Inject Single Bit Error Test (#1215)
This test is destructive.
The Inject Single Bit Error test will cause 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 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 loop-back/span
tests (CPE Loopback Jack test, Far CSU Loopback test, One-Way Span test) are
active on a TN767E circuit pack.
All trunks or ports on the DS1 Interface circuit pack must be busied out via 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 loop-back/span test
by one.
To restore the trunks or ports on the TN767E DS1 Interface circuit pact to the
inservice state, execute the release board command.
Table 8-260.
