Chapter 834 What did they meet?
The vertical and horizontal system is developed on the basis of full relay, but the clever mechanical and electrical structure and continuation method are used to reduce the number of contacts from N*M of Quanji's electrical appliances to N+M.
It can be said that when it comes to vertical and horizontal systems, there is already a little shadow of program-controlled switching in it, but it still cannot change the reality that it is an electromechanical switch.
The use of precious metal contacts improves the lifespan and wear resistance, but the price also goes up quickly.
Moreover, the vertical and horizontal circuits are complex. Apart from solving the problem of switching and routing, this complex circuit basically brings no other benefits.
This is the ultimate answer to the electromechanical switch, but it is still a mechanical switch.
And Lao Maozi is even more miserable. Compared with the Gauls, their movements are a generation slower, and their things are stupid, big, black and thick. A relay ranges from half a catty to two or three catties. It is scary to think about it.
This is the main reason why this 800-door program-controlled switch scared them when it was unveiled.
This thing is too small!
For the comrades of our communication center, there may not be any feelings. The core is actually a DJS-60D and a group of relay. The rest is the peripheral components and lines. Where can it be big?
Especially with the tungsten and silver contacts provided by the high -chief worker, after ensuring the contact life and electrical performance, the contact volume of the contacts is greatly reduced, and the number of relays is smaller. The components are smaller, where can this switch be big?
If it were replaced with the C6108 or the one controlled by a microcontroller that is currently being upgraded, it would be even smaller.
But for the Gauls and Lao Maozi, especially Lao Maozi, they simply couldn't believe that such a small device could actually have a capacity of 800 doors.
This feeling is even more intense after hearing a supplement of our staff.
"The equipment that takes up the most space here is actually the patch panel..."
Lao Maozi pressed down the suspicion in his heart. Comrade Southern could not lie. They were very reputable in this regard.
He wanted to know more details about this switch. It was amazing.
At this time, some other guests also came around, watching the excitement, everyone likes it, and there are two gangs of experts from Lao Maozi and Gaul, which is also conducive to them to understand the situation of this equipment. But they are majoring in these two people.
Although they are just here to take a look, it does not prevent them from learning more.
"Davari, besides its small size, what other advantages does this switch have?" Lao Maozi asked.
"Ah, the advantage? Then there is too much! The control logic of this switch is completed by the software in the computer. There is only one relay in the computer. Therefore Fast speed, low construction cost, easy upgrade expansion, and small maintenance. "
When it comes to this matter, our comrades are not sleepy. It is really one after another, endless.
In fact, the benefits are the biggest benefits, which means that not only its own cost will be reduced, but also the area and construction cost will be reduced. At a lower complexity, the failure rate will be low. At the same time, these things will be low. At the same time, these things will be low. At the same time, these things will be low. At the same time The other effects of reduced operation and maintenance demand and reduced operation and maintenance costs can be said to move the whole body.
Although the circuit is more complicated, from the perspective of paying and income, it is still much better than the vertical and horizontal system, and the troubles brought by the complicated circuit are far less complicated than the mechanical, because the circuit is more complicated, it will not move.
But besides this benefit, there are many other benefits.
"...Thanks to the fact that the exchange is completely controlled by the program, it is very flexible and adaptable..." The guests can also guess this, otherwise why are they all interested in computers?
"...There are many new functions and new services..." Electromechanical switches are weak in this regard, because their switching logic is implemented by electromechanics, and their degree of freedom is extremely poor. They can only implement some small functions at the expense of electromechanical complexity. .
Our comrades are very broad, but when they listened to our comrades introduced some new businesses now, they were fucking.
Is this still a phone call?
If things like abbreviated dialing were realized in the era of electromechanical switches, then unheard-of functions such as scheduled wake-up calls, hotline calls, conference calls, call waiting, and call transfer made them feel that the world had changed.
In a few decades, everyone may not think of these functions specifically and have become completely accustomed to them, but these days, they are the embodiment of high technology.
"You mean that you can provide these functions in such a most basic program -controlled switch?" The Gaul people did not have a strong shock received by Lao Maozi in terms of volume. Feeling is much stronger.
