the terminal subscriber telephone device is similar to the transmission of the “Station Response” signal (see clause 1.2). If the called subscriber B answers the phone call, then between the subscribers the “Subscriber response” mode is set. If one of the participants in the connection hangs up, then the connection is disconnected, which is monitored by the PBX hardware-software complex and the transition to the "Disconnect" mode occurs.

Similar to the process described above, the work of the Proton-CCC DATS occurs when establishing connections:

- from the caller to the caller inside the DATS for system telephones (BSTA 11, BSTA 19);

- through blocks with sets of analogue connecting lines to oncoming DSCS subscribers (BCSLA 20);

- through blocks of digital line endings with pulse-code modulation (BTsO IKM 14).

2. Consider the work of the Proton-CCC DATS when transmitting data from digital synchronous serial interfaces (BIC 13) or digital channels with a speed of 64 kbit / s between two DATCs through digital end-of-line units with pulse-code modulation 14 to similar digital synchronous serial Interfaces or digital channels at 64 kbps:

When configured by the operator, the TsATS program pre-sets the spatio-temporal switching between data channels corresponding to digital synchronous serial interfaces or digital channels with a transmission speed of 64 kbit / s and digital line channels with pulse-code modulation. In accordance with the software configuration

settings processor module 3 through the ISA 9 bus will issue a command to the switch 7 for spatio-temporal switching between these channels. Switch 7 will switch channels and data will be transmitted along the chain: data from digital serial synchronous interfaces or digital channels with a data transfer rate of 64 Kbps to the block of digital interfaces 13 through system bus 10 are sent to switch 7. In switch 7, data is transferred to the channel, corresponding to digital lines with pulse-code modulation and will go to the system bus 10 and then to the block of digital terminations of lines with PCM 14. At the oncoming Proton-CCC DATS, data will be transmitted in the reverse direction Sequences - from the block of digital line terminations with PCM 14 to digital synchronous serial interfaces or digital channels with a speed of 64 kbit / s.

"

3.3. If the subscriber number B received by the processor module 3 corresponds to the subscriber of the IP network, the processor module 3 transmits the subscriber number B to the IP gateway 16 along the route described in clause 3.1. If subscriber B is free (this state of subscriber B will be recorded by IP gateway 16 and will be transmitted in encoded form to processor module 3), calling subscriber A hears a call control signal generated by the tone generator 5. Generating and passing this signal It is performed similarly to the “Station response” signal (see clause 1.2).

3.4. If subscriber B picks up the phone, this action will be recorded by the IP gateway 16 and this event will be encoded to the processor module 3 via the signaling channel.

3.6. In switch 7, upon a command from processor module 3, spatio-temporal switching will occur between the caller’s channels and the channels corresponding to IP gateway 16, and compressed voice information in packet form will be transmitted via IP-network between subscribers A and B.

4.3. If the subscriber number B received by the processor module 3 corresponds to the terminal telephone subscriber device connected to the oncoming PBX, the processor module 3 transmits the subscriber number B to the CCM PCM 14 along the route described in Section 4.1. If the subscriber B is free (this signal of the subscriber B will be recorded by the CCM PCM 14 and transmitted in the encoded form to the processor module 3), the calling subscriber A will hear a call control signal (CPV) generated by the tone generator 5. Formation and passage this signal is performed similarly to the signal “Station response” (see clause 1.2).

4.4. If subscriber B picks up the phone, this action will be recorded by the CCM PCM 14 and this signal will be encoded into the processor module 3 via the signaling channel.

4.5. In the switch 7, upon the command from the processor module 3, a spatio-temporal switching will take place between the caller’s channel and the channel corresponding to the CCM PCM 14 and voice information will be transmitted through a digital connecting line between subscribers A and B.
