Abstract

PURPOSE:To set for a calling from a private line and an extension without limiting a held calling to an incoming from a trunk line and efficiently service the calling transfer by providing a holding terminal memory every subscriber in a signal control processor. CONSTITUTION:In a signal control processor 101, there is provided a holder terminal memory 5 for storing the holding terminal every subscriber. When there is an incoming in a trunk line trunk 104, by an off hook of a subscriber 102, a call can be done through a processor 101 and a connection control processor 100 or the like. In this case, when the subscriber 102 holds this trunk line, an accommodating position information of the trunk to be held and the information indicating an area of a memory 105 to store this are stored in the memory 105 through the processors 100, 101. Thereby, the call between the station line 104 and other subscriber can be made through channel switch 107 or the like and a held calling is not limited to the incoming from the trunk line but can be set to the calling from a private line and the calling transfer can be efficiently serviced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides a distributed control type electronic device configured such that a signal control processor controls signals from a terminal and a connection control processor controls connection to a communication network. Concerning the method of holding an extension when calling an exchange.

(Prior Art) Conventional exchanges are configured to be able to put incoming calls on a central office line on hold. In this system, only the central office line displayed on the incoming call display panel can be held; there is no means for holding other lines, such as dedicated lines, extension lines, etc. (Problem to be solved by the invention) Therefore, the dedicated line If an incoming call is received and the forwarding destination extension is busy, the person who answered the phone can either keep the phone on which it answered and put the incoming call on hold, or the line can be restored and the caller can then try again. It is necessary to pay the charge to the extension to be called.

An object of the present invention is to enable a distributed control type electronic exchange to place not only incoming calls from central office lines, but also incoming calls from dedicated lines and extensions on hold, and to easily handle calls placed on hold from other subscribers. The purpose is to provide an extension hold system that can be answered.

(Means for Solving the Problems) In order to achieve the above object, in the extension holding system in the distributed control type electronic exchange according to the present invention, signals from terminals are controlled by a signal control processor, and connection control of the communication path network is performed by a connection control processor. In a holding system in a distributed control type electronic exchange performed by a control processor, the signal control processor is provided with a memory for storing a holding party terminal for each subscriber circuit, and the connection control processor receives hold information sent from the subscriber. When a call is received, this information is identified and the storage location information is stored in the memory corresponding to that subscriber, and when information for answering a held call is sent, this is identified and the storage location information is stored in the memory corresponding to that By reading the information, the held call is connected to the subscriber who answered the call.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of an extension holding system in a distributed control type electronic exchange according to the present invention. In a distributed control type electronic exchange, a signal control processor 101 controls signals of terminals, and a connection control processor 100 controls connections of a communication channel network. The signal control processor 101 sends and receives control signals to and from the office line trunk 104, subscribers 102, 103, etc., and sends and receives signals to and from the connection control processor 100 via the processor bus 106. This signal control processor 101 contains a memo for holding terminals for each subscriber. J105
is provided. The connection control processor 100 not only controls the connection of the communication path switch 107, but also has an additional configuration for identifying terminal hold and hold call response from the subscriber circuit.

Next, the operation of each circuit section during suspension will be explained.

When a call is received on the central office trunk 104 and the subscriber 102 goes off-hook, a link of the call path switch 107 is formed between the central office trunk 104 and the subscriber 102 under the control of the signal control processor 101 and the connection control processor 100. You can now make a call. When the subscriber 102 wants to put this central office line on hold, he dials a predetermined hold access number after hooking up. This hooking and hold access number information is received by the signal control processor 101, subjected to signal control, and identified to the connection control processor 100 via the processor bus 6.

When the connection control processor 100 recognizes that the information is for hold, it sends a signal via the processor bus 106 to the storage location information of the trunk 104 to be put on hold and the information of the subscriber 102 indicating the area of the hold terminal memory 105 where this is to be stored. It is sent to the control processor 101 to store the accommodation position information of the area pressure trunk 104 of the subscriber 102 in the holding terminal memory 105.

Thereafter, for example, when the subscriber 103 answers, he dials a predetermined access code for answering a held call and the extension number of the subscriber 102 who placed the call on hold. This information is stored in the signal control processor 1o1. It is recognized by the connection control processor Zoo via the processor bus 106. The connection control processor 100 connects the held call terminal IJ corresponding to the subscriber 102.
Information to be accessed in area 105 is transferred to processor bus 1.
06 to the signal control processor 101, and the accommodation position information of the held trunk 104 is read from the held call terminal memory 105. After receiving this information, the connection fee processor 100 controls the communication path switch 107 to form a link between the office line trunk 104 and the subscriber 103,
This allows communication between these two parties. Through this operating procedure, the call placed on hold can be answered by another subscriber.

In the above embodiment, the case of trunk hold has been described, but for example, placing extension subscriber 103 on hold is performed using the same operating procedure, and a subscriber other than the responding subscriber can respond.

(Effects of the Invention) As described above in detail, the present invention provides a signal control processor with a holding terminal memory for each subscriber, and a connection control processor with a function of recognizing terminal held calls and held call responses from subscribers. By adding this, it is possible to set hold calls in the distributed control type electronic exchange not only for incoming calls from central office lines, but also for calls from leased lines and extension lines, allowing responses from other subscribers. This has the effect of providing efficient service for forwarding incoming calls.
