Abstract

The invention relates to long-distance telephone communication. The purpose of the invention is to simplify the device. The device contains a long-distance pay phone 1, subscriber line 2, automatic telephone station 3, on which a matching set 4 is installed, subscriber set 5 with node 6 for automatically determining the number, charging pulse generator 7, node 8 for receiving and fixing charging signals and steps 9 and W iskanii, as well as a custom trunk line 11 and an automatic long-distance telephone station 12 with control of a recorded program and with the equipment 13 tariffing. The goal is achieved by simplifying the electronic part of the set-top box, eliminating the need for rewiring in a long-distance telephone, as well as additional switching and recoding associated with a change in the tariff for a given location. 1 Ю1.

Description

00 N5

The invention relates to intergo. native telephone communication and can be used in organizing the area telecommunication of the automatic telephone exchange with control according to a given program.

The purpose of the invention is to simplify the device.

The drawing shows a block diagram of the proposed device to connect 10 m long-distance public telephone booths (MTA) to an automatic long-distance telephone exchange (AMTS) controlled by a recorded program.

The scheme contains MTA 1, subscriber 15 line 2 (AL), PBX 3, which has a matching A-link (CK), subscriber set 5 (AK) with a node: 6 automatic number identification (ANI) 6, generator 7 tariff- 20 ; pulses, node 8 receiving and; fixing the charging signals of steps I and 9 and 10 of the search, custom-connecting I line 11 (ZSL) to AMTS 12 with I control according to the recorded program 25

and tariffication equipment 13 (OT). ; The device works as follows. ZOM.

: When picking up the tube C, MTA 1 is occupied by SC 4, which in its turn ZO is occupied by AK 5. The subscriber has the signal

: station readiness from the PBX equipment 3. After dialing the number 8, a connection is established to the free ZSL 11, going to the AMTS 12. At the AMTS 35 is connected FROM 13, into which you turn on to the ZSL 11 and the ATN 3 is sent to the ATC 3 . From the node 6 AON in the direction of the AMTS station 12 12, information is given containing the subscriber number and category of the subscriber unit (number 6). After analyzing the category of the subscriber number in the central processor of the automatic long-distance telephone station and from 13, the long-distance telephone station will issue a readiness signal. The Nabi-45 subscriber has a long-distance number (ABC avs xxxxxx), then, after 200 ms, the billing equipment sends a signal about the number of the tariff zone to the PBX 3 by the multi-frequency cathode. This Q signal is received by the receiving and fixing unit of the tariff zone number

ATC 3 and controls the generator 7 of the charging pulses of the electronic part of the IC 4. From the output of the generator 7 of the charging pulses through the IC 4 and AL 2, MTA 1 receives the charging pulses that follow the frequency of the required rating zone.

The proposed device uses standard blocks applied at all existing long-distance telephone exchanges.

The technical and economic efficiency of the proposed device in comparison with the known one is to simplify and reduce the cost of the proposed device by simplifying the electronic part of the set-top box, eliminating the need for remounting in the MTA, as well as additional switchings and recodings associated with a change in tariff for a given area.
