The EIA side marked “A” hosts 84 SMB connectors in six columns of 14 connectors. The “A” side
columns are numbered 1 to 6 and correspond to Slots 1 to 6 on the shelf assembly. The EIA side
marked “B” hosts an additional 84 SMB connectors in six columns of 14 connectors. The “B” side
columns are numbered 12 to 17 and correspond to Slots 12 to 17 on the shelf assembly. The
connector rows are numbered 1 to 14 and correspond to the 14 ports on a DS-1 card.
For DS-3 or EC-1, the EIA supports 72 transmit and 72 receive connectors, for a total of 144 SMB
connectors (72 circuits). If you use a DS-3 or EC-1 card, only Ports 1 to 12 are active. If you use
a DS3XM-6 card, only Ports 1 to 6 are active. The SMB connector pairs are marked “Tx” and “Rx”
to identify transmit and receive cables for each port. If you use SMB connectors, you can install
DS-1, DS-3, or EC-1 cards in any multispeed slot (Slots 1 to 4 or 14 to 17).

AMP Champ EIA
The ONS 15454 AMP Champ EIA supports 64-pin (32 pair) AMP Champ connectors for each slot
on both sides of the shelf assembly where the EIA is installed. Cisco AMP Champ connectors
are female AMP # 552246-1 with AMP # 552562-2 bail locks. Each AMP Champ connector
supports 14 DS-1 ports. You can use AMP Champ EIAs with DS-1 cards only. Figure 6-21
shows the ONS 15454 with pre-installed AMP Champ EIAs and the corresponding sheet metal
cover and screw locations for the EIA.
Figure 6-21: AMP EIA Champ Backplane
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.
