Member Signal
Unacceptable - LCAS
A tributary that is provisioned to be a member of a VCG with LCAS
enabled is determined to be failed as a result of Loss of Multiframe or
its delay is outside the range of differential delay accommodation for
the VCG. (SONET failures, for example AIS, mask the
Member
Signal Unacceptable - LCAS
alarm.) In response to this alarm,
LCAS may remove the tributary from service. If it does, and at least
one tributary remains in service, a
VCG Loss of Partial Capacity
alarm is also generated.
