The invention relates to telecommunications. A device for switching discrete messages is known, which contains a memory block g whose information output is connected via a decoder to the control inputs of the output channel blocks, to information inputs of which the information outputs of the input channel blocks are connected via information bus, the control outputs of which are connected to the read input via the information bus the memory unit, to the control input of KbiopotO, the output of the control unit is connected to l & 1. However, the limestone of the Gustgosoyshao rummer is the purpose of the invention. bushes by listening to the reception of 6 sensors of signals Call and from input and output kangal. (5IRC. For this purpose, a device for coiutating discrete messages containing a storage unit, the information output of which is connected via a decoder to the control inputs channel blocks, to the information inputs of which, via the information bus Cdc, the information outputs of the input channel blocks, whose control outputs are connected via an encoder to the readout platoon of the memory block, to To the right input of which the output of the control unit is connected, a register block, a phase counter and a clock interval counter are entered, the corresponding outputs of which are connected to the input of the FA counter and to the control input of the register block, whose information input is connected to the information bus, the information output is connected to vhbdu control unit, and the input. And the number of the clock interval and the input and output of the array of information - connected to the corresponding inputs and outputs of the haM; A memory block, the output of the HBm phase of which is connected to the input of the Chyka..tactual intervals, and the output of the .1 phase is connected to the input of the Number of the storage unit. The drawing shows a structural electrical circuit of the proposed device. The device for switching discrete messages contains a storage unit 1, the information output of which is connected through the decoder 2 to the control inputs of the output channel blocks 3, to the information inputs of which through the information bus .4 the information outputs of the input channel blocks 5 are connected, the control outputs of which through the encoder 6 connected to the read input of the storage unit 1 to the control input of which the output of the control unit 7, the register unit 8, the phase counter E and the counter 10 clock intervals, is tvetstvuyuschie outputs of which are connected to the input of the phase counter 9 and to a control input of the register 8, an information input of which is connected to the data line 4, data output connected to an input of the control unit 7 as well. input and output The number of the clock interval and the input and output, the array of information is connected by b corresponding inputs and output 6 da of the storage unit 1, the output of which phase number is connected to the input of the counter of the clock intervals 10, and the output of the phase counter 9 is connected to the input The phase number of the storage unit 1. The device operates as follows. The voltage drop of the signal that occurs in one of the input channel blocks 5 through; the encoder b reads the control word from the address of the incident output channel block from the storage unit; - the number of the cycle, in which the previous differential signal occurred, - the array of information, for example, one byte; The phase numbers of the clock counter, which is currently being referred to for a new clock number. The address of the output channel block 3 with the help of a dyfr a: d1r a 2 changes the polarity of the output of the yyr-infb avd in, corresponding to yyyyyyyyyyyyy. Previous issue: T; a; kta; i-mass information is recorded. p., jjei HcT-: ditch 8, and the phase number; The access control counter input .10, the measure number, containing 1 | s in the test control word, and the current iHortiei measure received by the registrar module from the output of the counter 10, are used to determine the number of clock intervals that have passed, not the previous one: pada pada from persecution to the drepadha is encompassing: this is real. The number of ticks j tSH-p thus determined is the number of identical information 1e ems ntov; prisoners between the last two signal drops. The absolute value of the information elements (O or 1) is determined by the last element recorded in memory in block 1. The information array is supplemented by information found and information elements. In this case, the lely information register, which is part of the register block 8, is completely filled, its contents are dumped into the control block 7, and the / information elements are written into the empty register. At the end of the recording of all the previous elements, the last element is recorded in the register, which corresponds to the differential of the signal processed at the moment. For auto-tuning, counter 10 has several phases. The clock interval is divided into K smaller time intervals - phases. The change of the number of the cycle does not occur simultaneously on all phases, - and first only on the first, then on the second, third, etc., up to the K -th phase, inclusive. Each cycle repeats this cycle again. Consequently, at any moment in time it is possible to find a phase that is sufficiently far from. the phase in which the number of the cycle is changed in data 1: ... the phase number, corresponding, for example, to the middle of the clock interval, is determined by the phase counter 9 during the processing of this differential by counting the number of phases whose state has changed since the last measure until the control word is read. The phase counter generates a phase number that corresponds to the middle of the clock interval, and writes it to the storage unit 1. Thus, the switched pulse signals are accumulated in the storage unit 1 and transmitted to the control unit ck bk; Ti. ) OU block 7 10t: s Й K f /; f ya 1 I Otfic each from ,, JcQ are in the mode ;; Usgand19Yen11Oh; compounds.
