normal. This alarm is raised on the 8K clock if that variation discontinues. The BPV alarm is demoted
by an LOF or LOS against the BITS clock.
This alarm is not raised on the TCC2 card.

The Carrier Loss alarm is raised on CE-Series cards in Mapper mode when the port is In-Service (IS) state
and if there is no carrier signal. Circuit need not be present to raise the alarm. In releases prior to 6.01 the
Carrier Loss alarm is raised on CE-100T-8 cards in Mapper mode when there is a circuit failure due to link
integrity. It does not get raised when a user simply puts the port in the In-Service and Normal (IS-NR) service
state.
