Speaking, Lin Yun restarted the topic and said: "I inquired and found that Huachuang has a very large R&D booth, and they are developing data communication products in an all-round way, and the research projects include ISDN technology and equipment (integrated service digital network), ATM technology and equipment (asynchronous transfer network switching technology based on ISDN), network switches and No. 7 signaling forwarding point equipment.

In order not to lag behind the opponent, according to Mr. Hu's instructions, our R&D booth has already been rolled out. At present, Hushan has recruited nearly 1,000 college students, plus the Academia Sinica and Shenzhen Branch have recruited more than 300 R&D personnel belonging to the Chongguang Communication establishment, which is intended to fight to the death with all domestic and foreign opponents.

However, Mr. Hu, you don't agree with the research and development of ISDN and ATM, and ask to put all your energy into IP protocol equipment, and concentrate on ADSL, No. 7 signaling equipment and network switches.

Some of my colleagues and I in the company think that ISDN and ATM are still quite promising, after all, they are upgraded technologies derived from the telecommunications network itself, and these two concepts are now very hot in the United States. ”

Zhu Jun also said: "I also think that ISDN technology is very promising, and Huachuang is so shrewd that he will not invest money in vain."

I inquired that the telecom side has now come up with a plan for 'connecting the wires,' and plans to set up a pilot project in Puhai, with the first batch of 10,000 units to be settled! In the future, it will expand the pilot project in Beidu, Tianjin, and Guangzhou! I heard that the telecom plans to use the equipment of the American company Ascend. Huachuang must be eyeing this piece of fat, if this business develops and grows in the future, they will be released. Is it any wonder that some people are now starting to say that ISDN is It?iS? Dollars? No。 (You can earn money)

As for the ATM switch, I think the application prospect is also very extensive, and in the future, it can provide LAN access solutions to customers such as hotels, enterprises, and high-end office buildings, which is very promising. ”

Hu Yiting, as a person who came over, knew that the confusion between the two was from the heart, and he only issued orders without explaining in detail before, and he was not too thoughtful, so he answered the two seriously: "My deployment is based on strategic considerations, and the confusion between the two of you is based on the tactical level, and our focus is different, so you will have such confusion, which is normal."

ISND technology is very noisy right now, but now some experts in the world are already asking questions, saying that ISDN technology is 'I?Still?' Don't?kNo' (I don't know what it does) technology, which sounds sarcastic, actually hits the nail on the head.

The so-called integrated service digital network is actually something that traditional telephone service providers have created in order not to be eliminated by the market. In essence, it is to change the original thin telephone line into a cable, so that telephone, telegraph, fax, data, and images can be transmitted on one line. Users can install a $300 modem in their home and connect it to the digital switching support equipment in the telecommunications room, so that they can make phone calls and surf the Internet at the same time, and can also send color faxes. However, ISDN is a technology developed to protect the interests of traditional telephone service providers, and its bandwidth is only 128Kbps, although it uses high-cost thick cables, the actual speed is only three times that of 56K dial-up Internet modems. Because the backbone network needs to be shared with the telephone network, the actual download rate is often only about 1K per second during the peak period of the telephone network during the daytime, and the highest theoretical rate can only be experienced in the middle of the night. Do you think the so-called broadband of the future will be such a piece of garbage? Even if the equipment is improved and the backbone network is upgraded in the future, these chronic diseases will still be a lingering nightmare of ISDN technology. To put it bluntly, the ISDN service is just an upgraded version of the MODEM dial-up Internet technology based on the telephone network. The promotion of ISDN technology eliminates the need to spend huge sums of money to re-assume broadband backbones, which is in line with the desire of traditional telephone operators to save money.

I firmly believe that the future Internet access provider will never be able to share a network with the traditional telephone service provider, but can only start from scratch and re-assume that all the lines dedicated to data transmission are based on IP technology, and this is the future of the Internet.

ADSL technology is also the digital subscriber line technology, which looks similar to ISDN technology at the end, and it is also to buy a modem, but it is the best technology for traditional telephone line support, which does not require a special cable to enter the home, and can be directly plugged into the ordinary copper telephone line, which can avoid the trouble of countless cables to the home.

More importantly, this telephone line is connected with the data exchange in the computer room, and then directly leads to the specially hypothetical data network, instead of connecting to the traditional telephone signal network, it does not need to share the telephone backbone network with the traditional telephone service provider at all, it is a complete single dry household! It has its own broadband network! In the future, it can be upgraded as much as it wants! The backbone optical fiber can be upgraded as thick as it wants! There is no need to consider the feelings of others at all! ISDN will be a hob meat in front of it in the future, and it will not be able to keep up with the rate upgrades of others again and again, and it will always be able to maintain a turtle speed.

Therefore, as soon as ADSL technology came out this year, it had an initial theoretical rate of 1M, and in the future, with the progress of optical fiber transmission technology, it will only get faster and faster! DN technical supporters threatened that if only one user in the entire computer room is surfing the Internet, then the user can get a rate of 30M, and this is what a scammer can say! Just as funny as someone instigating you to borrow usury to start a business and do business, is there a more profitable business in the world than a usury that doubles several times a year? Do you really think that a huge computer room in the telecommunications is opened for you alone? It is necessary to have more time in the middle of the night, and you are the only one to access the Internet! Together with all the good things in the world, you are allowed to occupy it alone?

As for the ATM technology with ISDN wearing a pair of pants, not to mention, the traditional telephone technology access provider blows it like a savior, its essence is still a traditional telephone network, and the birth of a data and telephone signal hybrid creature, telephone, data, fax, telegraph, image transmission, in short, everything can do a little, but nothing can be done well, the rate is as low as ISDN, some experts in the world call it 'Another? Technological? 'Mistake', that's true.

We should not work these telephone network technologies, which are all things that will inevitably be eliminated, and in another 30 years, there will still be a few people in China using fixed telephones, which is a question mark.

What is the forefront of telecommunications technology? That is, broadband data transmission! Broadband network construction! This is the most cutting-edge technology! Our opponent in this field is Cisco! Not Huachuang!

In the future, China will invest heavily in the construction of a broadband backbone network covering the whole of China, instead of using the old telephone network; what is the most valuable thing in broadband network construction? That is, the network data exchange! The reason why Cisco was born from Xerox and has become a giant ten times more powerful than Xerox is by relying on network data exchanges!

Down with Cisco! That's what we're going to do!"

After Hu Yiting's words were finished, Lin Yun, Zhu Jun and Wu Hengyuan were already stunned, looking at Hu Yiting's radiant and sworn speech, they were deeply impressed, and felt that Hu Yiting was worthy of being a genius leader of Chongguang!
