Description
The ONS 15454 SDH FMEC-T54-E1 card provides front mount electrical connection for twelve
ITU-compliant, G.703 E-3 or DS-3 ports. With FMEC-E3/DS3, each interface of an E3-12 card operates
at 34.368 MBits/s (Mbps), resp. each interface of a DS3I-N-12 card operates at 44.736 MBits/s (Mbps)
over a 75 ohms unbalanced 1.0/2.3 miniature coax connector. Figure 1 shows the FMEC-E3/DS3
faceplate and Figure 2 shows a block diagram of the card.
