Isolating Problems Using Loopback Data Tests

Loop-Around Data Test

Arrangement

The 8400B Plus Data Module Loop-Around Data Test Arrangement provides a simple mechanism that can be installed on a DEFINITY Communications System, to isolate Digital Communications Protocol (DCP) data problems. In the Loop-Around Data Test Arrangement one or more 8400B Plus Data Modules are set up for auto-answer, and have the received data lead looped around to the transmit data lead on the data module’s EIA interface. A user can then dial up, and see whether data typed in at the local station is echoed back. A typical use for this would be a user who calls the Help Desk with the complaint that he/she cannot access a local host. The user can be instructed to utilize the Loop-Around Data Test Arrangement (see Figure D-6).
