1.7.203 SF-L

An SF Line condition applies to the line layer B2 overhead byte of the SONET signal. It can trigger a
protection switch. The SF-L 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.
The condition is superseded by higher-priority alarms such as
(OCN).

1.7.204 SF-P

An SF Path condition is similar to an
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.
