Transmission Signal Quality Testing
Measuring Bit Error Rate
The bit error rate (BER) test is one of the best ways to measure the
quality of a SONET transmission link. You can use the CTS 710 to
make a BER test on a two-way link that is connected in a loop-back
configuration. If this is a test you perform often, save it as a pass/fail
test for easy recall.
1. Connect the CTS 710 to a network as shown in Figure 3–2.
