MTP Analog Loop Around Test (#103)
This test is a nondestructive test. The test does a loop around by using the MTP
INADS channel. Test data is sent through the modem out toward the INADS trunk.
The data is looped around before the actual trunk, and it comes back into the
on-board modem. The data is then verified for integrity. The internal modem is
tested when the internal modem is selected. The external modem is tested when
the external modem is selected.
When an external modem is administered in place of the internal modem, the test
loops data in the MTP DUART ahead of the connection to the external modem.
This test also causes the MTP DUART to verify that Clear-To-Send (CTS) is
being supplied by the modem.
NOTE:
The test does not send any data onto the INADS trunk. However, to pass,
the test does require the trunk to be present
