Abstract

PURPOSE:To attain transfer for a pushphone telephone set even if no abbreviation function service is offered to the telephone set by storing a telephone number of a telephone set to be transferred to a dial data memory or a switch. CONSTITUTION:The number of the telephone set to be transferred is stored in the dial data memory IC or the switch. When a telephone set 1 calls another telephone set 2 in this state, a call signal is given to an incoming telephone set 4 from a controlling telephone station 3, the signal is detected and the stored dial number data is called, the data is converted into a digital data and a PB signal, then outputted. Then the controlling telephone station 3 is called and the telephone set 1 calls the telephone set 8 to be transferred.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a telephone transfer device that is capable of transferring calls even to telephones that do not receive the shortcut function service.

A device that automatically forwards incoming calls to the forwarding destination phone at the local office when you are away from the office is already commercially available under the trade name Telephone Transfer Device δ. has been done.

Conventionally, the known telephone transfer device is required to be equipped with at least one so-called Button telephone that receives short 1IT function service, and if the telephone is not equipped, call transfer is not possible. It was impossible. This is because the call transfer device utilizes the shortening function of the button telephone to shorten the transfer time.

However, there are two types of butshuhon telephones: those that receive the shortcut function service and those that do not receive the shortcut function service. Previously, telephones that did not have the shortcut function service could not transfer data. .

However, the present invention allows this to be done even if the telephone does not receive the shortcut function service, as long as it is a button telephone.

First, the transfer device referred to in the present invention will be described as follows.
Figure 1 shows an example of this.In the figure, 1 is the ear-shaped product temperature, 2 is the telephone station to which the ear-shaped product temperature 1 belongs, 3 is the central telephone office, 4 is the incoming telephone in the office, and 6 is the same telephone station. Conventionally, the calling telephone 6, which is installed in an office, has always been a telephone that receives the shortcut function service.

Reference numeral 5 designates a transfer unit attached to each terminal of the incoming telephone 4 and the outgoing telephone 6, 7 the forwarding destination telephone office, and 8 the forwarding destination telephone at the outpost office.

In FIG. 1, when the incoming telephone 4 is called by the ear type temperature l, the call is placed on the incoming telephone 4 via the telephone office 2 and the central telephone office 3. At this time, when the office is away, the transfer unit 5 operates according to the well-known transfer theory, and the dialing telephone 6 dials an abbreviated automatic dial (for example, 03-344-
2700 is abbreviated and memorized as *00) to the controlling telephone station 3, calls the forwarding destination telephone 8 via the telephone station 7, and enabling the ear mold temperature l and the forwarding destination telephone 8 to talk. This is what I was looking for.

However, while the calling telephone 6 of the known example conventionally required receiving the shortening function service as described above, the present invention does not require the shortening function service. Both are new inventions because a simple butshuphone telephone (P-B tone) is sufficient.

Examples of the present invention will be described below.

FIG. 2 is a configuration block diagram of the transfer section 5 of the present invention, where 9 is a B terminal connected to the incoming telephone 4, IO is a bell detection section of the incoming telephone 4, and 11 is a B hold relay of the incoming line. ,
12 is an audio coupling transformer for the incoming telephone 4; 13 is a line recovery detection section for the incoming telephone line; 14 is a bidirectional amplifier;
5 is a link relay between the incoming telephone 4 and the outgoing i [temperature 6;
16 is an audio coupling transformer for the outgoing telephone 6; 17 is a C hold relay for the outgoing telephone 6 line; 18 is the outgoing telephone 6
A C terminal connected to the line, 19 a line polarity detection unit for the 6 lines of the calling telephone, 20 a control unit for the B hold relay 11,
21 is a master reset control section of the transfer section 5, 22 is a control section of the link relay 15, 23 is a reset timer of the transfer section 5, 24 is an external reset input terminal, 25 is a pull amplifier resistor for resetting the external reset input terminal 24, 26 is C
C relay control section of hold relay 17, 27 is transfer section 5
28 is the master clock of the transfer unit 5; 29 is the main control unit of the transfer unit 5;
is an auto-dial control section of the transfer section 5.

Next, we will discuss the effect.

Prior to operation, check the dial data memory IC shown in Figure 3.
Alternatively, the telephone number of the transfer destination telephone 8 may be stored in the switch 38.

In this situation, when the earphone telephone station 2 is called at the earphone temperature l, a call is placed from the central telephone station 3 to the incoming telephone set 4, and this is detected by the bell detector lo. ), main control section 27
The C relay control unit 26 is activated, and the dial number data that has been written or set in advance in the serial dial data input terminal 33 is read out from the P-B) output terminal 37, and the serial-to-parallel conversion unit At 31,
This is converted into 4-bit parallel data, the data is converted into a corresponding dial number in the P-B tone IC control section 32, and the output is sent to the P-B tone generation contact and circuit 35.

The digital data is converted into a PB signal by the P/B tone generation IC 36 and sent out from the PB tone output terminal 37.

Then, the audio coupling transformer 16 and the C hold relay 17
is connected to place a call to the central telephone office 3, and the ear-shaped product temperature l makes a call to the forwarding destination telephone 8. By lifting the handset of the forwarding destination telephone 8, the C terminal 18 is called.
A polarity reversal occurs, which is detected by the line polarity detector 19 and output to the main controller 27. As a result, the control section 20 is activated to connect the B hold relay 1ltl-, and the generation of the message tone is controlled by the message tone control section 30 and the auto-dial control section 29 for a certain period of time.

After that, a control signal is applied to the control unit 22 from the main control unit 27, the link relay 15 is connected, and an activation command is applied to the bidirectional amplifier 14, so that the ear mold product temperature l and the forwarding destination' telephone 8 are connected to the communication unit 7i.
This results in an fI state.
