JPS5875362A - Communication system of out-of-sound band signal - Google Patents

Abstract

PURPOSE:To simplify the constitution of a subscriber device without installing independently an input device, by dividing the dial information and the data information given from the same input means into in-sound band signals and out-of-sound band signals and then using either one or both of these signals. CONSTITUTION:A telephone 1 is connected to a switchboard 3 via a subscriber circuit 2, and the telephone 1 is provided with a communication mode designating switch 11 and a control part 12 which is controlled by the switch 11. The dial information and the data information are fed to the part 12 from a double contact type push-button dial switch 10. These dial information and data information are divided to a push-button dial oscillator 7 and an out-of-sound band signal MODEM9 on the basis of the communication mode designating signal of the switch 11 and via the part 12. The MODEM9 modulates an FSK signal or PSK signal. At the same time, the output of the oscillator 7 is applied to an LPF5 via talking circuit 4. Then either one or both of the PB signal given from the circuit 4 and the out-of-sound band signal from the MODEM9 is/are transmitted to the circuit 2. In such way, the constitution of a subscriber device is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an out-of-band signal communication system that simultaneously transmits audio-band amplification and out-of-band signals.

Shows Kirinari of the audio imperial outside signal S* method from Hoso 1 am.

Telephone 1 is connected to switchboard 3 for subscriber 1!1m2, and dial information and data information from push button dial switch 8 are transmitted to PR41 by push button dial switch 7.
The signal is converted into a PB number, passes through the PB number ri route 4, and is sent to the subscriber cell #2 through the low pass filter 5. on the other hand,
The audio 1N outside area number 16 is transmitted and received between the audio outside area signal transmitting/receiving unit 6 and the exchange 3 via connection #1111Mm2. The low-pass filter 5 prevents signals outside the voice band from entering the communication path 4.

Conventionally, K111 has been configured as in the company.For example, when you want to call Km3t during a call, you can use a hook switch not shown to connect a DC loop cutoff pulse or a register recall of the exchanger 3 from the voice out-of-band signal transmitter/receiver section 6. It is necessary to send a signal, ask for the dial tone from the exchange 3, and then use the push button dial switch 8 to dial &p to call the 3 parties), but the dial tone interrupts the call. was there. Furthermore, when an interrupt call is received from a third party during a call, conventionally, the user has no choice but to interrupt the call when responding to the call.

In order to eliminate these drawbacks, this invention makes it possible to transmit dial information and data information from the same human-powered means as a voice signal outside the voice zone by using a 6-mode designation method. In this way, it is possible to respond to a #g34 call during a call or an interrupted call without interrupting the call, and if necessary, a storage means can be provided, so that communication in the absence This is an attempt to make data transmission and reception easier.

Figure 2 shows that the signal within the f)lIl\i region is PB(f
An example of the configuration applied to the case of No. In this embodiment, a communication mode designation switch 11 and an &IJ monument 12 controlled by the switch 11 are installed. The dial information and data information from the two-contact type push button dial switch 10 are input manually to the control section 12, and the control section 12 inputs the dial information and data information input based on the communication mode estimation signal of the communication mode designation switch 11. Press the button dial to change the signal to oscillators 7 and 18, and change the signal to P8 to perform the audio WMM foreign communication modem and hep split, the FB signal from IGL connection 4 and the audio band from modem 9. One or both of the external signal and the external signal are sent to subscriber 1-2. At this time, if only the voice 1 out-of-band signal is specified, there is no voice out-of-band signal line low-pass filter 5 from the voice out-of-band signal modem 9, so there will be no call.

In this way, the dial information and data information from the same two-contact type push button dial switch 50 are transferred to PB (!
! Out-of-band signal and voice 11 (can be sent to exchange 3 through a pair of subscribers 1712 on one side or on the other side of No. 11. In this embodiment, 90 voice out-of-band signal modems are shown for transmitting and receiving out-of-band signals. It may be replaced with MP (multi-frequency *> signal oscillator and its receiver).

The other side of the signal L is sent to the subscriber line 2.

The low-pass filter 5 is not required when the telephone-1 is used in a non-calling manner.

In this way, the dialing information layer and data from the keyboard 13 can be changed to F8, which is an internal signal, and a signal to Pa.
One or both of the SK (i1) can send data to the exchange 3 through a pair of subscriber circuits 2.In this embodiment, the input means is a keyboard 13t41!, but a tablet,
You may also use a touch panel. In front of the audio band out-of-band signal modem 9) as an out-of-audio band signal transmitting/receiving means.
An F signal oscillator and its receiver may also be provided.

Dial information and data information from the keyboard 13 are sent to the keyboard 12 in the same manner as in the diagram M3. The input information from this keyboard 13 is stored in the memory 15 through the control 812.
It is displayed on the round display 16. The information accumulated in the memory ISK is read out to the tiijTh@12 at the time of membership fee, sent to the access li time-2 in the same manner as in FIG. 3, and displayed on the display 16. IK subscriber line/IM2
The data information sent from the exchange 3 is inputted to the -11111 section 12 through one of the voice outside signal modem 9 and the voice in-band signal modem 14. The data is stored in the memory 15 and displayed on the display 16.

In this way, the dialing information and data information from the same keyboard can be sent to the F8 in-band signal to the UPS.

It can be sent to Kokairei 3 through a pair of input terminals 2 on one side or inside of No. The data information that is coming can be displayed on the display 16, and when necessary, it can be retrieved from the memory 15 and FSK of the audio band signal can be displayed.
m or P S Kf1 and F8 of No. 16 outside the audio band
The signal and/or the #1P8Klif signal can be transmitted to the exchange 3 through the pair of subscriber circuits 2 and displayed on the display 16.

The display 16 as a hexagonal stage can be displayed using a television type display, a liquid crystal display, a light emitting diode display, a fluorescent display, or the like. Also, although it is not shown in the diagram, Jin has a memory backup battery, which is not even d5. Although the voice band 1g modem 14 is shown as an example of the voice 'fII range signal transmitting/receiving means 1d, it may be replaced with an MP signal oscillator, its receiver, and a PR value signal transmitter. Similarly, an MF signal oscillator and its receiver may be used instead of the backdoor out-of-band signal modem 90 as the out-of-band 4M@transmission/reception means.

As explained above, according to the present invention, the dialing information and data information from the same manual means can be used for one or both of the voice band internal communication, the voice band outside the voice band, and the voice input at the same time. Since a separate Kw device is not required as a means, the cost and size of the addition II' device can be reduced. You can make a 3-party call during a telephone call, respond to an interrupt call, etc. without interrupting the call. By providing a history detection means, it becomes possible to communicate when the user is absent and to send and receive data during a call. Let's meet! The 111 machine 3@ is also provided with means for transmitting and receiving dial information and data information using out-of-voice band signals 1.
