In the figure, l is a subscriber circuit to which a subscriber's telephone is connected, 2 is a controller that realizes the overall function of the exchange, and 3 is the above-mentioned subscriber circuit. A switch network 4 accommodates the subscriber circuit 1 and is controlled to open and close by a controller 2; 4 a PB sender accommodated in the switch network 3 and controlled by the controller 2; 5 a PB sender accommodated in the switch network 3 and connected to a central office line; This is a central office line trunk connected to.

Next, the operation will be explained. - As an example, subscriber circuit l
Assume that the register signal (dial signal) from the telephone connected to the telephone is of the impulse system, and the register signal of the PB signal system is sent from the office line trunk 5 to the office line.

In the call setting phase, a register signal sent by the impulse method from the subscriber's telephone is received by the subscriber circuit 1 and analyzed by the controller 2. As a result of this analysis, if the controller 2 determines that it is necessary to send a register signal to the office line, it controls the switch network 3 to form a path between the vacant PB sender 4 and the office line trunk 5. do. Thereafter, the controller 2 analyzes the pulse train of the impulse type register signal received by the subscriber circuit 1, and controls the PB sender 4 to select and transmit the PB)-tone corresponding to the received number. The PB tone sent from the PB sender 4 is sent as a register signal based on the PR signaling system to the office line trunk 5 via a path set on the switch network 3, and then sent out to the office line.

[Problems to be Solved by the Invention] Since the conventional register signal sending system is configured as described above, the subscriber circuit 1 of the subscriber in the call setting phase
Since one PB sender 4 is required for each exchange, it is necessary to provide a number of PB senders 4 corresponding to the traffic of the exchange, which poses a problem that the device becomes expensive. In addition, in recent years, there have been many usage patterns in which databases are accessed via external communication networks, and in such cases, there is an increasing need to send impulse signals from terminals as register signals in the PB system even outside of the call setup phase. In order to cope with this, it is necessary to provide more PB senders 4, which poses a problem in that the economic burden becomes larger.

This invention was made in order to solve the above-mentioned problems, and aims to provide a register signal sending system that can simultaneously send register signals using an AC signal system to multiple outgoing lines from one tone signal trunk. purpose.

[Means for solving problems]

The register signal sending method according to the present invention accommodates each tone signal generator of a tone signal trunk including a plurality of tone signal generators in a switch network, and sends out the register signal on the switch network. The path between the outgoing line and the corresponding tone signal generator of the tone signal trunk is sequentially set and canceled based on the register signal to be sent.

[Effect]

The register signal sending method in the present invention controls the reconnection of paths on a switch network in accordance with the register signal to be sent, and controls the connection change of paths on the switch network to correspond to the register signal in a plurality of tone signal generators of a tone signal trunk. By sequentially controlling the setting and release of paths between the tone signal and the outgoing line that sends it, one tone signal trunk can realize the functions of a plurality of PB senders.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, l is a subscriber circuit, 2 is a controller, 3 is a switch network, 5 is a central office line trunk, and the third
Since these parts are the same as or equivalent to those in the prior art, which are denoted by the same reference numerals in the figures, detailed explanations will be omitted. Further, 6 is a PB tone trunk as a tone signal trunk, which is accommodated in the switch network 3 in place of the conventional PB sender 4 and controlled by the controller 2, and is 6a to 6e.
are 1 to 0 on the PB dial. 1 as a tone signal generator that continuously generates PB)-tone by two-frequency superimposed signals corresponding to each of the * and # keys.
There are two PB)-tone generators. The PB)-n generators 68 to 6g are each housed in an input port of the switch network 3, and the PB)-n trunk 6
is formed by these 12 PB tone generators 63 to 6g.

