Radio Failure
The local EtherHaul receives timing information on Eth1 from the network (source) with
quality level PRC (2: ql-prc) and distributes it to all interfaces.
No incoming clock source on the remote EtherHaul as radio link is down.
The remote 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).
