One-Way Span Test (#1214)
This test is destructive.
The One-Way Span Test allows one-way span testing to and from remote test
equipment or another Avaya Definity Server. This tested all circuitry and facilities
from the local TN767E DS1 board to the remote test equipment or other Avaya
Definity Servers.
The test is destructive and can only be initiated by a system technician demanded
test ds1-loop UUCSS one-way-span-test-begin command.
Use the busyout board command 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 TN767E DS1 Interface circuit pack transmit a
framed 3-in-24 test pattern and attempt to receive and verify the pattern. If the
TN767E 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 UUCSS end-loopback/span-test
command or the release board command. Using the release board command
will restore all trunks or ports on the TN767E DS1 Interface circuit pack to the
in-service state.
