Running the Remote CSU Loopback Test

The remote CSU loopback test is run while a call is in progress. This
test directs the near-end signal through the near-end CSU and sends
it over the telephone lines to the far-end CSU. The signal then loops
through the far-end CSU and back through the telephone lines to the
near-end CSU.
The following Þgure illustrates how the remote CSU test runs.
