Network Interfaces
The network interfaces are full-duplex circuits provided by four
BNC coaxial cable connections (two for each controller card). The
receive data from the network is connected to the RX (
IN )
connectors, while the transmit data from the MX2800 STS-1 is
connected to the TX (
OUT ) connectors.
DSX-1/E1 Interfaces
The DSX-1/E1 interfaces are 64-pin Amp connectors. These
interfaces provide Tx and Rx connections between the unit and
equipment such as wire-wrap patch panels, punch-down panels, or
breakout panels.
Power Connection
The DC and AC power connections are described earlier in this
chapter on page 2-2.
Network interfaces must be connected using coaxial cables that have
the shields grounded at both ends.
Connect the DSX-1/E1 interfaces to intra-building wiring only.
