Multi-Site Networking
Multi-Site Networking is a network of three or more Aspire systems connected by either ISDN or IP.
The conÞguration for three or more sites is the same as for two sites, refer to ISDN Networking
(page 12) or IP Networking (page 16) for details of setting up the Aspire systems. Please refer to
the following list before installing Multi-Site Networking.
● All systems must have NTCPU software version V2.5x or later.
● It is recommended that all systems in the network have compatible levels of software
installed. Refer to Networking Software Levels (page 4).
● A Feature Upgrade PAL chip (P/N 0891039) is required for the Basic NTCPU or an Enhanced
NTCPU (P/N 0891038) can be used to enable Networking.
● A network can combine both ISDN and IP Networking within the same network as long as
there is direct connection between each system. Refer to Networking Using Mixed PCBs
(PRI, BRI or VoIP) (page 4) for additional information.
● All systems within the network must have a direct connection to all other systems in the net-
work. This makes IP Networking the more practical type for Multi-Site Networks - only one
VOIPU PCB is required in a system cabinet regardless of the number of networked systems,
where PRI or BRI would require one PCB be installed in a system cabinet for each networked
system.
● VOIPU resources will be used at each system when a call is transferred. For example, a call
that originates from System A and calls System B, is held and transferred to System C, will
use VOIPU resources at all three systems.
The same also applies for ISDN Networking - an ISDN channel will be used from System A
to B and also from System B to C.
