Abstract

(57) [Abstract] [Purpose] Conventionally, when using a transfer telephone line, day-to-day operations such as releasing transfer start were the means to manually operate the transfer telephone at the designated place. To improve this, by sending an FM signal from a remote location to the transfer telephone line,
A remote automatic switching device for call forwarding that automatically cancels the start. [Structure] For one station line, the station line circuit, communication circuit, control circuit,
It is formed from the operation circuit. The one-station line allows remote control after the transfer is released. As shown in FIG. 5, for the two-station line, two station line circuits and two communication circuits are formed for one station line, and remote control is always available.
Other models may be connected to the two circuits, and if the self-recitation NO is not input, it also has a function of switching to another model.

Description

[Detailed description of the device] [Industrial applications]

 When NTT's call forwarding service users want to change call forwarding settings urgently, it is possible to change the content settings without returning from the outside, and by setting the transfer start and cancellation at regular times It can be used without returning to operation, and the action and usage range expands.

[Prior art]

 NTT transfer telephone service subscribers only had to manually set the transfer destination telephone number, start transfer, and cancel the transfer from the telephone set up with the transfer telephone line.

[Problems to be solved by the device]

 The transfer telephone user's conventional method is a manual operation method from the telephone set with the transfer use line, and when used, it is necessary to return to the transfer telephone when changing the contents. The purpose of this device is to control the content change from a remote location by using the operation method from the transfer line telephone without returning to the transfer line installation site using a general line.

[Means for Solving the Problems]

 The first block diagram is a basic configuration diagram of a remote control automatic switching device for a transfer telephone and one station line, which is constructed by using an 8-bit CPU as a main circuit. The second block diagram is a configuration diagram when two lines are used, which is solved by a remote control automatic switching device for a transfer telephone, which has a station line circuit unit for one line.

【Example】

 Although it cannot be compared with the conventional system, the configuration related to this device is composed of 4 blocks of station line relation, control circuit, operation switch, 8 bit, and CPU. Have control. Main function The CPU has a self-remembering number storage function, a confirmation function, a fixed-period transfer start / release timer function, an automatic dial basic FM signal storage, and an automatic dial (FM signal) transmission, and accepts remote operation changes. This device, which automatically starts and cancels transfer depending on the contents, has one line and two lines. As shown in the 1st and 2nd book figure, remote control for 1 line is up to transfer release and start. When remote control reception is enabled at 2 hours and 2 lines are used, it is possible to change freely via the 2nd line regardless of time, and assuming that other devices are connected, self-recitation If you do not receive the number, you can automatically switch to another device.

[Effect of device]

 As described above, the present invention has an extremely simple structure and has a operability that is sufficient for remote operation.
