Strictly speaking, a measurement of transmission speed
equal to the number of signal level changes per second. In
practice, often used synonymously with bit rate and bps .
(Bearer-channel) 64- or 56-kbps channel that carries a
variety of digital information streams, such as voice at
64 kbps, data at up to 64 kbps, wideband voice encoded at
64 kbps, and voice at less than 64 kbps, alone or
combined .
See BRI .
See B-channel .
One of three modes of system operation, in which the
