rackmount units. Once a modular connector is wired, push it firmly into the rear panel NONCRITICAL or CRITICAL connector.

The alarm functions can be enabled or disabled through the ALARM RELAYS section of the CONFIGURATION menu (see the section Alarm Relays on page 3-18).

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.

Network interfaces must be connected using coaxial cables that have the shields grounded at both ends.

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.

Connect the DSX-1/E1 interfaces to intra-building wiring only.

Power Connection

The DC and AC power connections are described earlier in this chapter on page 2-2.
