E-carrier system promulgated by the {ITU} and used outside of North America and Japan. The basic unit of the E-carrier system is the {DS0}, which has a transmission rate of 64 Kbps, and is commonly used for one {voice circuit}. The {E1} format consists of 32 DS0 channels, for a total capacity of 2.048 Mbps. {E2}, {E3}, {E4}, and {E5} circuits carry multiple E1 channels multiplexed, resulting in transmission rates of up to 565.148 Mbps. The E-carrier system is similar to, and compatible with, the {T-carrier system} used in North America, but has higher capacity since it uses {out-of-band signaling} in contrast to the {in-band signaling} or {bit-robbing} used in the T-system.
