Chapter 3 Electrical Cards
3.13.1 E1-75/120 Impedance Conversion Panel Functionality
3.13.1 E1-75/120 Impedance Conversion Panel Functionality
You can install the E1-75/120 conversion panel in the rack containing the ONS 15454 SDH shelf or in a
nearby rack. If you install the E1-75/120 conversion panel in a place where a longer cable is required,
make sure that the total cable loss of the balanced 120-ohm cable and the unbalanced 75-ohm cable does
not exceed the maximum allowed value. The E1-75/120 conversion panel enables the use of 75-ohm
interfaces on client side with the E1-42 card that has 120-ohm interfaces.
Before you can install the E1-75/120 in the rack, install the type of rackmount brackets that is required
for the rack that you are using.
3.14 FMEC-E3/DS3 Card
The ONS 15454 SDH FMEC-E3/DS3 card provides front mount electrical connection for
12 ITU-compliant, G.703 E-3 or DS-3 ports. With the FMEC-E3/DS3 card, each interface of an E3-12
card operates at 34.368 Mbps and each interface of a DS3i-N-12 card operates at 44.736 Mbps over a
75-ohm unbalanced coaxial 1.0/2.3 miniature coax connector. Figure 3-15 shows the FMEC-E3/DS3
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.
Figure 3-15 FMEC-E3/DS3 Faceplate and Block Diagram
You can install the FMEC-E3/DS3 card in any EFCA slot from Slot 18 to 22 or Slot 25 to 29 on the
ONS 15454 SDH. Each FMEC-E3/DS3 card interface features E3-level or DS3-level inputs and outputs
supporting cable losses:
• E3 signals
–
Up to 12 dB at 17184 kHz
• DS3 signals. One of the following;
–
Up to 137 m (450 ft) 734A, RG59, or 728A
