Description

Description: TECHNICAL FIELD The present invention relates to a call origination control method for making a call by a mark-out sender method in an electronic exchange based on a stored program control method.

(Prior Art) Conventionally, when a mark-out sender method is used, when a method is decided, the caller's signal is received by connecting the caller path of the caller and the outgoing line and connecting the outgoing signal sending section with the outgoing line. Then, I passed the information to the sending part and relayed it,
The caller's dial acceptance process was normal.

(Problems to be Solved by the Invention) In the above-described conventional transmission method, when the opposite station, that is, the opposite station is a station that has gone through multiple stages, delay of the dial tone of the opposite station occurs due to signal relay. . In this case, the caller cancels the dialing process to check the dial tone and sends the call again after checking, but the confirmation time becomes longer. Therefore, there is a drawback that it may not be possible to receive and transmit signals thereafter.

According to the present invention, in the case of the mark-out sender method, the caller's dial reception processing after that can be made variable when the method is determined, and the reception processing can be continued for the time required to confirm the delayed dial tone. It is intended to provide a transmission control method.

(Means for Solving the Problems) The transmission control method of the electronic exchange according to the present invention is generally used as an interdigit timer in the transmission control method of transmitting to the trunk line by the mark-out sender method in the electronic exchange according to the storage program control method. A first register memory unit that stores a pause timer value or a long pause timer value that is set longer than the normal pause timer value; and a second register memory unit that stores a normal pause or long pause distinguishing instruction. When the output line system is the mark out sender system, a long pause timer value is set in the first register memory unit, and a pause after the station number + 1 digit is also set to the long register. The instruction is stored in the memory section, and the instruction in the second register memory section is checked every 1-digit reception, and a long pause is performed. If there is an instruction to that effect, the timer value of the first register memory unit is set to the long pause timer value so that the reception process can be continued for the time required to confirm the delayed dial tone. .

(Example) Next, this invention is demonstrated about an Example with reference to drawings.

FIG. 1 is a schematic diagram showing a relay system according to an embodiment of the present invention. In this figure, 1 is a storage device, 2 is a central control unit, 3 is a peripheral control unit, 4 is a switch unit, 5 is a line circuit, 6 is an originating side private line, a dedicated line trunk, 7 is a signal receiving unit, and 8 is a signal. The sending unit 9 indicates a private line trunk and a private line trunk on the called side.

FIG. 2 is a diagram showing a processing flowchart in the relay system of the present invention. In the figure, RMm is a register memory unit for storing an interdigit timer, and RMn is a register memory unit for storing a normal pause / long pause instruction. First, the information such as the dial of the caller is received by the signal receiving unit 7, and the central control unit 2 develops the received number in the number group stored in the storage unit 1 and, at the station number receiving stage, as shown in FIG. Perform the outgoing / incoming connection process shown. In this process, it is identified whether the output line system is the mark-out sender system or not. In the case of the mark-out sender system, the long pause timer value T ₂ is set in the register memory section RMm of the signal receiving section dedicated memory (station number reception The inter-digit timer later), and the register memory unit RMn stores the instruction in the storage device 1 (FIG. 1) so that the pause after the station number +1 digit is also a long pause. In the signal reception process, register memory unit RM for each digit received
Check the n instruction and if there is an instruction, register memory unit R
Set the timer value of Mm to the long pause timer value T ₂ . For normal pause, set the normal timer value T ₁ .

FIG. 3 is a diagram showing an operation of transmitting dialed digits showing an embodiment of the present invention. In this figure, (I) is a diagram showing a network configuration example for explaining the present embodiment, 10 to 12 are exchange stations, 13 to 15 are signal receiving units (registers) accommodated in the exchange stations, 16 and 17 are signal transmission units (senders) accommodated in the exchanges 10 and 11, 18 to 21 are private and dedicated trunks that connect the exchanges, 22 is a calling subscriber accommodated in the exchange 10, and 23 Indicates that the incoming subscriber is accommodated in the exchange 12, and the subscriber 22 of the exchange 10 is a subscriber of the exchange 12 below.
The process of calling 23 is shown.

First, in the same figure (II), there is a call from the exchange 10 to the exchange 11, the calling subscriber 22 makes a call, and after the trunk line access special number is dialed the exchange 11 number, the trunks of 18 and 19 Is received, and the exchange station 11 connects to the signal receiving unit 14 and sends a dial tone 24 to the exchange station 10. Meanwhile, the subscriber 22 waits for this dial tone, and after confirmation, starts dialing the station number of the exchange 12. This dial is transmitted from the signal transmission unit 16 of the exchange station 10 and received and accumulated by the signal reception unit 14 of the exchange station 11.

Next, in the stage (III), the subscriber 22 dials the exchange number of the exchange 12 and, after it is received by the exchange 11, the trunks 20 and 2 are received.
Use 1 to call the exchange 12. The exchange 12 connects to the signal receiving unit 15 and sends the dial tone 25 through the exchange 11 to the exchange.
Send to 10. During this time, the subscriber 22 waits for this dial tone as in (II) above, and after confirmation, starts dialing the number of the subscriber 23. This dial is transmitted from the signal transmission unit 13 of the exchange station 10, received by the signal reception unit 14 of the exchange station 11, relayed by the signal transmission unit 17, and received and accumulated by the signal reception unit 15 of the exchange station 12. It Dial transmission / reception is performed in the above-described procedure, and the calling subscriber 23 calls the receiving subscriber 23 (IV).

Thus, as the number of relay stations increases, the time required for dial relay increases, and as a result, the time required to confirm the dial tone transmitted from each relay station and the receiving station increases. Therefore, it may not be possible to confirm the dial tone of this relay station and the called station when the interdigit timer in the dial reception processing of the subscriber is in a normal time.Therefore, when making a call using this markout sender method, set a long timer in the register. By treating it, the above drawbacks are eliminated. If the interdigit timers are all lengthened in the system, the number of facilities will increase due to an increase in the invalid hold time, so only the mark-out sender method is used.

(Effects of the Invention) As described above, according to the present invention, by making the reception processing interdigit timer at the time of making a markout sender method variable (long pause), it is possible to make a call for the delay of the dial tone sent at each called station. There is an effect that it is possible to receive a sufficient signal even if the tone confirmation time on the person's side is lengthened.
