Chapter 833 CKJH-62-800
"Well, after I return to China, I will suggest the staff of our communications department to contact you." This guest himself is not in this field, but it does not prevent him from making suggestions.
"Okay, welcome you to consult at any time."
There is no distinction between high and low technology, ease of use is the last word.
"Did you see it? Although this technology looks simple, it has its practical uses." The Gauls did not forget to remind their subordinates.
As soon as he finished speaking, he saw something that he was interested in himself.
It was a very small device with a small head.
"I dare to bet, this must use integrated circuit technology." Gaul's humanity.
Not many electronic products these days are small and exquisite, especially when you see the introduction on the sign, which is a "remote switch controller".
With the control function, even if it is a simple switch -type control, there is no logical control, but when combined with "remote", it will not be too small under normal circumstances.
However, the size of the thing in front of me is no different from the 15cm disk drive seen before.
Thinking of the leapfrogging leader of Oriental people in the integrated circuit technology, the Gaul naturally naturally made this judgment.
They looked at the explanation of this device with interest.
"Ha, this is a device that can control the switch through the telephone line, and its control distance is only limited by the telephone network."
"What? That is, theoretically unrestricted?" In the eyes of ordinary people, this is the case.
"No, no, no, due to the limitations of the telephone network, its signal regeneration, relay and other functions are completed by the telephone network."
"But for ordinary people, it is equivalent to no limit. The equipment of the telephone network is transparent and does not exist."
"Genius's thoughts, exquisite technology!" A Gauls sighed.
"The important thing is that its price is not expensive."
Compared with other relatively expensive remote control equipment, although this thing is not cheap, it still looks like it was picked up for free. After all, the "remote" of other remote control equipment may not even be able to break through an urban area, and it requires expensive installation. dedicated lines or other supporting facilities.
"Well, we can buy a little." A Gaul blinked to his colleagues.
I won’t say whether to use it or not, but it is still necessary to buy some and dismantle it first. This device is very versatile.
"Look at its final introduction, I don't understand much. 'If you match the key phone, you can use the phone to control it without buying the control end device. What is the key to the key?" If you are interested in this thing Lu people, an old Maozi next to him also questioned.
"Maybe it's some of their new products. Southern comrades have made a lot of achievements in this field recently." Another old man shook his head, he didn't understand either.
But no matter not, Lao Maozi is very interested in this thing.
"What do you see? I dare to bet. This device and the" remote switch -type controller 'just now use the same technology, and even in that controller, there is a device in it. "A place in it." A place. " Lao Maozi looked at a small box next to him, very confident.
"'Low-speed remote data transmission terminal', you are right, there must be one of these things in that controller, 5 bytes per second, ha, what can this do?"
"This can do a lot of things. My Davari, don't underestimate 5 bytes per second, enough for us to do a lot of things. Especially considering that its transmission distance is limited by the telephone network." Another place Lao Maozi looked at him seriously.
Slow, but far.
"Southern comrades are simply crazy. This device is only part of the remote controller, but the price is more expensive than the remote controller." An old man complained.
"Hello comrades, this data transmission terminal is a general device, which is specially optimized, providing interface and communication control protocols, which can be used under all low -speed data transmission occasions. When there is no telephone network, a certain distance is within a certain distance. "
Our staff members answered his questions in a timely manner. In short, it is more expensive, but it is worth it.
"They can even auto-dial and auto-transmit. This thing looks like a modem, but it's much slower than a modem, but it's more expensive!"
"Because the modem requires the computer to cooperate, it does not need, comrades." Our staff is very patient, which is more expensive than the modem, but is it much cheaper than the modem+computer?
Don't look at Lao Maozi complaining to complain, but it is very fast. They directly booked a large number of, including the remote switch -type controller. These things are really useful. In terms of old words, their behavior is called "suspected goods are buyers."
The Gaul people were not willing to fall behind, and they also booked a lot.
To be sure, they all have some small calculations in mind, besides using it.
Lao Maozi placed the order, pointed to the introduction materials of the low-speed data communication terminal, and asked our staff.
