The bit rate is 10M-bps rather than 1M-bps in legacy MIL-STD-1553, speeds up the transfer by a factor of 10.

Using a network topology of a star between BC and Remote Terminals traditionally uses only one of the RT links, but in theory may support multiple BCs communicating with multiple RTs in parallel on all links concurrently.

For example, legacy 1553 can transfer 1 M-bps to, say, four RTs. Maximum rate would be 250 Kbps for each.

EBR-1553 can transfer 10 Mbps to those four RTs at 2.5M bps each.

4 x EBR-1553 BCs can transfer 40 Mbps in parallel, each RT is getting 10 Mbps. 

So potentially, EBR-1553 with star topology can deliver 40 x faster.

With tomorrow’s munitions, these rates are highly required.
