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 codec choice,
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, lowering
the number of speech 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. If using clusters, 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.
