WIS overhead - G1 RDI-P field

["Erik Trounce" <erikt@xxxxxxxxxxxxxxxxxx>]

Hello all,

I've noticed that the RDI-P field of the G1 overhead byte
is still undefined in the latest WIS update.
<http://grouper.ieee.org/groups/802/3/ae/public/jul00/figueira_1_0700.pdf>

However, the WIS update document does state in the Cross-References
section (on page 38) that ERDI-P is supported.  ANSI T1.416-1999
references ANSI T1.105-1995 which defines ERDI-P in Table 9 on
page 38.  Some questions:

1. will 802.3ae use the ERDI-P as defined by Table 9?
2. will LCD-P be used for anything (e.g. indicate loss of PCS codeword
delineation)?
3. will 802.3ae equipment have to support RDI-P as well as ERDI-P?

As currently defined, all ERDI-P would be used for is detecting
far-end PLM-P, AIS-P and LOP-P.  Are any enhancements envisioned?

Cheers,
