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 Loop-Back Jack test, Far CSU Loopback test,
One-Way Span test) are active on a UDS1-BD circuit pack.
Every trunk or port 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.
