External Clock Failure

If the terminal Clock Source is set to Network, the terminal will automatically clock from the nominated
primary clock source if that clock source is available.
If the nominated primary clock source is not available, the terminal will clock from the nominated
secondary clock source if that clock source is available.
If the nominated secondary clock source is not available, the terminal will clock from the internal clock
source.
When a nominated clock source becomes available (primary or secondary), the terminal will then clock
from that clock source.
