Abstract

Disclosed is a process for controlling loopback or wrap tests on a communication link. The process concentrates on V.54 data communication equipment (DCE) loops, but also includes communication controller adapter wrap and link level 2 test. The process provides a technique for determining where line failures exist. It is controlled by the host operator. The process covers point-to-point configurations, multi-point configurations (with and without fan-out capability) and tailed or tandem configurations.
