单词 subrate
释义

subrate

A rate lower than the normal rate. A channel bank typically derives multiple 64-kbps voice-

grade channels from a circuit. If multiple low-speed data applications require less bandwidth, a sufficiently sophisticated time division multiplexer (TDM mux) can subdivide a channel into multiple subrate data channels. See also bandwidth, channel, channel bank, superrate, TDM, and voice grade.
