Abstract

PURPOSE:To attain confirmation of operation without using a trunk line relay board by acquiring an outgoing trunk with a specific number for trunk designation acquisition from an extension subscriber and dialing of a trunk designation number. CONSTITUTION:When the extension subscriber dials a specific number for trunk designation acquisition by an extension telephone set STA, a central controller 4b detects the information and discriminates it as trunk designation acquisition by using specific number information stored in a storage device 5b. Moreover, when the extension subscriber dials a trunk designation number, the central controller 4b discriminates allocated position information of an outgoing trunk 3 corresponding to the trunk designation number stored in the storage device 5b to close a channel swithc 2 between the outgoing trunk 3 and the extension subscriber telephone set STA.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a trunk designated acquisition system in a storage program controlled switch.

[Prior art]

Conventionally, in this type of trunk designation acquisition method, as shown in FIG.
) 4a is detected and determined to be a transfer designated acquisition. Thereafter, when the designated number of the outgoing tran # (TRK) 8 to be captured is dialed from the central office relay stand (ATT) 1, the central control table N4a is stored in advance in the storage section M (Mt
) 5a The outgoing trunk corresponding to the trunk designation number dialed from the information stored in a (!1” RIo
8 accommodation location information is classified, and the outgoing trunk (TRK
) 8 and the central office line relay stand (ATT) 1 (8)
W) 2 was closed.

Therefore, in the conventional system, when a maintenance person checks the operation of an outgoing trunk, a central office line relay stand is used, so it cannot be used when an operator is using it, and there is a restriction on the time period for checking the operation.

〔the purpose〕

An object of the present invention is to eliminate the drawbacks of the above-mentioned conventional example and to confirm the operation of the outgoing trunk by capturing the outgoing trunk by dialing a specific number for capturing the trunk designation from the extension subscriber and the trunk designation number. The goal is to do this easily and efficiently.

[Structure of the invention]

In order to achieve the above object, the present invention provides, in an exchange using a storage program control system, a specific number for specifying and capturing an outgoing trunk, and a storage position corresponding to the trunk designation number of the outgoing trunk, in a storage section of the exchange. The central control unit is equipped with a function to receive the specific number and trunk designation number and capture the outgoing trunk, and the extension subscriber dials the specific number and trunk designation number to capture the outgoing trunk. It is characterized by specified capture.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. Second
The figure also shows a block diagram of the trunk designated acquisition method according to the present invention, and the storage unit (M2) 6b has storage corresponding to a specific number for trunk designated acquisition and the trunk designated number of the originating trunk (TRK) 8. Location information is stored, and the central control unit (00z) 4b is equipped with a function to identify the above-mentioned specific number and trunk designated number. Furthermore, the second
In the figures, elements having the same functions as those in FIG. 1 are given the same reference numerals.

To explain the operation of the above embodiment, when an extension subscriber (not shown) dials a specific number for acquiring trunk designation using an extension telephone STA, this dial information is sent to the central controller 4.
Based on the specific number information detected by the controller ff5b and stored in the storage device ff5b, it is determined that the trunk-designated acquisition has occurred. Thereafter, when the extension subscriber dials the trunk designation number, the central controller 4b identifies the storage location information of the outgoing trunk 8 corresponding to the trunk designation number stored in the storage device 5b, and connects the outgoing trunk 8 and the extension subscriber. Close the communication path switch 2 between the telephones STA.

〔effect〕

As explained above, according to the present invention, it is possible to acquire a trunk specification by dialing a specific number and a trunk specification number from an extension subscriber, and it is possible to easily and efficiently check the operation of the outgoing trunk. effective.
