To perform a V.52 test, follow these steps:
1. Activate the local loopback or remote loopback diagnostic.
2. Activate the test pattern. This may be done in one of two
ways:
a. Enter Test Pattern from the System
Diagnostics/Statistics menu and toggle the <Spacebar>
until the desired test pattern appears.
One of two result codes will appear to the right of the
Test Pattern listing:
OK Indicates that the received test pattern is error-free.
BE Indicates that there are errors in the test pattern (to
deliberately insert errors in the pattern, toggle
Error Insertion to ON).
b. Toggle the front panel switch to either PAT or PAT/E (Test
Pattern with Error Injection).
