Introduction
The MiVoice Office 250 is capable of connecting with other Mitel platforms to form a network that
supports many call processing features. This networking capability can be implemented using
point-to-point T1/E1 PRI circuits, or it can be implemented using IP networking.
To the user, the network appears as though it is one integrated system. With few exceptions, users
can perform all of the functions across the network that they can perform within a stand-alone
telephone system.
In this appendix, all references to a “network” indicate two or more MiVoice Office 250 systems
connected by a network span. Each system in a network is called a “node.” There can be up to 99
nodes per network with a combined total of up to 40,000 devices on the nodes. See the
Specifications and Product Description chapters for additional information on capacities. See
Network IP Topology for information on network topology, including firewalls and NAT.
The system supports several private networking configurations. Between any two networked
systems, there can be any combination of T1/PRI or E1/PRI modules.
The Networking Wizard allows you to quickly configure the system for IP Networking or T1/E1 PRI
Networking. For additional information, refer to the
MiVoice Office 250 Features and Programming

.
• T1/PRI or E1/PRI Connections : T1M or T1M-2 modules configured this way are used for
connecting system nodes in a network. Each network span requires two T1M or T1M-2 modules,
one for each end of the span. See page 395 for more details.
• IP Networking : DB Programming provides private networking using an IP network. See
page 397 for more details. See the Specifications chapter for information on IP resource
capacities.
