Model No. Running Head DS0-DP Card Specifications DS0-DP Card
4. At the local end (where the incoming data loss was first observed), use the loopback
functions of the DS0-DP card to test the affected port. These tests are accessible from
the DS0-DP Card Main Screen, as previously described in this chapter. They allow you
to test the circuit path in segments and thereby quickly pinpoint the problem.
5. If necessary, also perform loopbacks and send test signals to the affected circuit from
the other end. In addition, you can perform end-to-end tests using a suitable data test
set at one or both ends of the circuit in conjunction with the loopback functions of the
DS0-DP card at either end.
6. If the DS0-DP card is determined to be faulty, replace it and return the faulty unit for
repair to the location specified by your distributor.
