[10GMMF] Notes from Aug 3rd Meeting on TP3 Definition
Here are the notes from today's first meeting of the TP3 Definition Group
For attendees please see attached spreadsheet. If I missed anyone please let me know and I'll add them to the list.
Notes on Agenda Items
1. List attendees
2. Discuss Goals/Scope
Some discussion here. Action for Mike to re-word the draft version. This now reads as:-
o Present a proposal for TP3 specification parameters and associated conformance testing at the September Meeting
In support of this we need to:-
1. Agree on our Overall Test Philosphy (spelling out normative and informative tests reqd)
2. Determine and validate specific metrics which will be used to simplify test requirements
3. Provide detailed proposals regarding each individual test
These goals are my effor to capture the conversation and will be reviewed at the next meeting.
3. Agree Modus Operandi
- will meet weekly on Tuesday
Dial in info:
International Direct Dial (650) 599-0374
Meeting ID: 801803
- Smaller sub groups may form as the work takes shape and can be divided up.
- Post meeting notes and invites on the 10GMMF website
4. Agree Overall Testing Philosphy
Agreement was not reached. The discussion was focused on the stressed eye test with two viewpoints discussed. The
debate centered around whether the stressed eye test should be an accurate reflection of how to represent all known impairements (which could subsequently be test reduced by the vendor, depending on their design choices) or whether the test should be made as simple as could be defended in order to support making the test practical and repeatable.
I think there was agreement within the group to ulitmately provide a simple informative test but there was not agreement on the complexity vs completeness of the normative test.
Additional agenda items for subsequent meetings are as follows:-
5. Develope detailed work list (& interested parties) for more detailed analysis of individual tests:-
The following points have been taken from Lew's presentation (link above):-
- Normative Stressed Rx Sensitivity Test
o Is a 2 ray model sufficient as an ISI generator?
o What is the best choice for relative peak height and separation?
o Is a certain maximum bandwidth important?
o Define measurement for OMA
o Determine S/N requirements of compliance signal
o Define test procedures for calibrating conformance test signal
- Dynamic Adaptation Test
o Determine rate of adaptation required
o Determine channel simulator and time varying component
o Define exact test method
o Choose appropriate allocation for Dynamic Adaptation Penalty
- Informative Sensitivity Test
o Goals for test
o Use simple Gaussian ISI or 2 ray model for channel
o Detailed parameters of that channel emulator
6. Discuss impact of having the ISI block being prior to the E to O conversion.
- Effect of cross products and non-linear ISI
