When multiple E-QUE cards are fitted in a rack, one of the cards generates a clock signal,
which all other cards lock to, to ensure that all antennas remain in sync. The system is
designed such that the leftmost card (seen from the front) is always the one which generates
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.
Note: 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.
Note: The LAN port is used for diagnostic purposes.

E-QUE interface card applications

The E-QUE interface card may be used to connect:
• FreeSpeak/CellCom/FreeSpeak II antennas and splitters to an Eclipse HX matrix.
• Provide E1 and T1 connections to other systems.
Note: For more information about E1 and T1 cable pinouts and cable connections, see:
• 4.8 E1/T1 Matrix to Matrix straight cable connections.
