Test Results
Standard frame synchronization algorithms require errors in two or more consecutive
frame alignment words in order to declare loss of frame synchronization. Since the
number of errors is limited to one, frame loss will not be declared.
The following results were obtained using the setup in
operation:
• Jitter added to the input signal. The input T1 and E1 input signals were modulated with
• Maximum number of errors per switching event: 1 error
• Probability of an error during a switching event: 50%
• No frame synchronization loss
sinusoidal jitter. The tests were performed at the jitter frequency/amplitude points listed
in
