Can the hotel telephone line be used as a network cable?

Telephone lines are different from network lines. Network cable can't be replaced by telephone line, because it needs 8 cores, and telephone line has 4 or 2 cores, so the transmission bandwidth is not enough, but network cable can be used as telephone line. In addition, the transmission signals and technologies used by the two are also different. Details are as follows:

1, telephone lines are parallel lines, network cables are generally twisted pairs, telephone lines are generally two cores, and network cables are generally eight cores. Telephone lines are generally used to transmit analog signals, because the frequency is low, and network lines are generally used to transmit digital signals, because the frequency is relatively high, and twisted pair is used, so the distance cannot be too far; Therefore, the former can be replaced by the latter, and vice versa;

2. They are also different in transmission and working principle. Telephone lines transmit analog signals, while network cables are used to connect computers and cats and transmit digital signals. At present, fttp transmits network optical signals through optical fibers, and converts optical signals into electrical signals through optical cats, which can be recognized by network cards and routers.

3. Telephone line access is also called ADSL broadband, which uses ADSL technology to provide asymmetric uplink and downlink bandwidth, so it is called asymmetric digital subscriber line. Through ADSL and telephone line, the digital signal of the computer is modulated into an analog line number, and then the analog signal is demodulated into a digital signal at the opposite end, which can provide voice and data services at the same time.
