Re: [802.3_B10K] Terminology Kickoff


What is the issue with PMA  and PMD in relation to the DWDM network?  From an IEEE perspective – they are two well defined terms, and i have not heard any confusion about this in relation to the discussion underway.

I would also add the following to the list:

              - Port 

              - PMA

              - PMD

              - MDI

As discussed on this week's ad hoc call, there is a need for us to spend
some time on terminology related to the proposed PHY over DWDM network, .
Establishing a common reference point for various terms will enable
effective discussions in our group and the industry.  

To that end - I am kicking off this thread to try and identify the terms
that we feel need defined related to this topic.  This will also serve as
input into a potential liaison to the ITU-T, where we will request their
respective definitions of these terms.

Terms identified so far include the following  (alphabetical order)

*            Channel
*            DWDM
*            In-line amplification
*            Lambda
*            Lane
*            Link
*            PHY
*            Point-to-point link
*            Signal
