You can install EIAs on one or both sides of the ONS 15454 backplane in any combination (in 
other words, AMP Champ on Side A and BNC on Side B or High-Density BNC on side A and 
SMB on side B, and so forth). 
 
As you face the rear of the ONS 15454 shelf assembly, the right-hand side is the A side and the 
left-hand side is the B side.  The top of the EIA connector columns are labeled with the 
corresponding slot number, and EIA connector pairs are marked transmit (Tx) and receive (Rx) to 
correspond to transmit and receive cables. 
 

 
The matrix provided in Table 6-5 describes the EIA configurations available for the ONS 15454.

You can use BNC EIAs for DS-3 and STS-1 electrical circuits.  BNC EIAs are interoperate with all 
of Cisco’s DS-3 cards (including the DS3XM-6) and the EC-1 card.  The ONS 15454 low-density 
BNC EIA supports 24 DS-3 circuits on each side of the ONS 15454 (24 transmit and 24 receive 
connectors).  If you install BNC EIAs on both sides of the shelf assembly, the ONS 15454 hosts 
up to 48 DS-3 circuits.  The BNC connectors on this EIA supports Trompeter UCBJ224 (75 ohm) 
4 leg connectors (King or ITT are also compatible).  Right-angle mating connectors for the 
connecting cable are AMP 413588-2 (75 Ohm) connectors.  If preferred, you can also use a 
straight connector of the same type.  Use RG-59/U cable to connect to the ONS 15454 BNC EIA.  
These cables are recommended to connect to a patch panel and are designed for long runs.  
Figure 6-17 shows the ONS 15454 with pre-installed BNC EIAs.
