Figure 2-8. FCD-E1 with a Sublink and Additional Ethernet Port
The rear panels shown in Figure 2-6, Figure 2-7 and Figure 2-8 are for AC powered
units. For DC-powered units, a circular three-pin DC power connector is used. In
addition to the connectors located on the rear panel, the FCD-E1 has an additional
supervisory port connector, located on the front panel.
Connecting the Electrical Main Link and Sublink
The main link port, in the electrical interface version, and the sublink port have
two interfaces: a 120Ω balanced line interface, terminated in an RJ-45 eight-pin
connector, and a 75Ω unbalanced interface, terminated in two BNC coaxial
connectors.
Appendix A provides the pin allocation for the RJ-45 connector.
