UDS1-BD (UDS1 Interface Circuit Pack)
Issue 5 October 2002

555-233-119
Inject Single Bit Error Test (#1215). This test is destructive.
The Inject Single Bit Error Test causes a single bit error to be sent within an active
framed 3-in-24 test pattern.
The test is highly destructive and can only be initiated by a system technician
demanded test ds1-loop UUCSS inject-single-bit-error command. An attempt
to use this command will be rejected if none of the three long-duration DS1
loopback/span tests (CPE Loopback Jack Test, Far CSU Loopback Test,
One-Way Span Test) are active on a UDS1-BD circuit pack.
All trunks or ports on the UDS1 Interface circuit pack must be busied out using the
system technician busyout board command before running the Inject Single Bit
Error Test.
The list measurements ds1 summary command displays the number of bit
errors detected (
Loopback/Span Test Bit-Error Count
field). Injecting this
single bit error should increment the bit error count of the loopback/span test by
one.

Result Description/ Recommendation
ABORT Internal system error
1. Retry the test ds1-loop UUCSS inject-single-bit-error command at
1-minute intervals a maximum of 5 times.
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.
