Specific problems of integrated network cabling should also be analyzed

During the design of integrated network cabling, you may often encounter different types of integrated network cabling and user requirements. Here we will introduce how to make sufficient analysis on the actual situation during the design of integrated network cabling, network Cabling cannot be the same or all in different environments.

Integrated network wiring cannot all be the same"

The telephone network and computer network cabling are two mainstream topics in the structured network integrated wiring. Which of the following products is suitable ". The "same" Technology is unreasonable, resources are wasted, and funds are wasted. Their sequelae should also be paid attention.

◆ Thoughts on integrated cabling for "all the same" Networks

GB/T 50311 chapter 3rd of the "Architectural and architectural complex network integrated wiring system engineering design specifications" states that the design should be based on users' actual needs and long-term planning requirements. We should not be scared by the possibility of influencing the future, and blindly invest in fear.

It is a good thing for the manufacturers to launch advanced products, but we should not blindly follow our feelings. We should not make it easy to change horizontal wiring; to see that integrated network cabling is not "integrated", do not follow the plausible concept.

People who support "all the same" said: I do not know whether the information points are used for voice or data. In all the design schemes, the total number of information points is calculated based on the number of voice points and data points. The so-called ignorance is just a deliberate blur. For example, a hotel, room: one voice point, one data point; office: one voice point, two data points. Another example is the home bedroom, a voice point, and a data point. What may happen to such a comprehensive distribution of information points? Do we need a twisted pair cable that is the same as high-speed data cabling? You do not have to use the same product as the high-speed data cabling product.

There may be very few work zones and information points may be uncertain. But how can we regard them as a global solution and adopt the "all the same" approach at a high cost? This approach of dealing with 10 thousand is as easy as it seems to be, but it should not be the case as a design.

◆ It is meaningless to talk on paper

The Application of Integrated Network Cabling equipment has tends to: the vertical and horizontal segments of the voice line are handed over to the snap-in module; the horizontal segments of the data line are directly connected to the plug-in module, the vertical and horizontal segments are separated by network devices. To swap voice and data information points, it is not just a patch cord change; if the two are not on the same rack or not close to each other, it is more important to do something, not just a jump ".

According to the system design in chapter 1 of GB/T 50311, there are three configuration methods for information points: minimum configuration, basic configuration, and comprehensive configuration. The minimum configuration is one information outlet in each workspace, which is increasingly rare. Among the three configuration methods, the basic configuration is the most common, and the comprehensive configuration is also based on the basic configuration of the Information socket volume. The basic configuration is to install two information modules in one information outlet, each supporting voice and data services. There is no need or no one will use the voice on the left side of the dashboard at the two information points in the same plug-in box. The jumper will be changed to the right side of the dashboard tomorrow. That is to say, telephone systems and computer LAN systems are actually two systems in the structured cabling system, each of which is relatively independent.

Integrated network wiring cannot be "all the same"

In computer LAN, fiber-to-desktop applications are also increasing. All these trends can indicate that we only want to use simple jumpers to swap voice information points and data information points. Most of them are on paper, but they are just a "all-identical" layout, it does not have much practical significance.

◆ Voice line presentation

It is confusing to say that it is "all the same". It occupies "half-day" telephone cabling. In a building, there is no "Number", not "three", not "five, malformed and become a gimmick.

Let's take a look at the voice trunk line. When we started to scratch the "all the same" wind, we said: Because the trunk lines are not as easy to change as horizontal wiring, three types of cables are still used to reduce costs. I can't help but ask: Why don't we cut down the cost even more without using a large number of phone cables? In a building group, the voice trunk lines between buildings use the telephone cables. Three types of cables are used as soon as a building is built? Later, with the passage of time, the voice trunk line of "all-identical" cabling gradually used a great number of cat5e cables. Why is it different from the original statement? It seems that in order to reduce costs, the reason is that at that time, there were no more than five types of cables available.

Let's take a look at the horizontal section of the voice line. Why isn't the voice information outlet as easy to change as horizontal wiring, but it doesn't need three types of information modules? Can it also reduce costs? Open Office or area cabling in a horizontal location. The "all the same" cabling uses over five major pairs of cables. The line-to-capacity configuration takes care of the voice points: a pair of lines/points. From this "care" point of view, the "all the same" cabling seems to understand the differences between voice and data, and realize that the line is too wasteful to configure the capacity in the "all the same" way, you may not consider the horizontal cabling, but you do not plan to change it.

The patch cords used for voice are confusing. Are three categories, five categories, and cat-5e used? Do I use single-to-line or multi-line pairs? Card connection or plug-in? Although the jumper is not so difficult to change, there are still unreasonable problems, such as waste and waste.

The cabling of voice and data points is the mainstream of structured network integrated cabling. A certain type of product is applicable to which mainstream, not which mainstream, and cannot be generalized. Five types of systems should be moderately estimated. Five types of systems are the mainstream technologies for high-speed data transmission, rather than the mainstream technologies for transmitting voice and low-speed data, such as 10 Mbps, there are three mainstream technologies for transmitting voice and low-speed data.

The other end of the voice information point is the central telephone switch. With the development of data and voice integration technology, the telephone switch will not lag. The voice information points and telephone switches are interconnected for a long time. Data and sound integration technology should be a combination of transmission and reduce information points. Otherwise, what is the significance of "integration? What's more, at that time, category 5 and Category 6 twisted pair cables may not be competent, but they will still be replaced by optical fiber cables or some transmission medium in the future.

According to the application of local computer networks, Category 5, Category 5, and category 6 twisted pair wires are connected to data information points. This is precisely the purpose of continuously developing new technologies of twisted pair wires. If we connect them to the voice information point, whether it is optimization or waste, we should analyze them carefully.
