 In FIG. 1 shows a structural diagram of the proposed device for the provision of Intelligent network services; in FIG. 2 algorithm of the computer, which is part of the proposed device; in FIG. 3 example of the implementation of a circuit of a frequency receiver; in FIG. 4 is an example implementation of a master oscillator and frequency driver circuit; in FIG. 5 is an example implementation of an interface controller circuit; in FIG. 6 is an example implementation of a message driver circuit.

 The device for the provision of services of the Intelligent network (Fig. 1) contains: "n" incoming communication lines 1, switching field 2, "n" outgoing communication lines 3, "n" incoming input couplers (BSVs) 4, consisting of an occupation unit 5 and information receiving and transmitting unit 6, “n” outgoing interface units (BSI) 7, consisting of an occupying unit for the outgoing communication line 8 and a signal receiving unit from the called subscriber 9, “n” message formers (FS) 10, “n” frequency drivers (FC) 11, "n" multi-frequency receivers (MP) 12, the master oscillator (CG) 13, the controller interface (KI) 14, the controller bus (CC) 15 and the computer 16.

 A device for providing services of the Intelligent network operates as follows.

 When a request arises for the service of the Intelligent network via the incoming communication line 1, the signal “Occupation” is received in the input unit 4, intended for matching control signals and interaction between the equipment of the Intelligent network and the equipment of existing switching stations.

 Occupation unit 5 of the incoming 4 interface unit monitors this signal and in a converted form provides the Occupation signal via controller bus 15 to interface controller 14.

 The interface controller 14 is designed to control the interface blocks outgoing and incoming, the switching field and interaction with the computer in the process of servicing applications for establishing connections with subscribers of the Intelligent network. In addition, its functions include the control of the FS, FS, as well as the reception and processing of encoded signals from the MP.

 At the command of the interface controller 14, which is received via the controller bus 15, the information reception and transmission unit 6 of the incoming 4 interface unit issues an “Number request” signal on the incoming communication line 1 to the station side.

 Information about the number is transmitted in a decade-wise way on the incoming communication line 1, is converted into a BSV 4 information receiving and transmitting unit 6, and is supplied to KI 14 via HQ 15.

 Upon completion of reception of the Ki 14 number through the HQ 15, it issues to the information receiving and transmitting unit 6 BSV 4 a command for issuing the “Subscriber is free” signal on the incoming communication line 1.

 At the same time, KI 14 transmits via SHK 15 a command in a switching field 2 for connecting a shaper of messages 10 and a start command in a shaper of messages 10, which will initiate the issuance of advertising or some additional information for the calling subscriber at the time of recounting the received logical number of the called subscriber and establishing a connection to it for call forwarding services).

 The previously adopted number KI 14 transmits to the computer 16.

 In the computer 16, the number is processed in accordance with the algorithm (Fig. 2).

 In the initial state, the computer 16 expects an application from KI 14. Upon receipt of a service request from Ki 14, the computer 16 analyzes the service code, namely, the search and generation of control information necessary for the implementation of the service.

 At the end of processing, the computer 16 transmits to KI 14 a command to complete the process of establishing a connection and the necessary control information, in particular, it can be the physical number of the called subscriber, and proceeds to the tasks of billing the service, collecting statistics, and awaits a new application from the KI.

 KI 14 transmits the “Occupation” command through HQ 15 to the occupation unit and the outgoing line 8 of BSI 7, which is designed to give the “Occupation” signal to the station along the outgoing line 3 at the Ki 14 command.

 At the same time, KI 14 through ShK 15 sends commands to the switching field 2 to connect the frequency former 11 and the multi-frequency receiver 12 to the outgoing communication line 3.

 The signal "Request information" from the station enters the outgoing communication line 3 through the switching field 2 to the multi-frequency receiver 12.

 Multi-frequency receivers 12 are designed to convert control signals received on outgoing communication lines with the multi-frequency code "2 of 6" into the position code "2 of 6" TTL level.

 The converted signal after the multi-frequency receiver 1 enters through the HF 15 to KI 14. In response to the "Request for information" by the command KI 14 issued through the HK 15, the frequency driver 11 transmits control information through the switching field 2 over the outgoing communication line 3 in the form of a pulse packet code "2 of 6".

 The receipt of the "Response of the called subscriber" on the outgoing communication line 3 is monitored by the block receiving signals from the called subscriber 9 BSI 7.

 The block receiving signals from the called subscriber 9 is designed to receive signals "End" and "Answer the called subscriber" and transmit them in converted form to KI 14.

 KI 14, after receiving the signal "Response of the called subscriber", through the CC 15 issues a command to the switching field 2 to turn off the message former 10 and the conversation path between the called and calling subscribers.

 At the end of the conversation, “Hang up” can come from both the caller and the called party.

 “Hang up” by the called party.

 The “End call” signal is received via the outgoing communication line 3, monitored by the signal receiving unit from the called subscriber 9 BSI 7, converted and transmitted through the HQ 15 to the CI 14. Upon the command of the CI 14 received by the HQ 15, the BSI 7 occupation unit 8 picks up the signal Occupation "issued on the outgoing communication line 3, and the switching field 2 disconnects the talk wires.

 At the same time, KI 14 transmits the “End” signal through the CC 15 to the information receiving and transmitting unit 6 of BSV 4, where it is converted and issued via the incoming communication line 1 to the control device of the switching station, and the message “End” of the computer 16.

 When you remove the signal "Occupation" on the incoming communication line 1 unit occupation 5 BSV 4 goes into its original state.

 Hang up from the calling party is handled similarly to hang up from the called party.

 Such an embodiment of the device, in which due to the introduction of new units, namely, interfacing blocks for outgoing KI, computer, frequency converter, MP, HK, ZG, it is possible to connect any subscriber or device on the network to the caller, it allows providing a variety of Intelligent network services to subscribers.

 Switching field 2 is intended for connecting to the outgoing and incoming communication lines of the necessary devices and units (FS, FS, MP), as well as for the termination of conversational wires.
