Maintenance Demand Tests
The One-Way Span test allows 1-way span testing to and from remote test equipment or
another Communication Manager solution. This tests all circuitry and facilities from the local
DS1 board to the remote test equipment or other Communication Manager solution.
The test is destructive and can only be initiated by entering the command
test ds1-loop location one-way-span-test-begin.
Enter busyout board to busy out all trunks or ports on the DS1 Interface circuit pack before
running the One-Way Span test.
The One-Way Span test has the DS1 Interface circuit pack transmit a framed 3-in-24 test
pattern and attempts to receive and verify the pattern. If the DS1 board receives a framed
3-in-24 test pattern sent from another Communication Manager system or test equipment at the
far end of the DS1, it begins counting bit errors within the received pattern.
Note:
Note: If a DS1 circuit pack and a DS1 Interface media module are connected, the test
will fail because the media module does not frame-align its test pattern.
The status of the One-Way Span test appears in the error log as Error Type 3902. Several aux
values give information on the status of the test.
Enter list measurements ds1 summary to see the length of time the test has been
running (Test Duration field) and number of bit errors detected (Loopback/Span Test
Bit-Error Count field). If the test pattern is sent cleanly over the span from the far end, the
number of bit errors should be very low. The Test Duration field is 0 until the test pattern is
received from the far end. Upon receiving the test pattern, the board begins calculating the test
duration and number of bit errors. The command also shows the type of loopback/span test
executing (Test field), the type of pattern generated for the loopback/span test (Pattern field),
and whether the pattern (i.e., 3-in-24 Pattern) is synchronized (Synchronized field).
Enter test ds1-loop location end-loopback/span-test or release board to end
the test. Enter release board to restore all trunks or ports on the DS1 Interface circuit pack
to the in-service state
This test is run on the DS1-BD (DS1 Interface Circuit Pack) and UDS1-BD (UDS1 Interface
Circuit Pack) maintenance objects.
