2.7.171 LP-PLM
A Payload Label Mismatch Path alarm indicates that signal does not match its label. The condition is
indicated by an invalid C2 byte value in the SDH path overhead.
This alarm can occur on a 15310-MA-CTX, E1-21/DS3-E3-3, or E1-63/DS3-E3-3 card when it expects
a E1 signal but receives a DS-3 signal. The DS-3 signal C2 byte value is 4, so this causes a label
mismatch and a LP-PLM alarm.
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Warning
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
Use of controls, adjustments, or performing procedures other than those specified could result in
