Abstract
A loopback enabled by an instruction and address code pair transmitted with the regular data stream affords a simplified fault location scheme for a T1 repeater span. By selecting unique addresses for each repeater using a predetermined frame sequence and by testing for logic error density, erroneous enablement is avoided.
