3.10 FMEC E1-120NP Card
The ONS 15454 SDH FMEC E1-120NP card provides front mount electrical connection for
42 ITU-compliant, G.703 E-1 ports. With the FMEC E1-120NP card, each E1-42 port operates at
2.048 Mbps over a 120-ohm balanced interface. Twenty-one interfaces are led through one common
Molex 96-pin LFH connector. Figure 3-9 shows the FMEC E1-120NP faceplate and block diagram.
Caution This interface can only be connected to SELV circuits. The interface is not intended for connection to
any Australian telecommunications network without the written consent of the network manager.
