RE: Link Status thoughts
Hi Rich,
1. Can you explain in which cases /E/ is transmitted onto the XAUI
interface, and how should the receiver react in these cases?
2. Are there any agreements in the HSSG about Remote Fault and Break Link
signaling?
3. Any thoughts about Link Initialization?
These questions are mainly a concern for cross-connect equipment which work
in low levels, but need to supply solutions in broken link cases.
Thanks,
Lior.
