Relay Errors
A relay error is caused when a command fails to reach the Unit to which it has
been sent. A relay error can be caused either by data failing to be passed
between Communications Units connected over a network (see example 1),
or by data being passed from a Communications Unit to a Unit that is not a
Communications Unit (e.g., to a CPU Unit) (see example 2). A relay error may
also occur if the destination node or the next relay node does not exist.
Example 1:
Data fails to be passed between Communications Units due to a routing table
error.
Example 2:
Data fails to be passed from a Communications Unit to the CPU Unit due to
the Communications Unit being offline from servicing.
Example 3:
Destination node or relay node does not exist.
