The invention relates to the field of wireless communications and is intended to work as part of radio relay equipment when organizing zone and local communication lines, radio access in the field.

Known access module (patent No. 75815, publ. 20.08.2008), including a multiplexing unit, a generator unit, an Ethernet interface unit, an Ethernet packet switch, interfacing units with transceiver devices and a main channel unit made in the form of interface terminations.

This access module does not implement the ability to receive information over the STM-1 interface. There is no adaptive mode in order to decrease or increase the transmitter power at the other end of the radio link based on the analysis of information about the quality of the input signal. The control functions of the access module do not provide for the registration of events taking into account the time of their occurrence in order to control and obtain objective information about the state of the module and the station as a whole.

Known access module (patent No. 70433, publ. 20.01.2008), taken as a prototype, including a built-in multiplexer and made in the form of replaceable units: multiplexing unit, interface unit of the main channel, made in the form of a channel interface 16x E1 or E2 or E3 , Ethernet interface node, additional channel interface node, power supply unit, interfacing units with transceiver devices, generator unit, service communication unit made in the form of a two-wire termination interface.

The prototype does not implement the ability to receive information over the STM-1 interface, nor does it provide an adaptive mode in order to reduce or increase the transmitter power at the other end of the radio link. The control functions do not provide for the registration of events taking into account the time of their occurrence in order to control and obtain objective information about the state of the module and the station as a whole.

The technical result of the invention is to expand the arsenal of technical means for the specified purpose with additional functionality, expressed by the introduction of an operation mode for transmitting / receiving traffic over the STM-1 interface, implementing an adaptive mode for adjusting the transmitter power at the other end of the radio link, ensuring the registration of events taking into account the current time at the moment their occurrence.

The specified technical result is achieved by the fact that the access module consists of a multiplexer, a power supply unit, a switching board and a monitoring and control module. The multiplexer and the monitoring and control module have a first bidirectional CAN bus communication and a second bidirectional serial bus communication. The first and second outputs of the power supply are made in the form of connectors for connecting the power cables of the transceiver devices, the third and fourth outputs of the power supply are connected, respectively, to the input of the multiplexer and to the input of the monitoring and control module. The multiplexer is bilaterally connected to the switching board, contains connection connectors for receiving / transmitting over the STM-1 interface, over the Ethernet interface, and the switching board contains connection connectors for receiving / transmitting information over the E1 channel. The monitoring and control module includes a processor that is bi-directionally connected to the control board, an Ethernet transceiver, a CAN transceiver, an RS-232 transceiver, a random access memory (RAM), a read-only memory (ROM), and a real-time clock module. The control board contains inputs / outputs for receiving / transmitting via the Ethernet interface and via the service communication channel. The Ethernet transceiver contains an input-output connection to an automatic operator's workstation (ARMO).

The invention is illustrated in the drawings, where FIG. 1 shows a functional diagram of an access module; FIG. 2 is a functional diagram of a monitoring and control module.

The access module (Fig. 1) consists of a control and management module 1, a multiplexer 2, a power supply 3, a switching board 4. The control and management module 1 (Fig. 2) includes a control board 5, a processor 6, ROM 7, RAM 8, real time clock module 9, Ethernet transceiver 10, CAN transceiver 11, RS-232 transceiver 12.

The control and management module 1 controls the multiplexer 2 via the CAN bus, saves the configuration in ROM 7 and restores it after turning on the power through RAM 8. When working with the multiplexer 2, it generates a service group signal (GDS), consisting of the following channels: telecontrol-telesignalization (TU -TS), service communication (KCC) and an additional Ethernet channel, provides the implementation of adaptive modes for adjusting the transmitter power at the other end of the radio line, maintains a protocol for registering events with a record of the time of their occurrence, provides sound signaling of the KCC call and light signaling of the state of the radio relay equipment components.

Multiplexer 2 works with two independent groups of user interfaces operating on two transceiver devices, and provides reception and transmission of subscriber traffic over the E1 channel, Ethernet, STM-1 interfaces, as well as TU-TC and KSS channels from the monitoring and control module 1.

The power supply unit 3 provides the monitoring and control module 1, the multiplexer 2 with a stabilized voltage + 5V, and two transceiver devices with a voltage from -39 to -72 V.

Switching board 4 provides a transition from one type of cable to another, which allows, without changing the configuration of the access module, to change the configuration of external joints.

The access module works as follows. After applying the supply voltage to the input of the unit

- 1 037163 power supply 3, a stabilized voltage appears at the output, which is fed to the monitoring and control module 1 and the multiplexer 2. The voltage is supplied to the transceiver devices connected to the access module through the connectors for connecting the power cables of the transceiver devices. The control commands are sent to the processor of the monitoring and control module 1 with ARMO through the Ethernet 10 transceiver. The processor 6 processes them and transmits the commands through the CAN 11 transceiver, where the signal is converted into the CAN standard, to the multiplexer 2. Information on the results of the control commands from the multiplexer 2 to the CAN bus is fed to the processor 6 of the monitoring and control module 1 and through the Ethernet transceiver 10 to the ARMO.

The control board 5 from the subscriber receives an analog signal via KCC and a digital signal from an additional Ethernet channel, as well as from ARMO through an Ethernet 10 transceiver formed in the processor 6 channel TU-TC. The control board 5 generates a service group signal (GDS) and transmits it via the serial bus to the multiplexer 2. The processor of the multiplexer 2 also receives the main information streams from each of the two groups of user interfaces operating independently of each other, according to one of the established operating modes: mode Ethernet - Ethernet traffic arrives over the Ethernet junction, E1 + Ethernet mode is the E1 channel at the E1 junction and in the remaining free Ethernet channel slots traffic is sent over the Ethernet junction, STM-1 mode is STM-1 traffic at the STM-1 junction. In the processor of the multiplexer 2, two multicast streams are formed from the service group signal and the main information streams, which are transmitted via Ethernet 1000 BASE-X channels to two independent transceiver devices.

The multicast streams received from the transceiver devices via Ethernet 1000 BASE-X channels are fed to the multiplexer 2, where they are divided into GDS and information streams. Each information stream, in turn, depending on the operating mode Ethernet, E1 + Ethernet, STM-1 is divided in multiplexer 2 into E1, Ethernet, STM-1 channels, which are distributed to the subscriber via one of the two groups of user interfaces. GDS comes from multiplexer 2 to control board 5 via a serial bus, where an additional Ethernet and KCC channel are allocated, and are transmitted to subscribers. The TU-TC channel from the control board 5 goes to the processor 6 and through the Ethernet 10 transceiver to the ARMO. Occurring events (actions) are recorded in the processor 6 by writing to a file, which also records the time of occurrence of the event coming from the real-time clock module 9. If necessary, the operator with the ARMO, using the appropriate commands, requests a list of events indicating the time of their occurrence. The program code is located in ROM 7, when turned on, the program is copied to RAM 8 and launched for execution.

During the operation of the access module, the processor 6 of the monitoring and control module 1 controls the quality of the incoming signal at the receiver of the station's transceiver device. In the case of high / low quality of the incoming signal, the processor 6 generates and sends a command through the TC-TC channel to decrease / increase the transmitter power at the other end of the radio link, thereby realizing the adaptive mode. When setting up or repairing an access module, testing commands for operability are sent to processor 6 through the RS-232 12 transceiver, where the signal is converted to the RS-232 standard, the information generated in the processor 6 for the corresponding test commands is sent to the RS-232 transceiver 12, signaling the status access module.
