Abstract

PURPOSE:To attain originating from a PB subscriber to a mark-out line, by discriminating the end of a receiving number by the inter-digit timing over of the receiving number or specific code reception in case of originating from the PB subscriber to a toll network in a private electronic exchange of a private route network using mark-out connection method. CONSTITUTION:When a PB subscriber's PBTEL is off-hooked, a subscriber's PBTEL is connected to a PB originating register trunk PBORT on the exchange side and a dial tone DT is sent to the subscriber's PBTEL. After hearing the DT, the subscriber's PBTEL dials a terminating subscriber's number. After storing the dial number and receiving the prescribed number of digits, the exchanged EX side discriminates whether it is extension subscriber terminating or mark-out line connection, and when the mark-out line connection, connects the trunk TRK of the catched mark-out line to a DP sender trunk DPOST and sends the PB dial code received from the subscriberr' PBTEL as the DP. In the application, the PB subscriber of EPBX can dial a number continuously independently of the mark-out line.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to an electronic private branch exchange (hereinafter referred to as EPRX), and in particular to a push-button dial telephone subscriber (hereinafter referred to as PB) for a mark-out line. (referred to as Subscriber)
The present invention relates to a connection control method using a register Φ sender method when transmitting a signal.

(2) Conventional technology and problems Conventionally, when a PB subscriber of an EPBX makes a call to a markout line, the signal system of the markout line is the ear pulse (hereinafter referred to as DP) signal system, so if the PB subscriber of the EPBX makes a call to the markout line, the I couldn't.

The outgoing connection formats for lines with different signaling systems are:
There is a conversion sender system that converts a PB double signal to a DP double signal and sends it out, but with the conventional conversion sender system, a PB subscriber could not make a call to the mark-out line for the reasons described below.

(b) Frequency m of the second tone (hereinafter referred to as 21st T) returned from the Toll network when making a call to the markout line
Since the number and level are undefined, there is a risk that the PBREC may malfunction in a method in which a pushbutton signal receiving device (hereinafter referred to as PBREC) is connected to the communication path.

(b) If the second DT cannot be heard during multi-stage relay connection, if the subscriber presses the PB and accordingly sends the DP, the minimum pause cannot be achieved, which may cause bile fluid or non-contact.

On the other hand, without returning the second dial tone to the subscriber, dial all the digits Z.
, the above-mentioned disadvantage does not occur in the register/sender system in which the PBREC is disconnected after the dialing is completed and the dial information is sent to the toll network.

However, in the all-digit storage/reproduction method, since all the digits are stored and then transmitted, it is necessary to detect the end of the received digits. In the conventional system, the number of digits is identified by the received digits, but because the markout line is an open number system, the number of dialed digits is not uniquely determined, and if the final digit is identified by the received digits, the following problems occur. appear.

■ As the network becomes wider, the amount of number expansion tables (memory) used to identify the final digit becomes extremely large.

■ When changing the network configuration (for example, adding a slave station or a grandchild station), it is necessary to change or add contents to the number expansion table (memory).

Due to reasons such as ■■, the guardianship has become very complicated,
It also has the disadvantage of low flexibility in future network expandability. For the above reasons, the conventional all-digit storage and reproduction method that identifies the number of digits based on received digits cannot be adopted.

(3) Purpose of the Invention The purpose of the present invention is to apply the all-digit storage and playback method, which is a type of register sender method, to enable calls from PB subscribers to markout lines.

(4) Structure of the Invention In order to achieve the above object, the present invention provides a method for transmitting PB dial signals received from PB subscribers in a horizontal electronic switchboard of a private route network using a markout connection method as an inter-office signaling method. It is equipped with a means for converting the signal into a DP dial signal and transmitting it to the markout line, and when a PB subscriber makes a call to the toll network, it is determined whether the received digits end due to timing overage between digits of the received digits or reception of a special code. It is characterized by carrying out the following.

(5) Examples of the Invention The present invention will now be explained in detail with reference to Examples. Figure 1 (a
L (b) Figure d is a configuration diagram illustrating the originating connection form to the markout line. In Figure 1(a), PB
When the subscriber P B T E L goes off-hook, the exchange connects the subscriber P B T E L to the PB register trunk 1) BORT, and sends a dial tone D to the subscriber PB.
Send T.

After hearing the DT, the subscriber P B'T E L dials the called party's number, and the exchange E Identifies whether it is an out line connection with l-, and the trunk T of the markout line captured when the markout line is connected.
Connect the RK and DP sender trunk DPO8T, and send the PB dial code received from the subscriber's BTEL as DP.

On the other hand, FIG. 1(b) shows that when the subscriber's PB location is off-hook, the PB register trunk PBR8T
and returns the caller's DT to the subscriber's PB. When the subscriber PB dials the marked-out line access code + the 1000 number, etc., the exchange EX captures the trunk TRK of the marked-out line, receives and stores it, and sends out the numbers as a DP dial.

In general, a markout line sends outgoing digits (Dl) one after another to a destination station. The dialed digits sent here are based on an open number system, that is, the number of digits cannot be determined.

Therefore, in PBR8T, the received digits are transmitted after all the digits have been accumulated, but since the markout line is an open number system, it is not easy to identify whether the number of digits in the received digits are the same.

Therefore, as shown in the timing chart of FIG. 2, the present invention monitors the timing between the digits of the received digits, and if the next digit does not arrive even after a predetermined period of time has elapsed, the dialing ends at that timing. It is assumed that this is the case, and the process moves to the process of sending DP digits to the markout line.

In Fig. 2, (a) shows the received digits, and (b) shows the sent digits.7 Now, subscriber P's device is dialing PB dials A, B, C.
.

If you dial X, after receiving the final digit X, t
. As the seconds elapse, the dial reception is completed, and the received and accumulated digits are counted as t as shown in FIG. 2(b).

Seconds later (after startup χ7 from trunk TRK), B number,
After the passage of tI, the number C is sent out, and after the elapse of j+seconds, the number X is sent in this order.

On a markout line, PBR8T starts transmitting the number when it finishes receiving a dial, but since the other station is a subscriber station to the markout line, it transmits the subsequent number after confirming that the game has started up. I have to.

However, in reality, in the case of a multi-stage relay connection, etc., the EPBX needs to know how many intermediate stations are there and take the minimum pause to start the game accordingly, which is not practical. Therefore, a pause sufficient to activate the game is added between the digits of the number to be sent, and then the number is sent. (T, ~1+ in Figure 2) As a method for determining the end of dialing, it is also possible to use a method in which the subscriber presses &+F'Madahaゞ#'' at the end of dialing, and the EPBXO determines that code. .

FIG. 3 shows Atayal numeral A as another embodiment.

After receiving B, C, and X, special code [-X-), ! , or [#], etc., it is considered that dial reception is complete.

According to one embodiment of the present invention, there is an effect that a PB subscriber of an EPBX can dial numbers consecutively without being aware of marked-out lines.

(6) As described in detail, according to the present invention, EPBX's PB subscriber can dial without being aware of the marked-out line, so that the second DT from the other station cannot be heard. , there is no chance of missed data, and since the data is retransmitted after all the numbers have been accumulated, there is an effect that malfunctions of PBR, EC, etc. caused by the second DT are eliminated.

Furthermore, it eliminates the need for a number development table (memory) for identifying the final digit, and has the advantage of being able to flexibly respond to wide-area networks.
