RE: Newbie question on draft 2.1

Title: Newbie question on draft 2.1

Hi, Robin,


I think you are referring to the 64B/66B PCS (Clause 49) and not the

WIS (Clause 50). The WIS doesn’t have any of the functionality you

are referring to (such as a Receive state machine). Is this right? You

might want to clarify this.


Best regards,


- Tom

Subject: Newbie question on draft 2.1



I'm violating the first law of reflectors here by asking a question before listening for a while, but the deadline, an unsuccessful search of the archive, and my confusion have forced the issue.  I apologize if I offend.

The first question is about the Local Fault ordered set when using a WIS (clause 49).  The  Link Fault Signaling state machine in the RS (clause 46) responds to received Local Fault ordered sets, but I cannot see where these are generated when using a WIS.  The far end RS doesn't seem to transmit a Local Fault ordered set (p.266), and I don't see anything in the WIS that would put it on the receive path.  Error blocks are generated, according to the WIS Receive state machine, but not ordered sets.  Could someone point me in the right direction?

The second question concerns error blocks.  The WIS defines EBLOCK_R as having /E/ in all 8 character locations, but the PCS shows figure 46-8 Reception with error as a single byte of /E/ surrounded by frame data.  Is this simply an old figure 46-8?

Thank you,
Robin Uyeshiro
