A frame is comprised of a single byte from each of the T1's timeslots; there are 24 timeslots on a single T1
circuit. Framing bits are used to separate the frames and indicate the order of information arriving at the
receiving equipment. D4 and ESF are two methods of collecting and organizing frames over the circuit.
