2.7.429 UNEQ-V
An SLMF UNEQ VT alarm indicates that the node is receiving SONET path overhead with Bits 5, 6,
and 7 of the V5 overhead byte all set to zeroes. The source of the problem is not the node raising the
alarm, but the node transmitting the VT signal to it. The V in UNEQ-V indicates that the failure has
occurred at the VT layer.
Warning On the OC-192 card, the laser is on when the card is booted and the safety key is in the on position
(labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the
