Site Preparation
LAN Requirements
Network infrastructure
The SpectraLink 8000 Telephony Gateway connects to your local area
network (LAN). To provide adequate bandwidth and limit collisions,
an Ethernet switch is required. The traffic between the SpectraLink
8000 Telephony Gateway and wireless LAN APs should be isolated as
much as possible to avoid additional latency. The SpectraLink 8000
Telephony Gateway and APs must be on the same logical IP subnet.
Inter-subnet roaming is not permitted for wireless devices.
Each SpectraLink 8000 Telephony Gateway to be installed requires a
10 Mb/s switched Ethernet connection.
The SpectraLink 8000 Telephony Gateway and wireless telephones
rely on wireless LAN APs to transmit and receive packets from
wireless telephone devices. The APs must be compatible with the
IEEE 802.11 standard for wireless LANs, either frequency hopping or
direct sequence spread spectrum radios. To configure a wireless LAN
to support SpectraLink 8000 Telephony Gateways and wireless
telephones refer to Best Practices for Deploying Enterprise-Grade Wi-Fi
Telephony.
IP addressing
The SpectraLink 8000 Telephony Gateway, along with each of the
handsets associated with it, requires an IP address. The system
administrator must determine what IP addresses are to be used by the
SpectraLink 8000 Telephony Gateway and APs. Handsets can be
configured to use DHCP or Static IP addressing. Record IP address
assignments on the Wireless Device Planning Worksheets—one for each
SpectraLink 8000 Telephony Gateway. These worksheets may be
started when the system is installed. The information recorded on
them is used in the configuration and continuing administration of
the system.