"Davari, what is the equipment that mentioned‘ CKJH-62 ’?”
It is clear that the automatic dial -dial -automatic transmission on the telephone network is clear. One premise is that the exchange device of the telephone network must be this thing.
Our staff looked at it, turned around with a smile, and pointed to a piece of equipment inside: "That's it, a program-controlled telephone exchange."
Sub -control telephone switch? The hearts of Lao Maozi and Gaul people immediately itchy.
The Gauls are used mainly for vertical and horizontal switches. Their latest is the 1,000B vertical and horizontal switch with a capacity of 50,000 capacity, installed by 60 years, and the CP400 vertical and horizontal switch with a maximum capacity of 10,000. Essence
As for Lao Maozi... they are weaker. They mainly use the old-fashioned deployment and control switches of the rotating and lifting system, which is one generation earlier than the vertical and horizontal system.
But what is a program-controlled switch? Never heard of it.
There is no mistake. One post, one content, one 6 one, one book, one book, take a look!
To say that the Gauls are an absolutely high-level country in terms of overall technical level in this regard, but even they have never heard of this thing, let alone Lao Maozi.
"Davari, I remember you have imitated our 47 -type long -distance telephone switching bureau. I also participated in the relevant support work. Is this program -controlled switch related to it?" An old Maozi is indeed an old expert, and the experience is very very experienced. Rich. Lao Maozi's 47 switch is directly called the "Exchange Bureau", but it can be imagined how silly and dark.
"Ah, dear old comrade, thank you very much for your help to us." Our staff was very enthusiastic when they heard this. This is a true comrade! Be sure to thank me.
After expressing our gratitude, our staff said: "But there is little relationship between this switch and the Type 47 imitation. This is the latest program-controlled switch. The core of the control is software control. The difference is very big."
To be honest, even if this staff member is already a professionals, he doesn’t know the type 47 exchange bureau
"Ah, that's it. Congratulations, you have found your own path. Is there any inheritance between the relay and the Type 47?" Lao Maozi was still very pleased. At this time, he could see that his students had stepped out of their own way. A sense of the academic path.
"No, respectful old comrades, the relay of the type 47 switch is too precise, huge, and expensive. We use some difficulties to use. The staff of the Post Commission of the Communications Commission here is superior. After all, this gadget is super professional.
This made Lao Maozi's experts lose a bit, the control core changed, and the control device changed, and the switch would not be left. It seems that these former students have indeed taken a completely different path.
"Can you introduce this program -controlled switch?" He asked. At this time, the Gaul people listened to it. The old Mao Zi had an acquaintance here and just stubbornly.
"Good comrades ..." Our staff members were very enthusiastic. It was originally enthusiastic about guests, not to mention this is an old comrade who helped us, enthusiasm*2.
"First of all, this CKJH-62-800 you see, this is an 800 switch ..."
The opening remarks surprised both Lao Maozi and Gallic Chicken.
Just nodded, is it a 800 switch? Especially Lao Maozi can't believe it.
The core reason why deployment and control switches are called deployment and control switches, whether they are rotational, lifting, rotating and horizontal, or vertical and horizontal, is that their switching logic is realized by machinery or a combination of electromechanics, but it is mainly mechanical, especially It's the first three.
From a technical point of view, it can be said that it is full of mechanical beauty and extremely exquisite. But from a practical point of view, using machinery to realize exchange logic, think about it, the volume, the weight, the design, and the complexity are all... tear.
Most of these switches really rely on machinery to send the connector to the place where it needs to be connected. The rotation, lifting, etc. are the movement of the connector.
These methods have mechanical exercise, and the consequences are naturally slow, large wear, large noise, and large volume ...
Of course, the communication technicians did not sit still. They later made up a new thing. The full electrical electrical system was connected to the entry and exit lines with the cross matrix. Can not be used for large -scale exchange.
To simply know, 100 switches with 100 lines in lines are required for 100*100 = 100,000 relays, which cannot be used at all.
Then there was the ultimate answer to the fabric switch -vertical and horizontal switches.
