This standard applies to 1.2/4.4mm coaxial integrated communication cables. The coaxial pair is used for 22MHz and below analog trunk communication system or 34Mbit/s and below digital communication system. High-frequency quadruples and high-frequency twisted pairs are used in 156kHz and below analog communication systems. Low frequency quads and low frequency twisted pairs are used in audio communication systems.
