Private Networking
391
Figure 4
illustrates an example of private networking using T1M or T1M-2 modules and IP resources
in the MiVoice Office 250.
Figure 4 on
page 391
shows the networking types: IP and T1/PRI connections. Each type can
communicate directly with another node that uses the same connection type. For example:
• Phoenix and Austin can speak directly to each other through the IP Resource Application and
the IP network.
• Austin and Dallas can speak directly to each other through the T1 connection (PRI).
• San Diego and Dallas can speak directly to each other through the IP Resource application and
the IP Network.
Nodes with different networking types can also communicate with each other, but not directly. To
communicate with a dissimilar node, the call must be routed through a node with the same networking
type. For example, if Phoenix needs to call Dallas, the call must first go through Austin. For Austin
to speak with San Diego, the call must first go through Dallas. With proper planning and design of
call routing patterns, an IP private network can be optimized such that no more than one hop is
required between dissimilar nodes.

IMPORTANT
You must have sufficient PRI licenses, part number 840.0227, to configure the
necessary ports on the T1M or T1M-2 module for PRI use.
