Loopback Tests
Overview
Overview
A loopback test is a diagnostic procedure in which a signal is transmitted and returned
to the sending device after passing through all or a portion of a network or circuit. The
returned signal is compared with the transmitted signal in order to evaluate the integrity
of the equipment or transmission path.
DS1 Loopbacks
Note: T1 LEDs flash green during any DS1 loopback.
