MGR I Channel Local Loop Around Test (#228)
This test is destructive.
This test checks the on-board circuitry of the EPN Maintenance circuit pack
associated with the serial link for the terminal connection. This test does not
cause the terminal to become disconnected. However, any data being displayed
on the terminal while the test is running is lost.
Figure 10-62 shows the three serial
interfaces on the EPN Maintenance circuit pack and is meant to clarify that only
the one dealing with the EPN terminal is being tested.
