The telephone line is the entry line of the telephone, which is connected to the telephone before making a call.
Telephone lines are divided into 2 cores and 4 cores.
Conductor materials are divided into three types: copper-clad steel, copper-clad aluminum and all-copper.
All-copper conductors have the best effect.
Gnéithe
1. The common specifications of telephone lines are two-core and four-core, with wire diameters of 0.4 and 0.5, respectively, and 0.8 and 1.0 in some areas.
2. In addition to two cores and four cores, there are four, six, eight and ten cores. In general households, 2 cores are enough if it is a city use mode.
3. If it is used by a company or some PBX, considering the need for broadband use of the telephone, it is recommended to use a 4-core telephone line.
4. If a digital phone is used, it is recommended to use a 6-core telephone line.
