2.5 Notes on System Configuration
In an IP system using subnets to differentiate telephony areas, each subnet
must have its own SVP Server as well as access points. This is not
considered a multiple SVP Server environment since the SVP Servers are
separated by the subnet architecture. Multiple SVP Server environments
are those which have more than one SVP Server in the same subnet in
order to accommodate a high volume of wireless telephony traffic.
Wireless Telephones cannot roam between subnets. Any call in progress
will be dropped when the user moves out of range. In order to resume
functionality in the new subnet area, the user must power cycle the
Wireless Telephone. Once the Wireless Telephone achieves
communication within the new subnet, normal functionality will return.
Subnets are not recommended in NetLink Telephony Gateway
environments.
IP multicast addresses are used by the NetLink i640 Wireless Telephone
system. This requires that multicasting be enabled on the subnet used for
the NetLink Wireless Telephones, SVP Server, and Telephony Gateways.
Routers are typically configured with filters to prevent multicast traffic
from flowing outside of specific domains. The wireless LAN can be
placed on a separate VLAN or subnet to reduce the effects of broadcast
and multicast traffic from devices in other network segments.
