Digital Port Sanity Test (#565)
This test verifies that the port circuitry involved in the digital trunk testing on the
Maintenance/Test Digital Port is functioning properly. This circuitry is common to
both Maintenance/Test Digital Ports on the Maintenance/Test circuit pack.
Therefore, this test is only run for Port 2. The test aborts when run on Port 3, as
described in Table 10-299
.
This test operates by connecting the two Maintenance/Test Digital Ports on the
TDM Bus so that they talk and listen to each other. Then four self-tests are
attempted: (a) sending data from Port 2 to Port 3 in asynchronous mode; (b)
sending data from Port 3 to Port 2 in asynchronous mode; (c) sending data from
Port 2 to Port 3 in synchronous mode; and (d) sending data from Port 3 to Port 2
in synchronous mode. The test passes if all four of these self-tests are
successful. The test stops as soon as any one of these self-tests fails.
This test aborts if an ISDN Test Call is in progress on either Maintenance/Test
Digital Port when the test is requested, or if an ISDN Test Call is initiated while the
Digital Port Sanity Test is in progress.

Result Description/ Recommendation
Any ABORT This test should never abort.
Any FAIL This test should never fail.
1. Retry the command at one-minute intervals a maximum of five
times.
2. If the test continues to fail, escalate the problem.
PASS The message to clear the Maintenance/Test circuit pack’s counter for
Background Maintenance Failures has been sent.
