The reason, of course, is that the current exchange of the post and telecommunications bureau is too backward and cannot provide the caller ID function to telephone users, so that Jiang Xinwei can only artificially set a number as the calling number in the computer and use it as the callback number of the BP machine owner.

This cannot but say that this is a pity, but there is no way to solve this problem, and the only way to solve this problem is to wait until the post and telecommunications bureau upgrades the switch. With the program-controlled switch, with the caller ID function, the paging center can be completely automated, without the need for the calling user to report the phone number, and the paging center does not need to register on the computer.

This problem was common when the BP machine first came out, but it did not hinder the use and promotion of the BP machine, but only added some trouble to the BP machine operator.

As a supplementary measure, it is solved by manually entering the number, and the paging lady manually processes each paging call, and the process is as follows:

The calling user who needs to find someone first calls the paging center (that is, the traffic processing center of the wireless paging transmitter), the paging lady answers the call, and the calling user tells the paging lady the BP number he wants to call, and at the same time speaks the phone number of the telephone around him, the paging lady enters the BP machine number and the phone number he says into the computer at the same time, and the computer then enters these numbers into the encoder, and the encoding is transmitted by the transmitter with a wireless signal, and the BP machine receives its own code and immediately translates the phone number behind it and displays it on the BP machine screen。

This process seems to be troublesome, far less convenient than automatic paging, but the paging operators in the early stage have solved it in this way, and it has not changed until a large number of program-controlled switches appear.

In fact, this process is far less troublesome than people imagine, because at this time the number of BP machines used by ordinary people is not much, it has not yet formed a fashion trend, and the people who use BP machines are mainly unit staff, such as public security bureaus, such as railway bureaus, such as government agencies, and so on. Most of these calls are sent from the command center, dispatch center or office, the pager does not need to ask for the phone number to reply at all, the computer will automatically pop up or take the default way, and the BP machine user receives the signal, even if there is no accurate main call number, they know to call the call to reply.

Even when the program-controlled switch completely replaces the outdated switch, the manual paging station has not been completely replaced by the automatic paging station, because many people still like to use the manual station to paging for themselves.

……

Less than a minute later, the BP machine on the right rang as well.

An old worker asked in surprise: "Director Jiang, this set of equipment should be a success, right?"

Other workers, Director Wei, Mayor Peng, Secretary Sun and others all looked at him eagerly.

Jiang Xinxu nodded with a smile and said, "It's successful!"

In fact, it can only be said that the principle verification has been successful, which only shows that Jiang Xinwei has indeed mastered the principle of pager launch and related technical parameters, which has laid a solid theoretical and practical foundation for real product design.

In fact, this success is still some distance from practicality, because this test BP machine is placed in the workshop, the transmitting antenna is outside the workshop, the two are less than 50 meters apart, such a short distance can show that it is not enough to prove their performance.

In addition, whether a paging transmitter system is qualified or not is not only whether they can normally allow the called user to obtain information, but also the next step of testing, such as whether there is too much frequency drift in the test, whether the transmitting power is within the design range, and what is the signal-to-noise ratio of the transmitted signal......

These numbers are very important and are all indicators that the National Radio Commission (NCC) needs to master. If these targets are exceeded, the relevant authorities will not allow the system to be put into use.

Because of its use, it may hinder the use of other systems, and inferior signals may even hinder the normal communication of military and civil aviation, causing major accidents.

Seeing that everyone's interest was high, and Mayor Peng Ming was here, Jiang Xinwei didn't say these bad words, and acquiesced to what everyone said was successful.

After all, as long as the principle is correct, as long as they master the key parameters, the future product finalization and production will be guaranteed, there will be no major failures, at most some revisions and modifications before the product is finalized, as long as the relevant indicators of the national non-committee are met.

At this time, Su Dingyu rushed over and asked loudly, "How is it?

Seeing his nervous appearance, everyone laughed.

Su Dingyu touched his head embarrassedly, but his eyes were still looking at Jiang Xinwei. He didn't look like a powerful deputy factory director at all, just like a college student and a big boy who hadn't graduated from college for a long time.

Jiang Xinwei smiled: "Can you not receive it?"

Director Wei also smiled and said: "We have succeeded! We finally have a high-tech product." ”

Next, Jiang Xinwei simulated the operation of the pager, constantly entering the called number and caller number in the computer, and called the BP machine.

He also simulated group calls and categorized calls, each time with great success. It's just that both group calls and classified calls can only use these two BP machines as props, because they only bought these two machines at all.

Both units are fully capable and intuitive of verifying the problems associated with the entire launch system.

After the test, Peng Ming, the mayor's secretary, Director Wei, Su Dingyu, and Jiang Xinwei held a brief symposium in the conference room.

After Su Dingyu finished answering, Peng Ming said with a smile: "The municipal government appreciates your courage to innovate and break new paths on your own, and also expresses my gratitude to several of you." It's great that you've been able to make this kind of high-tech product in a short period of time. In order to do a good job in this product, in order to make this product profitable, our municipal government is also willing to help, and we are also willing to help you solve some practical problems. What difficulties do you have that we need to solve, which ones do we need to coordinate, and which ones do we need support? ”

Mayor Peng said with a smile: "Today, everyone opens their hearts to talk, as long as our municipal government has a way to solve it, as long as it helps Shengli Electronics No. 2 Factory to get out of the predicament, we will find a way to solve it, and we will give you a positive answer as much as possible." …… Who of you will talk about it?"

Even fools know who Peng Ming is here for today and why he came, so as soon as Peng Ming's words were finished, everyone's eyes fell on Jiang Xinwei's face.

The secretary glanced at Peng Ming in surprise. Although Peng Ming didn't say it explicitly, as a secretary, he knew that Peng Ming didn't want to conflict with Gu Changfeng, the general manager of the post and telecommunications equipment company, and even felt that Peng Ming was a little afraid of that kid Hu Lai.

It's not that Peng Ming is timid, it's that the Gu family's reputation is too great. Not to mention the mayor of a remote area of Yiyang City, even ordinary vice governors and governors don't want to offend them.

On the one hand, Peng Ming's words show that he really wants to help Shengli Electronics No. 2 Factory solve the problem, and hopes that Shengli Electronics No. 2 Factory will turn losses into profits. On the other hand, it is hoped that Shengli Electronics No. 2 Factory will accept it when it sees a good situation, and the government will give them preferential treatment and care here, so that they will not go to the post and telecommunications equipment company to entangle.
