this signal. This means that if the leftmost card is removed, or a new
card is fitted to the left of existing cards, the antennas will lose lock for
a few seconds as the cards re-configure themselves and a new card
starts generating the sync signal.
Where multiple connected matrices are used containing E-QUE cards
the DECT reference ports are connected as a daisy chain between the
matrices to ensure that the DECT signals are synchronized through all
the E-QUE cards present in the matrices. Failure to connect the DECT
sync signal between matrices will result in poor utilization of the DECT
bandwidth, and the system may operate poorly in a congested RF
environment.
The LAN port is used for diagnostic purposes.
E-QUE INTERFACE APPLICATIONS
The E-QUE interface may be used to connect FreeSpeak/CellCom
antennas and splitters to an Eclipse matrix system or to provide E1
and T1 connections to other systems.
Information on E1 and T1 cable pinouts and cable connections are
given in chapter 6.
FREESPEAK/CELLCOM APPLICATION
The E-QUE interfaces can be configured for FreeSpeak/CellCom use
in two modes depending on whether antennas or splitters are to be
connected.
If the E-QUE interface is configured in ‘Antenna’ mode all eight E1/T1
ports can be used to connect up to eight antennas. If the E-QUE
interface is configured to support splitters only two ports are active
(ports 1 and 5) allowing a maximum of two splitters to be connected.
Each splitter can support up to five antennas.
When the E-QUE interfaces are used in FreeSpeak/CellCom mode
they cannot be connected to the antennas via third party equipment or
via fiber as the antennas require the DECT sync signal and this will not
be converted by third party equipment or fiber interfaces.
Three connections schemes are illustrated below.
