Routing Outside Calls from Different Localities
If the networked systems are separated by a wide geographic distance, usually installers arrange to have each
system connected to its own set of the local service provider’s lines. Local outside calls that users make from their
home systems go out the local service provider’s lines. Long distance calls from one system that are local calls to
another system in the network usually route through the hub and go out over service provider lines connected to
the system where the call would be local.
Again, whenever outside line calling is involved, the line pooling aspect of system-to-system networking comes
into play. Refer to the paragraph titled Understanding the Pooled Lines Network Feature on page 16 for a detailed
discussion of this feature.
