IP Networking
145
When used in a cluster environment, the network ID must equal the Cluster Routing digits.
When not in a cluster environment, the network ID must equal the Node ID.
Automatic Route Selection
When Automatic Route Selection (ARS) involves TDM connections that include switched
DPNSS or X-Net, restrictions apply to the range of IP addresses used on the ICP RTC. Each
ICP controller requires an IP address to uniquely identify it and each uses a fixed effective
subnet mask of 255.255.255.192. IP addresses between units must be different than the
effective mask. Examples are shown in Table 42 below:
Further details on installation can be found in the Technician's Handbook and in the System
Administration Tool Help for MiVoice Business.
Number Planning and Restrictions
The length of number plans for clustering and resiliency should be consistent among all units
to prevent confusion in routing. Plan the location of systems and number assignments before
installation.
Clustering is the recommended configuration for larger systems. Clustering is required for
Resiliency.
Use MiVoice Enterprise Manager, to plan and control operation of the different units. This is
also required for Resiliency.
Further details can be found in the Clustering and Resiliency documentation.
WARNING:IN A NETWORK CONSISTING OF A CLUSTER OF ICPS, ROUTE
OPTIMIZATION SHOULD NOT BE ENABLED FOR ICP UNITS PRIOR TO
RELEASE 4.2. ALSO, WITH ROUTE OPTIMIZATION ENABLED, IT IS NOT
RECOMMENDED TO HAVE A NETWORK CONSISTING OF ICPS WITH MIXED
SOFTWARE RELEASES (4.0, 4.1 AND 5.0) AS CALLS MAY BE DROPPED.
Table 42: Examples of IP address
Assignment for Use in Automatic Route Selection
ICP 1 IP address ICP 2 IP address Acceptable?
192.168.1.2 192.168.1.66 Yes (different subnet)
192.168.1.2 192.168.1.130 Yes (different subnet)
192.168.1.2 192.168.1.127 No (broadcast address on second subnet)
192.168.1.2 192.168.1.62 No (within same subnet mask range)
Note: Certain features such as Group and Trunk Hunting are limited to a single controller
and do not span the network. Plan to have common groups or departments focused
onto a single unit.
