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 c 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 c 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

d Error Insertion to ON).

b.Toggle the front panel switch to either PAT or PAT/E (Test Pattern with Error Injection).
