All trunks or ports on the UDS1 Interface circuit pack must be busied out via the
system technician busyout board command before running the One-Way Span
Test.
The One-Way Span Test has the TN464F UDS1 Interface circuit pack transmit a
framed 3-in-24 test pattern and attempt to receive and verify the pattern. If the
TN464F board receives a framed 3-in-24 test pattern sent from another DEFINITY
G3V3 or test equipment at the far-end of the DS1, it will begin counting bit errors
within the received pattern.
The status of the One-Way Span test will be available in the hardware error log
via error type 3902. Several distinct aux values will be used to give the user
information of the status of the test.
The
list measurements ds1 summary
command will display 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 being sent
cleanly over the span from the far-end, the number of bit errors should be very
low. The
Test Duration
field will show
0
until the test pattern is received from the
far-end. Upon receiving the test pattern, the board will begin calculating the test
duration and number of bit errors. The command will also display 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
).
To terminate the test, enter the
test ds1-loop PCSS end-loopback/span-test
command or the release board command. Using the release board command
will restore all trunks or ports on the TN464F UDS1 Interface circuit pack to the
in-service state.
