WAN Status LED is yellow. The link is faulty
(far-end system has
detected an abnormal
incoming T1 signal).
Perform the BERT test (and other steps above from the far
end) in conjunction with a T1 line loopback at the Tasman
Networks router.
WAN Status LED blinks
green or yellow. The link is not properly
configured at one or both
ends or it is operating
marginally. 1 If frame errors are present, look for a configuration
mismatch between the Tasman Networks system and
the far-end system.
2 If CRC-6 errors or BPVs are present, check the Line
Build Out (LBO) configuration settings at both ends.
System cannot lock onto a
BERT pattern from the far
end. The BERT test has
failed. Try using another BERT pattern. If the problem continues,
call your WAN service provider.
BERT error rate exceeds 1%
of transmitted bits. The link is faulty or
deteriorating. 1 If an all-ones or all-zeros test is in progress, check the
Line Build Out (LBO) configuration.
2 If a QRW test is in progress, check for the same link
configuration at the far end.
