SpectraLink 8000 Telephony Gateway Administration Guide
IP multicast addresses are used by the SpectraLink i640 and 8030
Wireless Telephone. This requires that multicasting be enabled on
the subnet used for the SpectraLink 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.
Location of SpectraLink 8000
Telephony Gateway and SVP Server
The specifications covered here allow for great flexibility in physical
placement of the components within stated guidelines.
Each SpectraLink 8000 Telephony Gateway and SpectraLink 8000 SVP
Server measures approximately 4 x 12.5 x 7 inches, and weighs about
five pounds. The units are designed to be wall mounted—vertically or
horizontally—over 3/4” plywood or mounted in a standard 19-inch
rack mount cabinet with a Rack Mount Kit.
Locate the SpectraLink 8000 Telephony Gateway and SpectraLink
8000 SVP Server in a space with:
• Sufficient backboard mounting space and proximity to the LAN
access device (switched Ethernet switch), telephone switch, and
power source.
• Easy access to the front panel, which is used for cabling.
• For the SpectraLink 8000 Telephony Gateway, a maximum
distance of 250 feet from the host telephone switch for a digital
interface, and 325 feet (100 meters) from the Ethernet switch.
• For the SpectraLink 8000 SVP Server, a maximum distance of 325
feet (100 meters) from the Ethernet switch.
