An SF Path condition is similar to the SF (TRUNK) , on page 390 condition, but it applies to the path (STS)
layer B3 byte of the SONET overhead. It can trigger a protection switch.
The SF-P condition clears when the BER level falls to one-tenth of the threshold level that triggered the
condition. A BER increase is sometimes caused by a physical fiber problem, including a poor fiber connection,
a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice.
