System Traps
VT-RFI (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-SLM (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-UEQ (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.
Trap If enabled, the unit issues a trap when...
