Table 8-2: Key to E-QUE rear panel connectors
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 uppermost card (seen from the
front) is always the one which generates this signal.
This means that if the uppermost card is removed, or a new card is fitted
above 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.
The LAN port is used for diagnostic purposes.
8.3 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.
