Yes, E1553^™ has been designed to operate in parallel with legacy 1553 without impacting any of the legacy 1553 signaling. E1553 operates “out of band” of legacy 1553 and has been designed to not add any energy into the legacy 1553 band that could cause any change to the legacy 1553 signaling.

Just like other networking technologies such as Ethernet and Fibre-channel, and unlike legacy 1553, E1553^™ supports a Media Access Control (MAC) layer. The MAC layer adds overhead to the data being transmitted across the network. E1553’s MAC rate is typically between 65% and 70% of the PHY rate, which is very consistent with other networking technologies.

E1553^™ technology can support physical data rates in excess of 500Mbps. Edgewater has implemented and tested E1553 technology to 200Mbps. Under a governmental contract, Edgewater has developed a PMC card that supports a physical data rate of 100Mbps or 100 times the capacity of legacy 1553.

No. E1553^™ has been designed to operate on the existing 1553 data bus with the existing cabling, couplers, terminators etc...In fact, E1553 uses the same connector from the LRU onto the stub that is used by legacy 1553 without impacting the legacy 1553 signaling.
