Description - Spectralink DECT Media Resource
The Spectralink DECT Media Resource can be used with Spectralink IP-DECT Server 6500 and
Spectralink Virtual IP-DECT Server One.
The Spectralink DECT Media Resource performs media conversion between the call handler and
the Spectralink IP-DECT Server 6500/Spectralink Virtual IP-DECT Server One and is the media ter-
mination point for incoming and outgoing calls.
If used with Spectralink IP-DECT Server 6500
: The Spectralink DECT Media Resource is a print
board that is placed within the same cabinet next to the Spectralink IP-DECT Server 6500 board. Up
to 2 Spectralink DECT Media Resources can be placed in the same cabinet that houses the Spec-
tralink IP-DECT Server 6500 board. If more media resources is needed, it is necessary to acquisition
a media resource cabinet. The media resource cabinet comes with one media resource print board
and the possibility of installing up to two more media resource print boards.
If used with Spectralink Virtual IP-DECT Server One
: Acquisition of a media resource cabinet i
required. The media resource cabinet comes with one media resource print board and the possibility
of installing up to two more media resource print boards. Each Spectralink Virtual IP-DECT Server
One contains 32 built in media channels if the Mandatory Base Licence ARI 150 Users 64 Base Sta-
tions 32 Media Channels | Virtual IP-DECT Server License is installed. The Spectralink Virtual IP-
DECT Server One supports a total of 1024 media channels - up to 31 media resource print boards
(11 cabinets in total).
Each Spectralink DECT Media Resource adds 32 media channels. The maximum number of sim-
ultaneous calls for a fully loaded system is 1024 calls at the same time. Depending on codec choice,
the number of media channels per Media Resource card can vary from 12 - 32.
G.726 allows for 32 duplex traffic channels as this codec requires no processing and is routed dir-
ectly to the Spectralink IP-DECT Base Station. Other codecs such as G.711 or G.729 must be con-
verted to G.726 before routed further on to the Spectralink IP-DECT Base Station and this affects
the total number of available media channels on the Spectralink DECT Media Resource, lowering
the number of media channels down to 12 if all calls utilize the G.729 codec.
The Spectralink DECT Media Resource connects directly with the LAN and must operate in con-
junction with the Spectralink IP-DECT Server 6500/Spectralink Virtual IP-DECT Server One. If
using sites, the Spectralink DECT Media Resources can be placed at different locations.
The Spectralink DECT Media Resource contains no radio parts. It ships from the factory configured
for DHCP. Should it enter an unrecoverable state, it can be reset to factory default settings when the
reset button is pressed and held for more than 5 seconds.
