Abstract

PURPOSE:To use a master file as a database when a telephone line is connected in no ringing by incrementing digit number of a station number sequentially by one when connection is disabled within a prescribed time so as to increase transmission digit number of a 2nd dial. CONSTITUTION:When data collection is started, a dial transmission means 12 reads at first a 1st dial from a master file 11 and sends it via an NCU 13. The 1st dial sends a series of number with a toll station number, then it is received by an NRT 22 as a no ringing service request. Then a data of a telephone set 3 is read from the file 11 and sent as a 2nd dial. In this case, a data of low-order 5 digits comprising 4 digits of individual dial number and 1 digit of local station number is set at first as the 2nd dial signal. When no connection is attained within a prescribed time, a digit number of station number is incremented sequentially by one to increase the transmission digit number of the 2nd dial. Thus, the 2nd dial is set while being corrected into the digit number of the local station number.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a dial command device for a no-ringing NCU.

(Prior Art) In recent years, methods have been used to collect a large amount of data using general telephone lines. Additionally, in this case, a no-ringing service is provided that connects without ringing a bell.

When requesting this no-ringing service, a specific telephone number determined for each region (hereinafter referred to as the 1st dial) is commanded, and then an individual telephone number of the desired party (hereinafter referred to as the 2nd dial) is commanded. ) allows you to connect without ringing the call bell.

When the first dial is commanded, the N
With RT (no ringing trunk),
A call bell signal is not sent to the second dial telephone (terminal) that is subsequently instructed.

Furthermore, the system is such that the no-ringing service is reset when a telephone number with an area code is commanded as the second dial.

(Problem to be Solved by the Invention) In order to sequentially connect to a large number of telephones (terminals) with different telephone numbers and collect data, a master file in which a large number of telephone numbers are recorded is used. The phone number recorded in this master file is the area code, local code,
There is no problem if the individual dials can be distinguished, but for some reason, they may be recorded as a series of numbers and cannot be distinguished.The present invention provides a dial command device that can be connected even in such cases. It is an object.

[Structure of the invention]

(Means and Effects for Solving the Problems) In order to achieve the above object, the present invention provides an apparatus that transmits a second dial requesting connection to an individual telephone after transmitting a first dial commanding no-ringing. A file in which the individual telephone number is recorded as a series of numbers, and a number read from the file consisting of the last 5 digits of the series of numbers, including the 1-digit area code and 4-digit individual dial, are sent as a second dial, and the number is read out from the file as a second dial. This dial command device is provided with a dial sending means for increasing the number of digits of the second dial by sequentially increasing the number of digits of the station number by one when the number of digits is not connected.

(Example) FIG. 1 shows the main structure of an embodiment according to the present invention.

FIG. 1 is an example in which a data collection device 1 sequentially collects data from a large number of telephones (terminals) 3 via a telephone office 2. In FIG.

The data collection device 11tl includes a master file 11 in which a first dial and a second dial are recorded as a series of numbers including an area code, and a dial sending means 12 that reads the data and outputs a dial command to the NCU 13. and a data collection means 14 for organizing and recording the received data. The telephone office 2 is equipped with an exchange 21 and an NRT 22 that stops sending out a ringing bell signal when the first dial is received.

In the above configuration, when opening and closing data collection, the dial sending means 12 first reads out the first dial from the master file 11 and sends it out via the NCU 13.
The first dial is received by the NRT 22 as a no-ringing service request by sending a series of numbers with an area code. Next phone (terminal) from which data will be collected
3 (telephone number) is read from the master file 11 and sent out as the second dial. In this case, since the data read from the master file 11 is a continuous number with an area code, if N is sent as it is, the no-ringing service will be reset, so the following procedure is performed.

The series of telephone numbers recorded in the master file 11 is
Area code consisting of 2 to 5 digits, city code consisting of 1 to 3 digits, 4
It consists of an individual dial number consisting of digits, so first
For the first time, the last five digits of data including the four-digit individual dial number and one-digit local area code are extracted and sent as a second dial. If the local area code consists of one digit, this first
Connected on the second dial. If the local area code is two digits, this first second dial will be a disconnect. The dial sending means 12 is equipped with a diagnostic timer that determines disconnection, and when the connection is not established within a certain period of time (for example, 30 seconds) after sending the second dial, it is determined that there is a disconnection, and the second dial is sent a second time. . In the second dial, the last six digits of the local code are extracted and sent. City code is 3
If it is a digit, the second dial is also disconnected, and the third dial extracts the data of the lower seven digits and sends it out. In this way, the correct second digit of the local code is
The dial is sent out. The maximum number of digits for a local area code is usually 3 digits, so if it is determined to be disconnected when the third 2nd dial is sent, the data for that phone number is stored in another memory as the line is in use (busy). The next telephone number is read from the master file 11 and the second dial is sent in the same way.

FIG. 2 shows an example in which the master file 11 shows the relationship between recorded data and a sending dial.

In the same figure, the first telephone number is 0123 (45) 678.
9 indicates the first dial, and the second and subsequent dials indicate the second dial.

Further, the numbers on the left side of the sending dial indicate the number of times the dial signal is sent, and the symbols C and D on the right side indicate connect and disconnect. For the first dial, the master file data is directly sent as a dial signal, and the connection is made once.

The second and third dials have two-digit and three-digit local area codes, respectively, and are connected the second and third times, respectively.

FIG. 3 is a flowchart showing the main part of the processing procedure after reading the second dial. After the connection is completed, data collection processing begins, and after missing data processing, the next second dial is read from the master file and the same processing is repeated.

〔Effect of the invention〕

According to the present invention, when connecting a telephone line in a no-ringing manner, a dial command device can use a master file as a database in which a telephone number to be commanded as a second dial is recorded as a series of numbers including an area code. can be provided.
