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 synchronised through all
the E-Que cards present in the matrices. Failure to connect the DECT
sync signal between matrices will result in poor utilisation 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 CARD APPLICATIONS
The E-Que card 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 5.
FREESPEAK/CELLCOM APPLICATION
The E-Que cards can be configured for FreeSpeak/CellCom use in two
modes depending on whether antennas or splitters are to be
connected.
If the E-Que card is configured in ‘Antenna’ mode all eight E1/T1 ports
can be used to connect up to eight antennas. If the E-Que card 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 cards 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.
