ORE FROM OUR ELEPHONE
(NBX 100 and SuperStack 3 NBX) On these systems, you can dial calls
between sites that are separated geographically but that are linked by a
Wide Area Network (WAN) connection. Typical configurations are
described in the next sections.
In the sample network shown in
telephone extensions. Whenever you make a call to an extension not
located at your own site, your NBX system sets up a connection to the
appropriate site.
In this example, to call a user in Dallas, a user in Chicago dials a Dallas
extension (3000 through 3999). The dial plan on the Chicago NBX system
sets up the necessary connection to the Dallas NBX system and then to
the extension at that site.

Your administrator also can configure your telephone system to use site
codes for dialing remote offices. Each site may have overlapping
telephone extensions. In this example, you dial a site code first, followed
by the extension at the site. Your administrator chooses the site codes for
your system.
For example, as shown in
Chicago dials the site code 62 and then the appropriate extension (1000
through 3999). To reach a user in Dallas, a user in Chicago dials 63 and
then the appropriate extension (1000 through 3999). The site code
prevents conflicts between the remote extension number and a
duplicated extension number at the local site (Chicago).
