Why does the HYA communication cable have so many pairs of lines? What's the effect of each pair of wires?!
Large logarithmic cable, each pair of lines can run only one carrier, the most common is all the way voice or ADSL.
HYA communication cable: copper core, solid polyolefin insulation, moisture retaining layer, polyethylene sheath, local communication cableThe most widely used HYA communication cable in the www.hxldx now is 0.4mm and 0.5mm.The 100 line is to connect 100 phones, each pair of wires can be connected to a telephone line, generally 100 to 2 of a backup line 50 on line 1, how to back up the line, if in use of 1 lines can be replaced directly to the backup line. This will enable normal communication.
With the popularity of optical fiber and cable, the large logarithmic telephone cable will be eliminated.
