Testing and troubleshooting
Use DO commands to perform testing and troubleshooting tasks: measure bit-error rate test
(BERT), measure performance with a remote loopback test, and perform remote management
tasks. Use the DO commands discussed in the following sections when you need to analyze the
performance of a MAX unit, the network, or remote units.
Using bit-error tests
A bit-error rate (BER) is the ratio of error bits to the total number of bits transmitted. A MAX
unit can perform a bit-error rate test (BERT) by sending a known pattern of bits and counting
