If you put DS1N-14 cards in Slots 3 and 15 to form 1:N protecti on grou ps, do not wi re Slot s 3 and 15
for DS-1 electrical interface adapters.
Figure 1-28 shows a ONS 15454 backplane with an SMB EIA with DS-1 electrical interface adapters
attached on both sides of the shelf assembly to create DS-1 twisted-pair termination points.

1.11.2 AMP Champ Connector Installation
To install AMP Champ connector DS-1 cables, you must use 64-pin bundled cable connectors with a
64-pin male AMP Champ connector. Y o u need an AMP Cham p con n ect or #5 5 22 76- 1 for th e receptacle
side and #1-552496-1 (for cable diameter .475in.–.540in) or #2-552496-1 (for cable di amete r
.540in.–.605in.) for the right-angle shell housing (or the ir f unc tiona l e qu ivale nt). T he c or respon di ng
64-pin female AMP Champ connector on the AMP Champ EIA supports one receive and one transmit
for each DS-1 port for the corresponding card slot.
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. Table 1-5 shows the pin assignments
for the AMP Champ connectors on the ONS 15454 AMP Champ EIA. See the “AMP Champ EIA”
section on page 1-20 for more information about the AMP Champ EIA.
