Description

DETAILED DESCRIPTION OF THE INVENTION A similar conventional call connection device includes an outgoing trunk for signal transmission in the case of pager ringing and an output trunk for signal transmission in the case of response operation regarding the method of connecting the exchange and the call connection device. There are devices that connect with three types of circuits: a relay trunk and an extension circuit for dialing, but these require two types of trunk levels for outgoing relays to be prepared on the exchange side. There are problems such as having to install a separate extension circuit and also equipping the call connection device with a dial center circuit for sending out dial signals, which puts pressure on the exchange and puts more stress on the call connection device than necessary. Many inconveniences occur, such as having to deal with price increases, and depending on the conditions, it is often impossible to put this device into practical use if it is not possible to set two levels on the exchange side. In many cases, this leads to the necessity of abandoning the realization.

Furthermore, since the burden of dial center equipment on the call connection device greatly affects its price, implementation is also not a good idea for realizing the present device. FIG. 2 shows a conventional example. An outgoing relay trunk 16 for pager calling and an outgoing relay trunk 17 for response operations were required. When the person carrying the called pager makes a response operation using the telephone, the control circuit 18
By using the calling telephone number stored in the memory circuit 12 by the center 19, the calling telephone is called through the telephone connection terminal of the exchange to which the telephone is to be connected. This serves as the exchange extension circuit for dialing as described above. The present invention is directed to providing a pager calling type automatic call connection device that completely eliminates these absurdities.

Since the main parts of the present invention are clearly shown in FIG. 1, a detailed explanation will be given according to this figure. First, in the case of a pager call, if the calling telephone 1 dials the level number 1, the pager calling number 0, and the calling telephone number, the dialed number will be captured by the exchange 3 to the outgoing relay trunk 4. The signal identification circuit 8 of the automatic call connection device 1 is connected by the outgoing relay trunk 4.
The pager calling number and calling telephone number are sent to the caller. Here, whether the sent signal is for a pager call or a response calling telephone call is identified by the number of dialed digits or the composition of the dialed number, and the pager call information is determined. Control circuit 1 with same number information
0・＼Send. Control circuit 10 receives an information signal indicating whether the pager is ringing or answering, and a number information signal consisting of the pager calling number and the calling telephone number. Since the information signal just sent is for a pager call, the control circuit 10 sends the pager call number to the pager call signal generator 13. The pager calling number signal is converted into a pager calling signal by a pager calling signal generator 13, and transmitted through a radio wave transmitter 14 as a calling radio wave from an antenna 15.

The pager corresponding to the pager calling number receives this calling radio wave and displays an incoming call.

When the series of ringing operations is completed, the pager dialing number and the calling telephone number are stored in the memory circuit, and at the same time a completion signal is sent back to the calling party's telephone via the exchange, so the handset can be restored and a response can be made. wait. In addition, when the recipient of the pager who receives the call dials the predetermined response operation from the nearest telephone 2, that is, dials the level number, the pager calling number, and the specific number, the dial signal is sent to the exchange 3 and transmitted to the outgoing relay trunk 4. is captured and sent to the signal identification circuit 8 in the automatic call connection device 7 via the outgoing trunk 4. Here, the above level number is the same as the level number at the time of calling. However, in the case of the digit number detection method, it is not necessary to dial the specific number. Here, the transmitted signal is identified as a pager call or a dial for response by the number of dialed digits or the composition of the dial number, and the response operation signal information and the same pager number information are sent to the control circuit 10. send to. The control circuit classifies the sent information signals, and in the case of response operation information, reads out the previously stored voice telephone number and calling telephone number from the memory circuit 12, and sends the calling telephone number to the telephone number information sending circuit 11. send. The telephone number that has arrived at the circuit is sent to this telephone number information sending circuit 1.
1 for example the well-known 1 out of 10 chord (
(2-out-of-5 code, BCD code, etc.) and sent to the center circuit of the exchange operator's desk via the connection circuit 9. The center circuit of the operator's desk performs dialing for the exchange operator based on the same number information that has arrived, and places an incoming call on the calling telephone 1 via the exchange 3. When the caller answers on the telephone 1, the connection circuit 9 is switched, and the communication circuit is connected to the calling telephone 1, the communication trunk 5 in the exchange 3, the exchange operator's desk 6, the connection circuit 9, the identification circuit 8, and the output relay. It is formed by a trunk 4, an exchange 3, and a telephone 2, and can achieve the purpose of mutual communication. Further, in an extension PBX, a relay stand (exchange operator's stand) is indispensable, and the present invention uses a relay stand with this center function without installing a center in the automatic reporting device.

As described above, this device does not impose an unreasonable burden on conventional exchanges by increasing the level, and it is also possible to use one level in common for signal transmission for calling and answering operations, resulting in an efficient and rational usage method. In addition, the center circuit was omitted and the center inside the existing operator's table was used to streamline the equipment.
