Installing And Using System-To-System Networking
Introducing System-To-System Networking
System-to-system networking connects several DXP, DXP Plus, or FX Series systems together in an arrangement
that allows unified communications through the systems.
A signalling protocol based on Integrated Services Digital Network (ISDN) controls the network interface
between the systems. The interfacing hardware associated with this communications scheme is designated with
the product code DXNET for DXP and DXP Plus systems and FXNET for FX Series systems. The network
interface consists of the following hardware:
•
T1 line board equipped with a primary rate interface (PRI) circuit card,
•
special purpose firmware integrated circuit chip
In addition to the network interface board required at every system in the network, the common equipment at
each node system requires a synchronization card (DXOPT–SYN). (The hub system does not require a
DXOPT–SYN card to perform on-site network functions.)
NOTE: If you also have the hub connected to the service provider through regular T1 boards for normal
outbound call traffic, you will need to install a DXOPT–SYN card in the hub system for that application.
The communications network consists of one system acting as the hub and the remaining systems serving as
nodes. The network allows up to six nodes in addition to the serving hub making a total of seven systems
combined into the network. The hub can be either DXP, DXP Plus, or FX Series common equipment; however, a
DXP Plus provides best results due to the possible heavy network traffic through the hub. The nodes, on the other
hand, can be DXP, DXP Plus, or FX Series common equipment.
The network can be an intra-network joining several systems at a common site or an inter-network joining several
systems across a geographic area. When a service provider supplies the communication connections between the
hub and the nodes, these connections must be T1.5 dedicated access lines for network use.
NOTE: With T1 service, there is always confusion about what the term line denotes. Since there are actually
multiple lines in one T1 line, the more encompassing term for this connection is span, or in the case of this
networking document, link. A span or link usually refers to the single 4-wire T1 connection from the
service provider. A span or link could consist of as many as 23 to 30 lines depending upon the type of T1
service. To further define the term line when used in conjunction with T1 service, this networking
document uses the term channel to refer to the individual lines in a link.

  • Page 4 IMI89–280 Installing And Using System-To-System Networking Understanding System-To-System Networking Features Currently, system-to-system networking provides the following joint activities with the hub and all connecting nodes: • unified intercom dialing with name display, • outside calling across the network, • centralized voice mail. Performing Unified Intercom Dialing A user at a station connected at one node can make an intercom call to any station that is connected to the local node, to the hub, or to any other node.
