Because each DS1-14 card supports 14 DS-1 ports, only 56 pins (28 pairs) of the 64-pin connector are used.
Prepare one 56-wire cable for each DS-1 facility installed.
Figure 1-19: AMP Champ EIA Backplane
Table 1-8 shows the pin assignments for the AMP Champ connectors on the ONS 15454 AMP Champ EIA.
The EIA side marked "A" hosts six AMP Champ connectors. The connectors are numbered 1 to 6 for the
corresponding slots on the shelf assembly. Each AMP Champ connector on the backplane supports 14 DS-1
ports for a DS1-14 card, and each connector features 28 live pairs-one transmit pair and one receive pair-for
each DS-1 port.
The EIA side marked "B" hosts six AMP Champ connectors. The connectors are labeled 12 to 17 for the
corresponding slots on the shelf assembly. Each AMP Champ connector on the backplane supports 14 DS-1
ports for a DS1-14 card, and each connector features 28 live pairs-one transmit pair and one receive pair-for
each DS-1 port.
Note: EIAs are hot-swappable. You do not need to disconnect power to install or remove EIAs.
Caution! Always use an electrostatic discharge (ESD) wristband when working with a powered ONS 15454.
Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
