The difference between telephone line and network line
How to judge the telephone line and the network line
1. The network cable can be used as a telephone line
In addition to being used to surf the Internet, you may not know that the network cable can be used as a telephone line because the telephone line only needs 2 cores.
2. The telephone line can be used as a network cable depending on the situation
The general telephone line is 2 cores and can only be used as a telephone line. And sometimes the phone line is 4-core, such as the phone line of the service desk is 4-core, this phone line can be used as a network cable.
3. Telephone lines and network cables transmit signals in different ways.
Telephone lines are generally used to transmit analog signals because the frequency is low, and network cables are generally used to transmit digital signals because the frequency is relatively high.
4. The effect of telephone line and network cable networking is different
The maximum speed of using the telephone line to connect to the Internet is 2M. In addition, the signal loss of the telephone line method is also large, especially if the telephone line has many adapters or the leather wire is damaged, the network speed will generally drop too fast.
Use the network cable to connect to the Internet, and you are "right", and there are no restrictions in this regard. The signal loss of the network cable is small, and it can also ensure a relatively stable speed, so it will indeed reflect a better network speed performance. Therefore, when it comes to networking, phone lines have an absolute disadvantage.
How to connect the telephone line
Generally, the telephone line has 4 cores, but in fact only 2 cores are needed. Unlike the network cable, the telephone line can be connected without any line sequence, as long as the telephone head is made of 2 contact pieces in the middle. It can be connected with a telephone line or a network cable. The telephone line has very little requirements on the cable. The following takes a four-core phone as an example to illustrate the production process!
First, use the wire cutting edge of the wire crimping pliers to cut out the telephone wire that the plan needs to use
Peel off the white protective layer of the phone and let the knife cut through the protective rubber of the phone line
Use the cutting edge of the wire crimping pliers to trim the top of the phone line neatly. It should be noted that the cutting should be inserted in the horizontal direction, otherwise the length of the phone line will affect the normal contact between the phone line and the crystal head.
After cutting, you should press the cables as tightly as possible, and avoid large movements or bending of the network cables, otherwise it may cause unevenness of several groups of already-arranged and cut cables.
