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 local central office lines. Local outside calls that users make from their home
systems go out the local central office 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 central office lines that are 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 that is located later in
this publication for a detailed discussion of this feature.
Typical Example:
Node 1 has one DXNET board
in slot 1 providing channels 1-23
that are linked to hub.
Node 1 has one connection to local
CO for both toll and local calls.
