Abstract

PURPOSE:To surely report that it is a designated time even when an extension telephone is busy by referring to a storage means and when a transfer destination extension telephone is registered in the storage means, calling up the transfer destination extension telephone when the extension telephone is busy at the designated time. CONSTITUTION:The designated time is received from an extension telephone A, the designated time is registered into a designated time memory MCMEM 2, next, a transfer destination extension telephone B number is received from the extension telephone A and the transfer destination extension telephone B number is registered into a transfer destination extension telephone memory TRMEM 3. When the designated time comes, whether the extension telephone A is in an empty state or not is checked, when the extension telephone A is busy, the TRMEM 3 is checked and when the transfer destination extension telephone is registered, the transfer destination extension telephone B is called up. Thus, even when the registered extension telephone A is busy, that it is the designated time can be surely reported.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a designated time calling system in a private branch exchange.

(b) Prior Art Conventionally, a designated time paging service has been used in private branch exchanges. This is a service that calls the extension at a registered (designated) time and notifies the user that the designated (registered) time has arrived.

If the extension is busy at the specified time, the system automatically resets the time so that the extension is called after a certain period of time, or sends a special tone to the busy extension to alert the user when the specified time has arrived. I'm letting you know.

This type of designated time calling system is known, for example, from Japanese Patent Application Laid-open No. 61-1
It is disclosed in Japanese Patent No. 3851.

(c) Problems to be Solved by the Invention When an extension is busy at a designated time and the extension is called after a certain period of time, there is a problem in that the extension is called at a later time than the desired time. Additionally, if a special tone is sent to the extension when it is busy at a specified time, it may make it difficult to hear what is being said, or it may be difficult to hear if the receiver is temporarily removed from the ear. There's a problem.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a designated time calling system that can reliably notify that the designated time has arrived even if the extension is busy. .

B) Means for Solving the Problems The present invention provides a designated time calling method for calling the extension (3) at a designated time registered from the extension (5), comprising a storage means for storing forwarding destination extension 0. This is a specified time calling method characterized in that, if the extension (3) is busy at the specified time, the storage means is referred to and the forwarding destination extension [F]) is called.

(E) If the extension is busy at the specified time, refer to the storage means and transfer destination extension (B) to the storage means ((if registered,
) of the transfer destination extension.

(F) Example An example of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a block diagram of an in-line switchboard for explaining an embodiment of the designated time calling method of the present invention, and FIG. 2 is a flowchart of an embodiment of the designated time calling method of the present invention.

In Fig. 1, (1) is a control section (C
C), 12+ is a designated time memo IJ that stores the designated time.
(MCMEM), (3) is the transfer destination extension memory (TRMBM) that stores the transfer destination extension, (4) is the ring signal sending trunk (IR) that sends the call signal to the extension, (51 is the number that the extension dials) Number receiving unit (ORT)
, +6) is a timer (TIM).

Next, the operation of the embodiment of the present invention will be explained.

In step S1, the idle extension (5) goes off-hook, and the process moves to step S2. Step S2
At this point, the extension (3) is connected to ORT +51, a special number for receiving a designated time call service is received from the extension, and the process moves to step S3.

In step S3, the specified time is received from the extension, and the specified time is MCMEM! 21, and the process moves to step S4. In step S4, if the extension is in an off-hook state, the process transitions to step 8517C. In step S5, the forwarding destination extension ■ number is received from the extension (2), and the forwarding destination extension 0 number is sent to TRME.
M+31 is registered, and when the extension is on-hook, the process moves to step S6. In step S6, MCME
The specified time of M+21 is compared with the current time of TIMi71, and it is monitored whether the specified time has arrived. When the designated time comes, the process moves to step S7 to check whether the extension line is empty or not. If it is empty, the process moves to step 811. In step 811, the extension force is applied to Rf4.
Connect 1 and call the extension force. Further, in step S7, if the extension (3) is busy, the process moves to step S8, and TRMEM +31 is checked, and if the transfer destination extension is registered, the process moves to step 89.

In step S9, it is checked whether the transfer destination extension 0 is empty. If it is empty, the process moves to step 810. In step S10, l is sent to the forwarding destination extension (B).
Connect R141 and call the transfer destination extension ■. Extension (A
) or transfer destination extension B), the MC
Clear the contents of MEM+2'l and TRMEMf31.

Note that in step S8, if the forwarding destination extension number is not registered in the TRMBM 131 (such as when on-hook is performed in step S4), or if the forwarding destination extension CB) is not in an empty state in step S9, MCMEM! 21, and the process moves to step S6.

The operations from this step S6 are the same as described above.

Also, if the configuration is such that when the call to extension (A) or forwarding destination extension B) is completed, only the contents of MCMEM+21 are cleared, and the destination extension number is registered only when the forwarding destination extension is changed, the specified time will be registered. There is no need to register the forwarding destination extension number each time.

(g) Effects of the Invention As is clear from the above description, in the present invention, if the registered extension is busy at the time of calling at a designated time, it is possible to call the Ikeuchi line in the vicinity of the registered extension. Therefore, it is possible to reliably notify that the designated time has arrived.
