Remote Loopback with Self-Test

The remote loopback with self-test can only be initiated from the
front panel interface. This test uses an internal test data generator
and error detector to send data to the remote station and to check
the return data for errors. The green DATA LED flashes off to
indicate errors are detected. You must be on a data call to run a
remote loopback with self-test.
You should conduct this test when the local DTE can neither send
nor check the returned data for errors. You cannot send or receive
data during this test.
The following procedure contains step-by-step instructions for
initiating a remote loopback with self-test from the front panel
interface. Refer to the Remote Loopback with Self-Test section of
Chapter 6, ''Test Descriptions'' for details of this test.
