Data
Stream Clocking
Common in T1 links, data stream clocking occurs when separate
clock signals are not transmitted within the network. Instead, devices
must extract the clock signal from the data stream. As bits are transmitted
across the network, each bit has a time slot of 648 nanoseconds.
Within a time slot, pulses are transmitted with alternating voltage
peaks and drops. The receiving device uses the period of alternating
voltages to determine the clock rate for the data stream.
