Spectralink Media Resource
The media resource is a print board that is placed within the same rack next to the Spectralink 
IP-DECT Server 6500 board. Up to 2 media resources can be placed in the same rack that houses 
the Spectralink IP-DECT Server 6500 board.
The media resource performs media conversion between the call handler and the Spectralink 
IP-DECT Server 6500 and is the media termination point for incoming and outgoing calls.
Each Spectralink IP-DECT Server 6500 contains one built in media resource.  The Spectralink 
IP-DECT Server 6500 can support a total of 32 media resources.  Each media resource adds 32 
voice channels.  The maximum number of simultaneous calls for a fully loaded system is 1024 
calls at the same time.  If secure RTP is enabled, however, the number of voice channels 
supported by each media resource decreases to 24. 
Spectralink Base Station
The base stations are positioned in the area to create coverage for DECT handset’s ability to make 
and receive calls and messages. The base station contains internal antennas and has 12 
channels. One channel is used for synchronization and 11 channels can be used simultaneously 
as speech channels. A base station is able to synchronize with other base stations. When the base 
station is synchronized with other base stations, a person speaking in a handset can move 
between base stations without any interference. This is known as seamless handover.
LAN transmission length is up to 100 meters/329 feet according to IEEE 802.3u on a twisted pair 
cable, minimum cat.5e. The base station can be powered by a power supply or by PoE. The base 
station is a class 1 PoE device (802.3af) and must be powered accordingly (maximum power 
supply consumption 3.0W according to PoE 802.3af). The radius coverage of the base station is 
up to 90 meters/295 feet indoor and up to 300 meters/984 feet outdoor, with a handset in 
line-of-sight. 
Coverage area decreases depending on choice of building materials and obstructive elements. To 
ensure proper coverage in the areas required, it is necessary to conduct a site survey and 
deployment by certified technicians. For more information about deployment, refer to the online 
Deployment Guide.
Spectralink Repeater
The repeater can be used to extend the coverage area in a wireless solution. The wireless 
repeater is used in areas with limited voice traffic, where cabling is difficult. The repeater does not 
increase the number of traffic channels, but increases the coverage area established with the base 
station. Up to three repeaters can be placed in cascade formation directing coverage in a certain 
direction.
The base station can support up to 3 repeaters. 
Spectralink Handset
The handset is a portable unit compatible with DECT GAP standard.
The handset is designed to provide the subscriber with most of the features available for a wired 
phone, in addition to its roaming and handover capabilities.
