Other Solution Component
In addition to the Spectralink IP-DECT Server, a Spectralink IP-DECT Server configuration can
include a number of the following components:
l
Spectralink DECT Media Resources (only Spectralink IP-DECT Server 6500)
l
Spectralink IP-DECT Base Stations
l
Spectralink DECT Repeaters
To handle the calls in the solution a call handler (IP-PBX SIP) is used.

Description - Spectralink DECT Media Resource
The Spectralink DECT 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 Spectralink DECT Media Resources can be
placed in the same rack that houses the Spectralink IP-DECT Server 6500 board.
The Spectralink DECT 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 Spectralink DECT Media Resources.
Each Spectralink DECT Media Resource adds 32 voice channels. The maximum number of sim-
ultaneous calls for a fully loaded system is 1024 calls at the same time. Depending on SRTP settings
and codec choise, the number of voice channels per Media Resource card can vary from 12 - 32.
G.726 allows for 32 duplex speech 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 speech channels on the Spectralink DECT Media Resource.
The Spectralink DECT Media Resource connects directly with the LAN and must operate in con-
junction with the Spectralink IP-DECT Server 6500. If using clusters, the Spectralink DECT Media
Resources can be placed at different locations.
