JPS5923697A - Main wire imcoming call transferring system - Google Patents

Abstract

PURPOSE:To eliminate delay of a connection and a non-connection to an objective subscriber by connecting a main wire call to a talkie equipment according to a set condition at the time of main wire receiving, and transferring receiving to a specified device by the equipment. CONSTITUTION:When an ATT operator of a main wire B board depresses a specified ATT button, it is informed to a controlling device CC, and CC stores the information of a button depressing in a memory MM. CC detects an incoming to a main wire trunk CIT, and refers to the MM for presence of ATT specified button depressing and checks. When the information of button depressing is stored in the MM, CC makes a main wire reply, and connects CIT to a code receiver CDREC through a channel NW and starts CDREC. On receiving a starting signal, CDREC becomes PB code receiving state, and receives PB code from CIT. A received code is informed to the CC, and the CC analyzes the code, and connects to a relevant SUB through NW. By this way, the main wire incoming call can be connected to an extension without a long delay even when the number of operators is small or absent.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a central office line termination connection system in a private branch exchange.

(2) Conventional technology and problems Conventionally, when connecting to a central office line, there are two methods for connecting incoming calls: one is a system in which the operator manually connects to a specific extension after the operator answers the incoming call, and the other is automatic guidance when the operator is not available, such as at night. There is an alternative method in this case that involves connection to the caller, but the former has the disadvantage that the response to the call is slow and the caller cannot connect to the intended called party or device.

(3) Object of the Invention The object e of the present invention is to realize a means that makes it possible to eliminate connection delays and non-connection fees for target subscribers in connection with the latter type of automatic switching system.

(4) 11 Constituents of the Invention The present invention provides a 1-G device which has a private branch exchange with an announcement function and a PS code, digital code, voice subject 4+l'I code reception function, which can be operated by the operator or automatically. ni l
Incoming calls to the Geda line, more than a certain number of l:ty answering calls, a certain amount of time being taken -] 6 stuck unanswered calls, etc. Automatically answer incoming calls to the central office line, 99 transmitted by the caller, the caller will be able to connect to the terminal or device (among other purposes), and will be able to connect to the device or J9 by shortening the connection time. ．． This aims to reduce operator costs by reducing the burden on operators.

(5. Embodiment of the Invention As an embodiment of the present invention, a central office line incoming call connection system in which an incoming call to a specific central office line is automatically answered after the attendant presses a button and is connected to an extension line will be explained using drawings. ..

In the figure, CIT is a specific office line trunk, ATT is a office line relay stand, 0DR1nO is a code receiver, F117B is an extension, NW is a communication path, and SPC! is a communication path/trunk drive monitoring device, CC is a control device, and MM is a memory.

When the ATT operator presses the ATT specific button, SPC! aC (C will be notified via SPC, and CC will store the button press information in M M. CC will detect the incoming call to O and T via SPC, and A'
Check whether the T T specific button has been pressed by referring to MMi. If the button press information is stored in MM, Oa issues a command to OIT via SPC and responds to the central office line, and also connects to 0DRKO via the path indicated by ■ in NW, and 0D.
Spend startup money on RKO. When the CDREC receives the activation signal, it announces it to the CIT, enters the PB code reception state, and receives the FB code from the CIT (The received code is notified to the Co via the SPO). Connect to the corresponding 811B. When a call arrives at the CIT, if the specific button information of MM[ATi' is not stored, turn as before and send it to the ATT. Note that the figure is part of the present invention #1 This is merely an example, and all kinds of automatic switching conditions, condition setting means, and connection settings can be set for incoming calls on the central office line.

For example, t;j: If ATT is the only means of setting the condition, input command 7 from the quiwriter, l+'.
,? Dialing from a fixed extension line is not possible, and the automatic switching conditions are not only for incoming calls to a specific line but also for more than a certain number of calls.
K answering call, there is also an incoming 1h call that has been active for more than a certain period of time, and as a connection issue, IJ and CJH are connected to C, and the code is ready ffl transfer connection, C1) REC Kinkai Sasu j1
There are 4+ii methods of connection to a contact terminal, etc., but the effect of the present invention remains the same even for IL etc. (6) Embodiments of the invention According to the present invention, the number of users is small. In addition, 1-J, even if the user is absent, an incoming call from the central office line can be connected to the target extension line without being held for a long time, thereby improving serviceability and reducing costs.

[Brief explanation of drawings]

The figure shows a central office line incoming call transfer system according to an embodiment of the present invention.CIT: central office trunk ATT: central office relay stand CDREC: code receiver s + r B: extension subscriber NW: speech path spa: Communication path connection, device 4 monitoring device CC: control device

Claims (1)

[Claims] A private branch exchange having a function to connect an incoming call to a central office line is provided with a preset setting means for connecting the central office line to a talkie device having an announcement function and various code receiving functions, and a means for receiving a specific code after a central office line response. , when a call arrives from the central office line, the incoming call from the central office line is connected to the talkie device according to the conditions set by the connection condition setting means, and the same device receives the code from the central office line, thereby transmitting the call to the specific device. A central office line incoming call transfer system that transfers incoming calls.
