Description

The invention relates to communication technology and can be used in coordinate automatic telephone exchanges (ATC).

The purpose of the invention is to simplify the device.

An outgoing call establishment device in an automatic telephone exchange includes an additional services unit T, which is connected by first inputs / outputs 2 to a first input / output unit 3 connected via a system bus 4 to a control unit 5 common to the group of units 1,

The group of subscriber sets 6 is connected via a subscriber search unit 7 with AB links to the inputs of the outgoing cord set 8 (ISC), the outputs 9 of which are connected to the input of the first stage of the group search unit 10. The outputs 11 of the ISK 8 are connected to the input of the register search block 12. The subscriber register 13 is connected by a busy wire 14 to the first input 15 of a busy marker 16 code receivers. The output of the marker 16 is connected to the input 17 of the occupied unit 18 of the code receivers, which consists of the relay node 19 (RPA) and the electronic node 20 (KP).

The subscriber search unit 7 contains a marker 21 of links AB, which includes determining the numbers of the calling subscriber (not shown). The group search block 10 comprises a group search marker 22 (GI marker). The register search block 13 comprises a register search marker 23.

The device includes, in addition, an information transmitting / receiving unit 24, a generator 25, a second input / output unit 26 and a third input / output unit 27.

ABOUT

Block 1 of additional services is connected by the second inputs-outputs 28 to the output of the register search block 12, by the third inputs-outputs 29 to the subscriber register, and by the fourth inputs-outputs 30 to the first inputs-outputs 31 of the information reception and transmission block 24.

The information reception and transmission unit 24 is connected by its second inputs / outputs 32 through the second input / output unit 26 to the system bus 4, and by the third inputs / outputs 33 to the code receiver unit 18.

The output 34 of the occupied unit 24 is connected to the second input 35 of the occupied marker 16 code receivers.

The frequency inputs 36 of the block 24 of the reception and transmission of information are connected to the outputs 37 of the generator 25.

Determine the caller numbers of the token 21 AB on the bus 38 through the third block 27 I / O connected to the system bus.

Let us consider the principle of operation of an outgoing call establishment device in a coordinate exchange.

Suppose that a subscription has ordered an additional service reduced dialing.

When the subscriber picks up the handset, the call signal through the subscriber complex 6 enters the marker 21 of the links A8 of the subscriber search unit 7. In marker 21, the identification of the number of the caller. Then, the free outgoing cord set 8 is taken, the number of which corresponds to the combination of test relays (not shown) of the marker 21. On the 3S bus, through the third I / O block 27, the recognized caller number and the number of the outgoing cord complex 8 {ISHC} are received through the system bus 4 to control unit 5,.

After occupying HIC 8 through block 12 of the registry search with marker 23, it takes block 1 of additional services and associated subscriber register 13, and this busy signal from block 1 is transmitted indicating the number of HIC 8 through the first block 3 I / O to the block 5 controls and fix it in it.

In the control unit 5, the number of the calling subscriber connected to this CSI is determined by the number of the HIS 8, and the type of additional service that this subscriber has ordered is determined by the number of the calling subscriber. In this example, this is abbreviated dialing. - At the command of the control unit 5, from the unit 1, the ready buzzer is sent to the caller - a response signal of a supplementary services system limited in duration. The abbreviated dialing numbers to be dialed are received in the control unit 1, where the full number of the called subscriber is determined from the digits of the abbreviated number.

After that, from the control unit 5, through the second input / output unit 26, the information reception and transmission unit 24 is occupied and a command is transmitted to it to occupy the marker 16 of the code receiver unit 18.

Digital information is provided in a frequency manner necessary for establishing a connection at the request of search stage markers, starting with the request of marker 22, according to commands from control unit 5 through blocks 18 and 24 connected to multi-frequency generator 25.

After issuing from the control unit 5 the last digit of the full number of the calling subscriber, it receives the connection end signal transmitted from the subscriber search unit marker (not shown) of the subscriber search unit 7, the confirmation response signal is transmitted, and the process of establishing outgoing connection. In this case, the additional services unit 1 and the associated nodes and units are returned to the initial state by the commands of the control unit 5.

If, after the end of the transmission of the response signal of the supplementary services system for the specified subscriber for a predetermined time, there is no dialing, or if the calling subscriber ordered the Outgoing service with a password, and in the control unit 5, the digits of the number received from 0 subscriber coincided with ordering the service with a password in numbers, from the control unit 5, through the first I / O unit 3 to the additional services unit 1, a command is sent to connect the subscriber regi-5 page 13 to the register claim block 12. In this case, the calling subscriber receives the second readiness buzzer from the outgoing cord set 8, and the digits of the called number and the subsequent establishment of the outgoing connection are received using the subscriber register 13, and all this happens in the same way as in the known Automatic telephone exchange.

The difference between the implementation of the additional service Establishing a connection without dialing a number from the considered connection consists in the fact that after determining in the control unit 5 the type of registered customer, the number of which has arrived

from the service marker 21, the reception operations in the control unit 5 of digits for abbreviated dialing are not performed, and the full number of the called subscriber is determined by the number of the calling subscriber.

If it was found by the caller’s number in the control unit 5 that the Outgoing call barring service was ordered by this subscriber, or if the numbers dialed by the subscriber do not match the password for the Outgoing call service from the block 5 through the first block 3 I / O, additional services unit 1 and register search stage 12 send the corresponding disconnect command to the outgoing cord set 8, and instead of the ready buzzer, the Zanto buzzer is transmitted to the caller.
