[EFM] RE: [EFM-Copper] Copper schedule in LAX (and beyond...)
Hugh and Howard, All,
Sorry that I have to leave Thurs afternoon for Stanford Conference on
Copper, but here are some thoughts:
one of the areas that I am interested to focus on is first and for most the
simulation environment. We have had couple of conference call on this
subject in the past two months and we have made good progress.
Here is the summary of what is needed (from everybody) and I certainly like
to see good contributions as I am trying to put EFM data rate analysis
We agreed we need to break copper loops in to two areas:
Public Plant/Network and MxU Network
We are collecting input right now and two groups are working together to put
this in to play:
The first Item that we like to address is public loop plants. We hope to
have an early draft document in Austin to discuss this. Hopefully by January
interim meeting we can close this! OK may be.
Next we like to have an early draft of MxU loop plants in the presence or
absence of public loops. This is a new area to everybody. It include issues
such as cable models, interaction of different cable types, etc. Based the
early work that we are reviewing we like to close this by March or May time
Next topic is modeling of all noise sources interferences and inclusion of
all noise sources. A lot of Next and Fext models don't work very well. This
is important because we need more upstream bandwidth. Spectral compatibility
and Dynamic spectral Compatibility, stationary noise and non-stationary
noise models are mostly new work that needs to be taken in to account. I
really wish that we might get a handle of that and get some sense of it by
May 02, may be even Nov 02.
This is the ground work that we need to do allow simulation to be evaluated
fairly. The plan is to use as much work that is done by ANSI, ETSI and
ITU-T. I have been in touch with various group in these organization to get
their participation here at EFM and we could all benefit from that.

Subject: [EFM-Copper] Copper schedule in LAX (and beyond...)
First of all, I would like to apologize to all those who received two copies
e-mail. If you are interested in the copper track and didn't receive two
you need to register for the copper mailing list.
If you are not interested in the copper track then stop reading here...
Follow this link to read instructions for the mailing lists.
Finally, the payload data....
In LAX we will have 1.5 days of meetings to ourselves. The EPON people will
alone and we can concentrate on Resistance, Inductance, Current Density and
concepts which would otherwise upset the optical folk. Currently we have 15
presentations submitted covering rate and reach; theoretical analysis; PMD
general requirements and 1 new objective. My estimate is that we will
cover these presentations on Wednesday afternoon and Thursday morning -
Thursday afternoon for free-range discussions before we rejoin the group on
I would like to use this "spare time" to (pre) discuss the new objective and
simulation / test ad hoc. I would also like to allow some time for a
discuss rate mechanism / operation (as I mention in my recap presentation)
other (copper) business.
Time is very short, so it will be hard to prepare for the Austin Plenary. I
that we use the spare time and gaps to work towards the baseline
will be needed in November. This means that you should all be trying to seek
minded people and sharing your ideas for November presentations.
I will send a copy of my recap presentation on the copper reflector - it
will also go
onto the website.
