Circuit switching:  The temporary connection of two or more communications channels using a fixed, non-shareable path through the
network.  Users have full use of the circuit until the connection is terminated.
Clear Channel:   A transmission path where the full bandwidth is used (i.e., no bandwidth needed for signaling, carrier framing or control
bits).  A 64K bps digital circuit usually has 8K bps used for signaling.  ISDN has two 64K bps circuits, and a 16K bps packet service...

Digital Loopback:  A technique used for testing the circuitry of a communications device.  Can be initiated locally, or remotely (via a
telecommunications device).  The tested device decodes and encodes a  received test message, then echoes the message back.  The results

Extended Super Frame (ESF):  One of two popular formats for framing bits on a T1 line.  ESF framing has a 24-frame super-frame, where
robbed bit signaling is inserted in the LSB (bit 8 of the DS-0 byte) of frames 6, 12, 18 and 24.  ESF has more T1 error measurement capabili-
ties than D4 framing.  ESF and B8ZS are typically both offered to provide clear channel service.
