In some large multi-studio FreeSpeak or CellCom installs it maybe necessary to have antennas connected to one Eclipse matrix located in the same area (corridors, reception areas) as another set of antennas from a different Eclipse matrix.
Typically this maybe the case Studio-1 matrix including EQUE card for CellCom operation has antennas in the main scenery corridor Studio-2 matrix including EQUE card for CellCom operation has antennas in the same main scenery corridor
Therefore we have two independent DECT systems operating in the same RF space. DECT is designed to handle this situation with best selection of clean RF channels and auto handover between best available RF channels. However there is some loss in RF channel efficiency
When multiple Eclipse frames operate antennas in the same DECT space in order to provide the best carrier frequency efficiency the DECT sync of the different matrices should be locked together so that antennas connected to the Studio-1 matrix EQUE card do not RF drift over other antennas connected to Studio-2 matrix EQUE cardFor this reason the EQUE card does provide for an external DECT sync in / out connectors
See this FAQ for the DECT Sync IN / OUT pinout details DECT Sync pinout and signal details
What if any system issues might one expect with the wireless operation of each frame if the DECT sync connection is ignored?
