Eclipse Median Instruction Manual
1 - 4
One CPU card is required for each Eclipse Median system. Two cards
can be installed to provide redundancy in the case of outages or repair
needs.
MVX-A16 Analog Port Card
An MVX-A16 analog port card controls the operation of panels and
interfaces connected to it. Panels and interfaces connect to the port
card through an RJ-45 connectors or “port” on the matrix’s rear panel.
Shielded category-5 cable attaches the panel or interface to the RJ-45
connector.
The MVX-A16 analog port card sends balanced audio and RS-422
data signals to connected audio equipment through 4-pair shielded
category-5 cable. The card connects up to 16 remote audio devices
such as intercom panels, interfaces, or 4-wire audio equipment to the
central matrix. Each audio device connected to a port card
communicates with all other audio devices in the system and with the
central matrix.
For intelligent linking, shielded category-5 cable is run from a port on
one Eclipse Median to a port on a second Eclipse Median to form a
trunkline connection.
E-FIB Fiber Interface
E-FIB fiber interfaces connect Eclipse matrices together to provide a
high speed, dual redundant link to transfer audio samples and data
between systems. These connections can be configured in various
ways to provide protection against the loss of a link or a node.
Each E-FIB fiber interface consists of a front card with various status
indicators and a rear card with two Duplex LC Terminated fiber optic
connectors (TXVRA and TXVRB).
E-QUE E1/T1 Interface
The E-QUE E1/T1 interface allows the Eclipse matrix connectivity to
FreeSpeak/CellCom antennas and FreeSpeak/CellCom antenna
splitters. Each E-QUE interface consists of a front card with a reset
button and various status indicators, and a rear card with eleven RJ45
ports giving eight standard ports, DECT sync in and out and a LAN
port for diagnostic use.
Each E-QUE front card has status LEDs for power, port activity and
LAN status. The port activity LEDs indicate whether there is a device
connected to an E1 port and that a connection has been established
between this port and the connected device.
The E-QUE interfaces must be fitted in the rightmost available slots
(furthest away from the CPU cards) on the Median and up to four
E-QUE interfaces can be fitted on a matrix.
