High-density EIAs are attached to the ONS 15310-MA shelf assembly backplane to provide up to 168 
transmit and receive DS-1 connections through six Champ connectors per side (A and B) or six transmit 
and receive DS-3/EC-1 connections through six BNC connectors per side. The EIAs are designed to 
support DS-1, DS-3, and EC-1 signals. The appropriate cable assembly is required depending on the type 
of signal. 

The HD expansion connectors on the high-density EIA are not supported in Software Release 7.0.x and 
earlier.

You can install EIAs on one or both sides of the ONS 15310-MA. As you face the rear of the shelf 
assembly, the right side is the A side (15310-EIA-HD-A) and the left side is the B side 
(15310-EIA-HD-B).
