Chapter 2 Alarm Troubleshooting
An SLMF UNEQ low-order path alarm alarm indicates that the node is receiving SDH 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 VC signal to it. The V in SLMF UNEQ low-order path
alarm indicates that the failure has occurred at the VC layer.
Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Do not stare into the beam directly with optical instruments. Viewing the laser output with certain
optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of
100 mm could pose an eye hazard. Statement 1056
