2042 FAIL This is the main purpose of the test. The comparison of the
data sent with the data received indicates a loss of integrity on
the communications path.
1. The trunk should be taken out-of-service and the quality of
the DS1 line should be investigated. The investigation
should include an in-depth analysis of the DS1 facility
including the transmission facility and any external
equipment such as DACs, CSUs, etc. If test isdn-testcall
is used, then the investigation should include getting the
bit and block error rates by invoking status isdn-testcall.
PASS The call worked. A test pattern was sent and received
properly; the communications path is OK if the synchronous
test call command was issued. If test isdn-testcall was used,
a PASS indicates that the test call was established. A status
isdn-testcall must be invoked to query the bit and block error
rates to determine if the test call passed. An in-depth analysis
of the DS1 facility including the transmission facility and any
external equipment such as DACs, CSUs, etc., should take
place if the bit and block error rates are not acceptable.
