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. You need an AMP Champ connector #552276-1 for the receptacle
side and #1-552496-1 (for cable diameter .475in.–.540in) or #2-552496-1 (for cable diameter
.540in.–.605in.) for the right-angle shell housing (or their functional equivalent). The corresponding
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.
for the AMP Champ connectors on the ONS 15454 AMP Champ EIA. See the