The vertical and horizontal switches are already the most advanced telephone switching technology they have mastered, but in front of the program-controlled switches, they are like a child.
Especially he already knew that the switch on the spot was already the smallest category in our switch. Can these high -level functions be provided?
"Yes, these functions are basic functions regardless of the exchanges." Wuxi, the switch is divided into three or six or nine? These foreigners have the concept of grades into their bones! Our comrades criticized the Gaul in our hearts.
"There are calls here, you can try these functions." Criticism is critical, but our comrades are still very enthusiastic about inviting them to try it. This trial was excitedly excited to be excited.
If they can still find a way to implement call waiting, then call transfer is an out-and-out future technology. This function on the program-controlled switch is a set code, a flag bit and number storage space, and a transfer code. Things, and the code inside is still shared, so it is not troublesome at all.
However, even on the vertical and horizontal switches, it is basically impossible to complete. Other mechanical and electrical switches are basically at the level of thinking.
If nothing else, where do you put the transfer target number? What's more, there is also the transfer logic. Although it is just a piece of code in a program-controlled switch, it becomes a big trouble in an electromechanical switch.
The same is true of similar functions such as call meetings. For electromechanical switches, it is too complicated.
"I like this call to transfer, I need this function too much." An old Maozi sighed that many busy people who were busy with jobs were in their hearts, and there were a few people present, and there were a few of them were not busy people. Intersection
Our comrades made a fun: "Comrade, if this is the case, you can replace your unit's switch with this switch, then you can have a call transfer function."
If many other functions need to be supported by the entire telephone network, it happens that this function that most needs is not so troublesome.
This reminds Lao Maozi a little bit excited, he still has the right to speak.
"Can it be connected to our telephone network?"
Our staff laughed: "Of course, we must consider the compatibility with the outdated previous generation technology, otherwise it will not be used at all. You should know that we are very familiar with your telephone network. This aspect has been considered for a long time. On the contrary, for Gallic guests, they need to provide some information about their telephone network to successfully access.”
There is no mistake. One post, one content, one 6 one, one book, one book, take a look!
How fresh, can I not be familiar with it and imitate it.
This makes Lao Maozi not know what to say for a while. Is this the benefit of being imitated? I thank you.
And the phrase "outdated previous generation technology" sounded a bit harsh. But when he thought about that his own technology was not only outdated, but even mainstream technology might not even be within reach of the "previous generation", his heart quickly calmed down. .
You can't say that people are making fun of you, right?
"You insulted me!" "What did I do to you?" "You told the truth again!"
Think about this kind of scene, there are some things that you can't live with yourself.
"Davari, what are the benefits?" Since you want to ask, ask in the end, at least Lao Maozi himself is really interested in this thing.
"To some extent, this machine can achieve automatic detection and automatic maintenance." If our staff, let the guests almost jump up.
They can guess the automatic detection. This is a program-controlled switch with a computer. Some automatic detection will definitely not be a problem for it.
At this time, the computer is like the AI of Gao Zhendong's life. In many people, the computer is universal. As long as the computer shot, everything will be fine.
But automatic maintenance is not that simple. Maintenance is a physical job, which requires repairing and replacing physical objects.
"God! How is this possible?"
Looking at their surprised expression, our comrades were humble.
"In fact, it is not possible to complete the maintenance work, only a part can be completed."
Nonsense, what if you could accomplish everything? The guests complained inwardly.
"Now the most practical automatic maintenance function is the automatic switching of the line. When the detection is detected, the switch can control the internal switching network while issuing a warning, which can directly bypass these nodes to ensure the business to ensure the business Failure -free continuity, can even be replaced by the heat insertion of relays. "Our comrades are very humble.
He said it modestly, but in other people's ears, this seems to be the only automatic maintenance function, which is simply a blessing for the commercial operation of the switch.
The inspection and maintenance of the electromechanical switch relay is not that simple, because every function of the electromechanical switch requires a set of electromechanical logic to be realized. Fault-free continuity is a big challenge for electromechanical switches. Otherwise, I would not make the relays look so silly, big and black, just to ensure reliability.
"God, what have they discovered in the past two years? Did they meet Martians?" Martians, the top science fiction of the 1960s.
