Jiang Xinwei smiled bitterly and replied, "I'm sorry, I'm not from the Yiyang City Telecommunications Bureau,...... , my home is in Yiyang City, Fengjia County. ”

The young man smiled and said, "I'll just say I haven't seen you." …… , You are Fengjia County, then do you know the Hongxing Coal Mine in Fengjia County?"

Jiang Xinwei nodded and said, "My home is not far from the Hongxing Coal Mine. …… Do you have acquaintances in the Red Star Coal Mine?"

The young man laughed and said no, "No." We're going to go to the Red Star Coal Mine to open a Yankee switch. I would like to ask you what are the fun places over there and if there are any delicious specialties. I have a classmate from the Department of Posts and Telecommunications who will also go to investigate. ”

Speaking of the classmates from the Ministry of Posts and Telecommunications, this young man deliberately raised his voice a little, his eyes couldn't help but show a little pride, and he glanced at the technician of the provincial management bureau next to him.

Jiang Xinwei was stunned for a moment and asked, "Didn't our county post and telecommunications bureau open that switch?"

He was quietly happy in his heart: When you know that the switch has been turned on, I don't know what you will think, hehe.

The young man smiled and said, "You guys have a post and telecommunications bureau in Lingjia County? Hehe, can you open it? It's not that I'm bragging, you can't open it even if you tie it together." Do you guys from the county bureau see the process control switch? …… I'll tell you, now we have taken over the opening of this switch, and we have also set up a project in the city bureau. When the time comes, if you can squeeze in and participate in the opening work, you can get some rewards, and you don't want to sue others......"

Jiang Xinwei couldn't cry or laugh for a while, and was thinking about whether to tell the other party that the switch had been turned on, when he saw that there were many people on the rostrum, and everyone stopped talking, and the technician who was talking to him just now also leaned back and sat up straight.

Several foreign guests came out accompanied by city leaders, school leaders, and leaders of the Provincial Post and Telecommunications Bureau. There was a girl in the crowd who caught the extra eye.

She is Leng Lan, who serves as a translator for foreign guests.

Standing in the pile of men, Leng Lan is like a cluster of new lotus, elegant and innocent, she has the beauty of a southern woman, and the tallness of a northern woman. At this time, she was listening attentively to the speeches of foreign guests and leaders, ready to translate at any time, but her eyes were quickly searching the crowd under the stage.

Jiang Xinwei knew that she was looking for herself, but he also knew that she was just looking for him subconsciously, and she didn't have to find him, so he didn't move, he still sat upright, his body sitting straight, and his eyes looking ahead.

Soon, she saw him, her good-looking eyes blinked, but immediately moved away, lowered her head and looked at the information in her hand very seriously.

After the foreign guests and leaders sat down, the school leader, as the host, only said a few opening remarks, which was nothing more than a brief introduction to the names and identities of the main foreign guests and leaders, and what to welcome and thank.

After a while, the speech began.

The first speaker was a young foreigner in his thirties, and his speech was on the application of multi-channel carrier technology.

Although carrier technology is also a technology in the field of communication, it is obviously very different from the content of the No. 7 signaling that the host said in advance, not to mention that this foreigner is talking about analog carrier technology.

Others may not know, but Jiang Xinwei knows that this technology is a technology that is about to be eliminated, if it is a small enterprise to tell these nothing, but for this university that strives to be at the forefront of technology, for the leaders of the Provincial Post and Telecommunications Administration to participate, they talk about these backward technologies with such fanfare, it is a bit of a fuss, a little look down on people.

Listening to it, Jiang Xinwei heard the clue, the dare lover family did not come to our country to exchange technology, but to promote their products. To be precise, he came to promote the inventory products, but except for Jiang Xinwei, no one else knew about it.

Jiang Xinwei looked at the leaders who accompanied the foreign guests on the rostrum, and couldn't help but feel sad in his heart, and at the same time he remembered some other things in his memory:

At present, both China itself and Western countries know that China has a huge market where the telecommunications industry has not yet started, and this market can accommodate a large amount of telecommunications equipment and store huge profits that are coveted by Western telecommunications companies.

Western enterprises are not good guys, they know that China is now eager to develop its economy, eager to break through the embargo of Western countries, and eager to obtain advanced technology from them, so they have played small tricks with our government and enterprises, and sold their backward products and inventory products to China at high prices.

Jiang Xinwei remembered that in the previous life, many small Western enterprises sold a lot of Ericsson's old user switch equipment that had been used and eliminated and could only be thrown away as garbage to Huaxia in large quantities, occupying a large market in Huaxia.

At that time, the country was only opened, our technicians looked at the western developed countries everything is good, although these old user switches are old, but their performance is far more advanced than those stepper and vertical and horizontal switches that are being used by the post and telecommunications bureau in China at that time, not to mention that there are many places in China that are using manual switches, since the price of the new switch is too high, then buy the old one to make do with it.

It was not until China's self-developed large-scale program-controlled switches appeared and began to be put into use that this situation slowly changed.

The foreign guest who is here today is a technician from the Italian company Etna Communications, who is shamelessly selling analog multiplex carriers that cannot be sold in Europe, the United States, and Japan under the guise of technical exchanges.

A carrier is a signal transmission device. The so-called transmission device, to put it simply, is a device that can transmit a telephone signal from one switch to another switch at a distance. Without them, people can't make phone calls over long distances. This device is capable of sending the voice signal of the switch to another switch tens of kilometers, hundreds of kilometers, or even thousands of kilometers away.

Their principle is that the carrier turns the voice signal into a carrier signal and loads it into a copper wire or copper-clad steel wire for transmission.

Generally, there are only a few or dozens of call circuits that can be provided by the carrier at the same time. However, China's carrier machine is even more backward, and the carrier used by many rural post and telecommunications offices even has a single-channel or double-channel capacity, that is, only one or two people are allowed to make phone calls with people in a distance.

With the development of China's economy, more and more people use telephones, and this kind of small and easy transmission equipment is obviously not good, and must be updated. If you can combine this Italian communications company

By replacing the carrier equipment that China is currently using, it will be able to increase China's telecommunications capability tenfold or dozens of times.

Shouldn't my country buy this kind of equipment?

No!

Because now there is a new technology that is being developed, and its emergence has knocked away the advantages of the Italian company's products. It is precisely because of the development of this technology that the carrier produced by the Italian company has suddenly exceeded demand in the past and is basically unpopular now, and the company has also suffered unprecedented losses. In the past, they did not bother to sell their carrier products to China, but now they have to send people to sell them in person, and they have to use various names to fool China's experts and China's post and telecommunications departments.
