After the LEDs showing the status on each function board in the switch stabilized, Jiang Xinwei explained the meaning of these LEDs to the two operators who admired him so much: "...... The first thing you should remember is that all red lights indicate that they are generally faulty, and if they are lit, they usually indicate that there is something wrong with the function board, and all green lights indicate that the function board is in normal condition. When there is a failure, you can only check the specific fault and fault code in the computer for the time being, and find the cause and solution on the manual according to the fault code......"

After that, after a brief popularization of science, Jiang Xinwei clicked on the function menu of "Number jù configuration" on the screen.

When three submenus appeared, "Trunk Configuration", "Bureau Configuration", and "User Configuration", he clicked on "Trunk Configuration".

Because all the menus were in English, Jiang Xinwei knew that the two of them didn't know these words, so he didn't explain them anymore, but started to configure these relay numbers jù.

The so-called trunk number jù, in layman's terms, is the long-distance number jù of the switch, which is used to lead the phone of the switch to the outside, or these numbers jù are used to regulate how the number of calls jù flows when users make long-distance calls.

For the Hongxing Coal Mine switch, the number of relays is very simple: all calls to outside the switch are treated as wrong numbers, not connected and cut off.

The reason is that this switch is only used for internal use in the coal mine, and there is no need to provide an outbound circuit for the time being. Moreover, this switch is a program-controlled switch, and only the 2M digital relay port leads to the outside world, and the post and telecommunications bureau of Fengjia County does not have a program-controlled switch itself, so it cannot provide such a high-rate relay interface at all.

It is equivalent to using a donkey (the vertical and horizontal switch of the county telecommunications bureau) to drag a heavy truck (this Yankee switch), if the truck does not start, the donkey cannot be dragged at all, and if the truck starts, the donkey will be crushed to death by the truck.

Because the switch can only be used for internal calls in the Red Star Coal Mine, the number of trunks on the switch does not need to be ignored at all, and the configuration of the number of users is very simple: it is nothing more than defining the port location of the circuit board and assigning a fixed telephone number to each port.

As for the billing configuration, it is even simpler, and the billing rate of all phone numbers is set to 0, that is, all internal calls are free.

These numbers are completely mysterious in Guo Qian and Zhu Jianhua, two people who have no knowledge of process control switches, but for Jiang Xinwei, it is simply a child's house, and it couldn't be simpler.

Under the hands of Jiang Xinwei, a master, it only took three hours to configure all the numbers of this switch, which also includes him answering Guo Qian and Zhu Jianhua's questions from time to time, or taking the initiative to explain the relevant principles of the program-controlled switch, comparing it with the manual switch, so that they have a general impression in their hearts.

After the number is done, the number is loaded, that is, the number made by Jiang Xinwei in the computer (including related programs) is poured into the memory and control device of the switch itself.

When the switch was loaded, Jiang Xinwei began to calm down and take a few spare circuit boards to look at them carefully, from time to time to carefully note down a few key chip models, think about the functions of these chips from time to time, and recall from his mind whether there are similar chips that can replace them.

I have to say that the Yankees were still very generous when they sent this switch, not only filled the switch with hardware, but also provided a lot of spare parts, even more than the spare parts that ordinary manufacturers equipped themselves with when ordering products, which made Jiang Xinwei not need to remove the circuit board from the switch to have a full understanding of this switch.

Although this switch is simple, Jiang Xinwei still has a trace of expectation and excitement.

Because this is the first time he has come into contact with modern telecommunications equipment in the true sense of the word, it is also one of the target devices that he intends to design and develop.

After the computer showed that the number jù was loaded, he smiled and asked Guo Qian and Zhu Jianhua: "The number jù is loaded, and you can test the machine immediately, is your phone connected?"

Zhu Jianhua hurriedly said: "It's connected, it's already connected." …… I'll check again. ”

Guo Qian asked a little nervously, "Can it really be opened?"

Although she is now full of confidence in Jiang Xinwei, and agrees that his technology is higher than that of the experts of the Provincial Shuangzhou Municipal Telecommunications Bureau, she is still a little uneasy before the switch is opened.

Jiang Xinxu nodded and said, "It should be possible." …… Turn off the power and wait a minute before powering it up. ”

This made her think that Jiang Xinwei was not sure, and she said empathetically: "Even if it is not opened, you have done a very good job, and my father will be very happy." ”

Jiang Xinwei walked to the patch panel, looked at the line sequence of the user line, compared the label on the patch panel, and asked Zhu Jianhua: "Are your two telephones connected to 8801 and 8845?"

Now the phone number is only five digits, and this kind of factory and mining enterprises are only three or four digits, anyway, the phone number will be upgraded in the future, he will configure the switch with a number starting with 88, a picture of auspiciousness.

"Yes. I picked up the line casually. After Zhu Jianhua answered, he asked, "Do you turn off the electricity?"

"Close!" Jiang Xinxu said affirmatively.

Turning off and powering up is easy for Zhu Jianhua, and it will be done in a few clicks.

Seeing that the computer was running and stable after restarting, and seeing that the switch was slowly changing from a red light when it was just turned on to a green light, and many small green light-emitting diodes were flashing, Zhu Jianhua asked Jiang Xinwei with admiration: "Master Jiang, can I call?"

"It's okay!" Jiang Xinxu nodded and replied when he saw that the computer showed that it was normal.

The two telephones, one next to the distribution frame and the other at the manual switch, were both audio telephones brought by technicians from the Shuangzhou Municipal Telecommunications Bureau to test the switch.

Zhu Jianhua picked up the microphone and pressed the four numbers a little tremblingly: 8845.

Not only did Guo Qian stare nervously and even a little scared at Zhu Jianhua pressing the number, but even Jiang Xinwei himself held his breath.

As soon as Zhu Jianhua's four digits were pressed, the telephone connected to the other port rang with a ringing bell.

Jiang Xinxu quietly breathed a sigh of relief.

Guo Qian and Zhu Jianhua shouted almost at the same time: "It's ringing!

Guo Qian quickly picked up the microphone and asked loudly, "Hey, Zhu Jianhua?...... Can you hear me?"

Zhu Jianhua, whose ears were close to the microphone, was shocked by her huge voice, and shouted in surprise while moving the microphone away: "Can you hear it! Can you hear it! Hey, Guo Qian, can you hear it?"

"What are you talking about so loudly, my ears are deaf from you. Guo Qian shouted with a smile, "It's so clear! This voice is so good! There is no noise!"

Seeing the two young people talking loudly like children from a distance of a few steps, Jiang Xinwei also smiled happily: This feeling is so refreshing!
