System Network Capacities
8. SYSTEM NETWORK CAPACITIES
8.1 With phone system software versions 5.0 and later, you can connect two or more Inter-
Tel systems, including ATM systems, to form a network that provides an interface between the
systems. To the user, the network appears as though it is one integrated system. With few
exceptions, the user can perform all of the functions across the network that he can within a
single phone system.
NOTE: If using v6.0 or later in a networked system, all other nodes must be running version
5.2F9 (or later) or 5.349 (or later).
8.2 In this manual, all references to a “phone network” mean two or more phone systems
connected by a network span. Each phone system in a network is called a “node.”
8.3 The maximum capacities of the network are listed in the following table.
* The maximum number of stations and trunks that can be installed is limited by the number of voice
channels and/or system memory resources available.
A. 99 NODES SUPPORT
8.4 V10.0 or later software for the U.S., Europe, and Mexico allows the phone network to
expand to 99 nodes. Nodes can transparently inter-connect to 98 other systems via T1/E1 PRI
networking and IP networking.
8.5 The increased network capacity does not affect endpoint user features. Endpoint users
can still dial an extension of a remote user, and the system transparently routes the call
throughout the network. From an administrative perspective, you must consider the following
as the node capacity increases:
• Database Management: As it is done today, you must log in to individual systems to
configure the systems. You must plan for supporting a 99-node network by devising a
numbering plan for each node. You should be aware that the creation of new devices
automatically causes the system to export extensions to the network. The use of export/
import may take longer if you attempt to export/import with all 98 remote nodes.
• Off-Node Device Limit: As more endpoints are added to nodes within the network,
each system broadcasts new endpoint extensions throughout the network. For very large
networks, this may create a problem for the Call Processing Card (CPC) systems
because there is a limited amount of dynamic memory on the CPCs. You must be aware
of the amount of available dynamic heap on the CPCs as the network grows. Even if
specific off-node extensions are removed from a node, a DB Programming export per-
formed by a remote node administrator may cause the off-node extensions to reappear.
Therefore, it is important to apply the same changes to all the nodes for changes to
properly take effect. If you want to delete an off-node device, you need to delete it on
the remote node as well.
