Making Outside Calls Across The Network
Routing Outside Calls In The Same Locality
Installers can provision the network with outside lines connected only between the hub and the service provider's
central office. Often this is the orientation used when the networked systems are all at the same site or in the
same geographic location or calling area. Outside calls that users make from both the hub and the nodes route
through the hub and onto the central office lines connected to it.
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 in this
publication for a detailed discussion of this feature.
Typical Example:
Ext. 2000
Area Code
804
System
Node 1 has one DXNET board
in slot 1 providing channels 1-23
that are linked to hub.
Group connecting link channels 1-23 into line group 15.
Enter @ (match any) symbol in ARS restriction table.
Assign @ entry to ARS route table 2.
Define ARS route table 2 to use to use line group 15.
Hub Preparation
Connect node 1 channels to hub channels 1-23.
Connect node 2 channels to hub channels 24-46.
Group CO toll lines in line group 1.
Group CO local lines in line group 2.
Enter 1@ in ARS restriction table.
Assign 1@ entry to ARS route table 2.
Define ARS route table 2 to use line group 1.
Enter @ in ARS restriction table.
Assign @ entry to ARS route table 3.
Define ARS route table 3 to use line group 2.
Local Calls
When extension 2000 dials 9 for ARS and then dials local call 978-2200, node 1 sends the call out over one
of the 23 channels in its line group 15 that is connected to the hub. The hub receives, processes,
and sends the call out over its line group 2 that contains local lines from the CO.
The network handles outside local calls made from extension 3000 in the same way.
Toll Calls
When extension 2000 dials 9 for ARS and then dials toll call 1-540-978-2200, node 1 sends the call out over
one of the 23 channels in its line group 15 that is connected to the hub. The hub receives, processes,
and sends the call out over its line group 1 that contains toll lines from the CO.
The network handles toll calls from extension 3000 in the same way.
6 — Understanding System-To-System Networking Features
Hub has two DXNET boards
in slots 1 and 2 providing
channels 1-23 that are linked
to node 1 and channels 24-46
that are linked to node 2.
