Description

The utility model relates to radio engineering and can be used to provide communications.

A number of examples of the implementation of internal communication and switching equipment (ABCS) are known, for example, switching equipment R-174T (tank switch), ABC "Zvezda", etc., which perform similar functions. Their disadvantages are: the lack of the possibility of arbitrary configuration of the communication system; a limited number of subscribers and channels of access to radio stations; large overall dimensions and unstable operation of the equipment due to outdated circuit solutions of the switching block of analog signals; lack of standard joints C1-PM, RS-232, Ethernet, which does not allow you to control modern radio stations and interfacing with data transmission equipment.

Closest to the technical nature of the proposed is the apparatus of internal communication, switching and control (ASCU) according to the patent of the Russian Federation 58834, adopted as a prototype.

The prototype equipment contains k micro-telephone headsets of subscribers (MTG), k blocks of pairing to them (BSMTG), k blocks of conversion (BPMTG); s telephone sets (TA), s interface units to them (BSTA), s conversion units (BITA); m radio stations (PC), m interface units to them (BSRS), m conversion units (BPRS); n APZD devices, n interface units to them (BSAPZD), n conversion blocks (BPAPZD); r devices having an Ethernet interface of IEEE 802.3 standard, an IEEE 802.3 standard Ethernet packet switching unit (BPC), and the input-output of each MTG through a series-connected corresponding BSMTG and BPMTG connected to the corresponding of the k input-outputs of the first group of input-output BKP, input - the output of each SLA through the correspondingly connected BSTA and BSTA is connected in series with the corresponding of s inputs and outputs of the second group of I / O of the BKP, the first, second, third outputs and inputs of each PC are connected with the corresponding inputs and outputs its BSSR, the fourth output-input of which through the corresponding BPRS is connected to the corresponding of m inputs-outputs of the third group of inputs and outputs of the BKP, the input-output of each APZD through series-connected corresponding BSAPD and BAPAPD is connected to the corresponding of the n inputs-outputs of the fourth group of inputs - BKP outputs, the output-input of each device having an Ethernet interface of the NEE 802.3 standard is connected to the corresponding of the r inputs and outputs of the Nth group of I / O of the BKP.

Equipment prototype works as follows.

To enter the communication or control mode, the subscriber dials the address of the called subscriber or device on the keyboard of his individual BPMTG, the operating mode and establishes a connection.

An analog speech signal from any of the MTGs is sent to the appropriate BSMTG interface unit, where the signal levels are matched, and then to the corresponding BPMTG, where the signal is sampled at a frequency of eight thousand samples per second, which, when the bit resolution is 16 bits, leads to the information speed of the speech signal 128 Kbps An operation mode in which the digitized signal is converted according to the A-low (-low) law into samples with a bit capacity of 8 bits can be implemented in the ASCU as well, while the information rate is 64 Kbps. Further, the digital stream is divided into Ethernet interface packets in accordance, for example, with the IEEE 802.3 standard, each of which together with the information bits contains the address of the called party, the type of information (in this case, the speech signal) and the address of the calling subscriber. Packed information is sent to the BKP, which is a necessary set of hubs connected together by two twisted pairs (HUB), and after passing the established route, it is fed to the called subscriber’s conversion unit, SLT, radio station, ADF or to a device that has an IEEE 802.3 Ethernet interface.

Digital information from the radio station arrives, for example, at the junctions С1-ФЛ, С2 or С1-ТГ through the BSSS to the BPRS, it is divided into packets in accordance with the IEEE 802.3 standard, each of which together with the information bits contains the address of the device for which the information is intended, type of information (in this case, digital information received at the junction of C1-FL, C2 or C1-TG) and the address of the transmitting device. Packed information is sent to the BKP packet switching unit and, after passing through the established route, it is fed to the conversion unit of the receiving device or directly at the Ethernet interface to the corresponding devices.

Digital information received at the joints of C1-FL or C1-TG from the APZD is delivered to the recipient device in the same way.

Digital information transmitted from the devices at the Ethernet interface is fed to the switching unit of the BKP and then to the conversion unit of the recipient device, where it is unpacked and in the required format through the appropriate interface unit is transmitted to the receiving information device.

The disadvantages of the equipment of the prototype are: the lack of the possibility of arbitrary configuration of the communication system; a limited number of subscribers and channels of access to radio stations; large overall dimensions and unstable operation of the equipment due to outdated circuit solutions of the switching block of analog signals; the lack of standard joints C1-TCH, RS-232, Ethernet, which does not allow you to control modern radio stations and interfacing with data transmission equipment.
