For 1+1 port protection, both the working and protect SBSs must not be engaged in other
protection; otherwise, an error code will be returned. Likewise for 1:N protection, all the SBSs
should not be involved in other protection at the time of this call with the exception of the protect
SBS which may currently be defined as a protect SBS in a 1:N protection. The same applies to
the UPSR case.
Clearing Port Protection: nbcsFmgtClearProtect
This function clears a 1+1, 1:N port protection or an UPSR association. For 1+1 port protection,
either the working or the protect SBS can be given to clear the protection. In the case of a UPSR,
either one of the SBSs can be given for the clearing. For 1:N port protection, the working SBS or
SBSs (if a group handle containing all working SBSs is supplied) must be given to clear the 1:N
protection. The exception is for the trivial case when N=1 in the 1:N protection, the protect SBS
can also be given to clear the protection.
