2.7Notes on System Configuration

In an IP system using subnets to differentiate telephony areas, each subnet must have its own APs. Each subnet may require an SVP Server to maintain voice quality, but this depends on traffic volume and router capacity.

Multiple SVP Server environments are those which have more than one SVP Server. A master SVP Server must be identified in a multiple-SVP Server environment.

SVP Server models may not be combined within one subnet. More than one SVP Server model type may be used within a facility if installed on different subnets.

Wireless telephones cannot roam with uninterrupted service between subnets unless specific LAN components are present. Certain AP/Ethernet switch combinations establish a layer-2 tunnel across subnets that enables the handsets to roam. Without this capability, any call in progress will be dropped when the user moves out of range and the handset must be power cycled in order to resume functionality in the new subnet area.

Please see Deploying Enterprise-GradeWi-Fi Telephony for detailed configuration information when installing multiple SVP Server models across several different subnets.

IP multicast addresses are used when NetLink i640 and 8030 Wireless

Telephones are installed. 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.

The NetLink SVP Server requires a Cat. 5 cable connection between its

network port and the Ethernet switch. The NetLink SVP Server auto- negotiates to the type of port on the Ethernet switch and supports 10Base- T, 100Base-T, full-duplex and half-duplex port types.
