Abstract

PURPOSE:To avoid such a case where a subscriber forgets to call at an appointed time point or kept waiting uselessly, by using a time memory means which can store both a time point designated by a calling subscriber and the number of a calling means of a called subscriber by means of the input given from a calling means of the calling subscriber. CONSTITUTION:For an extension A, a special access code is dialed by a hooking operation and then a designated incoming time point is dialed. A central processor 4 receives an access code and the designated incoming time point from a register circuit 3 and starts a memory 5 to write an extension B and the designated time point to a time memory circuit 6 set opposite to the extension A. Then the extension A hears a service set tone through the circuit 3 at a set time point and a handset is set down. The processor 4 supplies a call signal to an extension circuit 1 from a signal device 8 at the designated time point and starts the memory 5 after receiving the answer information of the extension A. Then an answer is received from the extension B, this answer information is transmitted to the processor 4. The memory 5 is started for restoration of the designated time point corresponding to the extension A and stored in the circuit 6 as well as the number of the extension B.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cap-on device, and particularly relates to a cap-on device that is used between extensions among various service devices of a private automatic branch exchange. ] Conventional extension mutual cap-on devices monitor the end of a call when the called extension is busy, wait until the call on the called extension ends, and then call back the calling extension. Ta(
(See Figure 2).

[Problems to be solved] However, in the conventional technology described above, when the called party is busy, the caller is called back after waiting for the called party to become busy. Sometimes I forget,
Or, while waiting for a space, it was not possible to leave the seat, resulting in wasted waiting time.

That is, the conventional extension mutual cap-on device has problems such as forgetting calls and wasting waiting time.

The present invention has been made in view of the above-mentioned prior art, and aims to provide a cap-on device that can prevent forgetting to make a call and preventing unnecessary waiting time.

[Means for Solving Problems] Therefore, in the present invention, at least a communication means on the tool, a storage means for storing the state of the communication means, and an entire apparatus based on this storage means and information from the communication means are provided. In the cap-on device, the cap-on device is equipped with a control means for monitoring and controlling, and the storage means is capable of storing the time specified by the calling party and the number of the calling means of the called party by inputting it from the calling means. The system is equipped with a time storage means set at It is an attempt to achieve a goal.

[Example code] An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is an electrical block diagram of a cap-on device according to an embodiment of the present invention. In this figure, A and B indicate extensions A and B as communication means, and internal &lA and H are Extension circuits 1 and 2 are connected respectively. and a signaling device 8 for supplying a calling signal to the extension circuits 1 and 2;
A central processing unit 4 serving as a control means for monitoring and controlling the entire apparatus is connected to a switch circuit 7.

The switch circuit 7 is controlled by the central processing unit 4 and is configured to open and close the connection between the extension circuit 1.2 and the register circuit 3 that temporarily stores dial information etc. and the tone trunk 9 that oscillates a busy tone. has been done.

On the other hand, the central processing unit 4 has the extension A.

A storage device 5 is connected as a storage means that stores the status of B (busy or not), empty register information, etc., and the central processing unit 4 monitors and controls the entire device based on this stored information. It has become.

Further, a time storage circuit 6 is connected to the storage device 5 as a time storage means that can store the time and number of the called party desired by the calling party while the called party is talking. By dialing a special access code from each extension A or B using a funking operation, and then dialing the scheduled time of arrival, the information can be stored.

Next, a detailed explanation of the operation of the above device will be given.

A case will be explained in which a call arrival time is specified when extension B is called from extension A.

When the extension iA picks up the handset, the extension circuit 1 is activated. The central processing unit δ4 detects this, activates the storage device 5, finds an empty register circuit 3, and stores the extension circuit l.
The switch circuit 7 for connecting the register circuit 3 and the register circuit 3 is closed, and a tone signal is sent to the extension A.

After confirming the caller, extension A dials the extension number of extension B, transmits the dial information to central processing unit 4 through register circuit 3, and checks the status of extension B in storage device 5.

If the call is busy, a busy tone is sent to extension A from the tone trunk 9 under the control of the central processing unit 4 in the same manner as described above.

Extension A dials a special access code using a hooking operation, and dials the designated time for the first call.

The central processing unit 4 receives the access code and designated time of incoming call from the register circuit 3, activates the storage device 5, and writes extension B and the designated time into the time storage circuit 6 corresponding to extension A. When the time is set, extension A hears a service set tone from register circuit 3 and hangs up the handset.

At the specified time, the central processing unit 4 activates the storage device 5,
Find extension B stored in the time memory circuit 6,
The storage device 5 is used to check the current status of extensions A and B.

First, a calling signal is supplied from the signaling device 8 to the extension circuit l, and when response information from A is received by the central processing unit 4, the storage device 5
starts.

Next, a calling signal is supplied from the signaling device 8 to the extension circuit 2, and when the extension B responds, the response information is transmitted to the central processing unit 4 through the extension circuit 2, and the memory device 5 is activated and the time storage circuit 6 is stored. The specified time for extension A and the number for extension B are restored.

[Effects of the Invention] According to the present invention configured as described above, it is possible to prevent forgotten telephone calls and unnecessary waiting time.
