Line Failure
No incoming clock source on the local EtherHaul as line link is down.
The local EtherHaul switches to holdover mode (internal clock) while maintaining the
PRC clock accuracy it received previously and distributing it with its own quality level
(11: ql-eec1).
The remote EtherHaul receives and is locked on its Eth0 source and distributes timing
information from this source to its interfaces.
