Ethernet Appliques
Ethernet appliques provide the external interfaces for CSC-MEC card ports. One or more appliques
are mounted on a connector plate, which is installed in the rear of the router. The 15-pin Ethernet
connector applique connects to a 10Base5 (thick -wire), 10Base2 (thin-wire), or 10BaseT (UTP)
network with the appropriate MAU or Ethernet transceiver. The 10BaseT applique connects to a
10BaseT network only and does not require an external transceiver. The following sections describe
the Ethernet appliques and some of the Ethernet transceivers you may need.
Ethernet 10BaseT
The Ethernet 10BaseT applique (see Figure 2) combines an RJ-45 connector for direct connection
to an unshielded twisted-pair (UTP) network segment and a UTP transceiver. The 10BaseT applique
is compliant with IEEE 802.3. The pinout for the 10BaseT RJ-45 connector is listed in Table 1.
