work 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.

MANUAL VERSION 11.0 – May 2008
With system software version 7.0 and later you can connect two or more Inter-Tel
In this manual all references to a "network" mean two or more Inter-Tel systems con-
There can be up to 99 nodes per network with a combined total of up to 40,000 devices
1792 devices on each node
25,000 entries in the database for off-node devices on each node
32 system serial ports on each node
The system supports several private networking configurations. Between any two end-
T1 Connections: Are used for connecting system nodes in a network. Each network
span requires two T1/PRI or T1/E1/PRI cards, one for each end of the span. See
page A-7 for more details.
IP Networking Module (3200N): Is basically an extension of ISDN designs. It utilizes
one channel of a primary rate interface (PRI) to transfer data in the form of high-level
data link control (HDLC) packets containing all of the information necessary to process
calls on the remaining channels. The Networking Module networking is derived from
the Q.SIG standard (an international signaling standard for PBX-based private net-
works) and modified to accommodate the proprietary messages required by Telephone
System networking. For more details, refer to the Inter-Tel IP Networking Module Man-
ual (part no. 730.8001).
IP Networking using an IP Resource Card (IPRC): System Versions 7.0 and later
allow an IPRC to be programmed in the Database (DB) Programming to provide private
networking using an IP network. See
