(VT Path Remote Failure Indication)
The unit is receiving a VT path remote failure
indication. VT-RFI is declared when the
incoming VT path remote defect indication (VT-
RDI, "1" in bit 4 of the VT-Path Overhead byte
(V5) in five contiguous frames) lasts for 2.5 +/-
0.5 seconds.
(VT Path Signal Label Mismatch)
The controller card is detecting a signal label
mismatch in the VT path. A received signal label
is mismatched if it does not equal the locally
provisioned value or the value "equipped non-
specific".
(VT Path Unequipped)
The controller card detects that the VT path is
unequipped. The VT path is not provisioned.
Byte V5 of the STS path overhead is set to zero.
