UDS1-BD (UDS1 Interface Circuit Pack)
Issue 4 May 2002
10-1925 555-233-123
The One-Way Span Test has the UDS1 Interface circuit pack transmit a framed
3-in-24 test pattern and attempt to receive and verify the pattern. If the UDS1-BD
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 begins counting bit errors within the
received pattern.
The status of the One-Way Span test is available in the hardware error log via
Error Type 3902. Several distinct Aux values 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 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 test ds1-loop UUCSS end-loopback/span-test or
release board. Using release board restores all trunks or ports on the UDS1
Interface circuit pack to the in-service state.

Error

Te s t
Result Description/Recommendation
ABORT Internal system error
1. Retry the test ds1-loop UUCSS one-way-span-test-begin
command at 1-minute intervals a maximum of 5 times.
1005 ABORT One-Way Span Test cannot be executed in the current
configuration. To run this, the TN464F or later suffix UDS1 must
be administered for 24-channel operation. The “Bit Rate” field on
the DS1 circuit pack administration form must be set to “1.544”
for 24-channel operation.
1015 ABORT Ports on the UDS1 Interface circuit pack have not been busied
out to out-of-service.
1. Enter the busyout board UUCSS command to put all
trunks or ports of the UDS1 Interface circuit pack into the
out-of-service state.
2. Retry the command.