Next, the operation will be explained. During the call setup phase,
The impulse type register signal received by the subscriber circuit 1 is analyzed by the controller 2, and if it is necessary to send the register signal to the central office line, the impulse type register signal received by the subscriber circuit 1 is analyzed by the controller 2. For example, a PB)-on generator 6a that continuously generates a PB)-on corresponding to the first fold number of the register signal is selected, and the switch network 3 is controlled. A path between the PB tone generator 6a and the office line trunk 5 to which the register signal is to be sent is set up. The PB tone generator 6
The PR)-tone transmitted from a is sent to the office line trunk 5 via this path (3) set on the switch network 3, and then sent out to the office line. The same applies to the second and subsequent folds of the register signal, and the PB corresponding to the number of that digit) -
The PR) generators 6a to 6Q are sequentially selected, and the paths on the switch network 3 are sequentially reconnected to ■, . Ru.

Note that when transmitting PB)-n as a register signal, a minimum pause (silent time of a certain length or more) is required at the end of each PB)-n. All you have to do is connect to the boat for a certain period of time.

Here, the form of the switch network 3 can be applied to a space-division type one, but when applied to a time-division type one using memory, certain PR tone generators 68 to 6
No matter how many times the data of the boat to which A is connected is written as a broadcast in multiple time slots corresponding to the central office line, there will be no deterioration such as a drop in the level, so it is optimal for applying this invention. .

In the above embodiment, the PB tone generator constituting the PB tone trunk 6 generates PR)-tones using two-frequency superimposed signals corresponding to the 1-0, *, and # keys of the PB dial. Although a case has been described in which 12 tone signals are used, the tone signals of the high group and the tone signals of the low group may be superimposed by a superimposing means provided externally.

FIG. 2 is a block diagram illustrating such an embodiment. In the figure, 7 is a tone signal trunk, which constitutes a two-frequency superimposed signal corresponding to each key of the PR dial.
Seven tone signal generators 7a to 7 that individually and continuously generate tone signals of high group 3 frequencies and low group 4 frequencies respectively.
It differs from the PR)-link trunk 6 in FIG. Reference numeral 8 designates a conference trunk as a superimposing means for superimposing tone signals for each of the high group and low group sent from the tone signal generators 78 to 7g via the switch network 3; These are equivalent to those labeled with the same reference numerals in FIG.

Next, the operation will be explained. When the register signal received by the subscriber circuit l needs to be sent to the central office line, the tone signal of the high group and the tone signal of the low group corresponding to the first digit number of the received register signal are successively transmitted. The tone signal generators 7a to 7g that are being generated are selected from among the tone signal generators 7a to 7g, the switch network 3 is controlled, the two paths indicated by ■ in FIG. Connecting. The conference trunk 8 superimposes these tone signals to form a PB tone, and sends it to the office line from the office line trunk 5 via a path separately set on the switch network 3. Below, regarding the register signals after the second fold,
Processing is carried out in the same manner while changing the connection of the paths as ■, . . .

Thus, according to this embodiment, the number of tone signal generators in the tone signal trunk 7 can be reduced from the number of PB tone generators in the PB)-signal trunk 6 of FIG. input port of switch network 3 (in Figure 2, for convenience, it is drawn in a symmetrical position to that in Figure 1)
can also be reduced.

This becomes more advantageous as the types of signals are expanded.

Further, since an existing conference trunk can be used as a superimposing means, no special hardware is required.

In the above embodiment, the PR signal method was used as the AC signal method of the register signal to be sent.
It can be applied to the P signal system and the single frequency signal system, and it can also be applied not only to dial signals from telephones but also to general register signals sent from exchanges. It has the effect of

〔Effect of the invention〕

As described above, according to the present invention, paths on the switch network are reconnected in accordance with register signals to be sent, and paths between a plurality of tone signal generators of a tone signal trunk and an outgoing line are established.

Since the configuration is such that one tone signal trunk can be shared for sending register signals to multiple outgoing lines, there is no need to increase the amount of hardware even when the number of lines increases, making it economical. This has the effect of providing a register signal sending system that can realize a switching system that is advantageous for users.
