It is advisable to have compatible levels of Aspire software installed on all systems within the Net-
work. Although the basic Networking operation will operate correctly, there could be problems
with features that are only available from a given level of software.
Aspire Software V2.01
● Two Aspire systems can be installed in the network.
● Networked Park Hold should not be used.
Aspire Software V2.5x
● More than two Aspire systems can be installed in the network.
The networked systems can use a combination of PRI, BRI or VoIP PCBs. Refer to
Networking Using Mixed PCBs (PRI, BRI or VoIP) (page 4).
● For Networks with more than 10 systems.
● Networked Park Hold should not be used.
The Aspire system software version 2.5x allows you to install up to 10 Aspires within the network.
With software prior to version 2.5x, you should not install more than two systems in a network.
All systems must have either the 64-port NTCPU with Feature Upgrade PAL (P/N 0891002 and
0891039) or the Enhanced NTCPU (P/N 0891038) installed and version 2.5x software or later is
recommended.
Refer to Multi-Site Networking in this manual for information on installing more than two Aspire
systems in a network.
A network can consist of a combination of VOIPU, PRI and BRI PCBs. In order to create a network
using mixed media, you must keep a direct connection between the systems. IP resources will
receive priority over ISDN resources in a mixed media network. Refer to the following mixed
media examples:
Networking via IP and ISDN (as a backup for extra resources)
This connection will work because each system is connected via the VOIPU and PRI/
BRI PCBs. The IP resources will get priority. The PRI resources will be selected when the
IP resources are in use or unavailable.
