Just feedback to the list.
I got several offline emails on this. According to those experiences
MiRICi-E3/T3 is working fine with J-series and MX80. One mentioned the
negotiation better to be "auto". One mentioned he is working with
RAD.com at project initiation phase for MX80 + MiRICi-E3/T3. He said
MiRICi-E3/T3 encapsulates Ethernet packets into T3 frames and need to
install MiRICi-E3/T3 on both side instead of MiRICi-E3/T3 onside +
native T3 card other side.


Thanks,
