29. Without a spare loopback plugs are handy for diagnosis Note that internal loopback facilities of the Loop E does not include the interface circuitry Thus a set of plugs one for each of the interfaces line and DTE are needed for complete tests These plugs are wired such that signals from the Loop E are loopback by hard wire back to the receive pin of the same plug Replace the line connector with a loopback plug Observe if the line is in sync If not then Loop E has failed Then perform a PRBS test towards the line If this fails then Loop E has failed For the DTE ports a loopback plug must be used in concert with a far end Loop E if such a terminal is available then a PRBS test will determine if that DTE port is at fault Note that if a far end terminal is available the first test should be a local line loopback to see if the line is good If the local DTE has diagnostic capabilities then a loopback plug towards the DTE would help determine if the line to the DTE is good This can further help isolate the problem If tests with loopback plugs all pass then the problem is probably elsewhere 4 5 Chapter 4 Maintenance 4 6 4 Using Bert Test Set If a BERT bit error rate test set is a available such as the Fireberd 6000 then a comprehensive suite of test are available to examine the health of the Loop E With a BERT each of the ports of the Loop E can be tested individually The user must configure the BERT in the exact w
