Hi Howard, I have few questions regarding the Operator requirements (pertaining to physical layer): Service coexistence issues and criteria Services to be provided over EPoC HEB> Do you mean residential and business services or video, IPTV, VoIP, data services ? and how they will evolve over time Business vs residential services
(will they exist on the same network?) Asymmetry vs. symmetry Existing cable plant characteristics Architectures (Node+0 "passive", Node+N [N=1-?], Complete HFC, MxU)
Amplifier characteristics and considerations that will effect the PHY Cable & passives characteristics Typical size of cable plant HEB> I am not sure how you measure the size ? (number of home passed, size of coverage area, number of nodes, … etc). Subscribers passed Number and size of taps Changes to cable plant characteristics over time
(e.g. passive and active element changes, any use of bypasses?) Spectral allocation and how it changes over time Which frequencies are amplified and which are passive ` What spectrum will be allocated for EPoC initially,
and how will that change over time Regional differences for changes? Functional Assumptions and Impairments DOCSIS 3.0 has already characterized in CM-SP-PHYv3.0-I05-070803, Chapter 5, and in CM-SP-DRFI-I12-111117, Chapter 5, for "in amplified" regions of
cable. For both "in amplified" and "passive" EPoC considerations, are
there any additonal functional assumptions and impairments that need to
be considered for up to 1Gbps and higher operation?
How will these change over time? Are there regional differences; e.g. China, Europe? Number of subscribers per network, take rate Minimum required channel data rate Maximum desired channel data rate Thanks Hesham -----Original Message----- The first meeting of the IEEE 802.3 EPON Protocol over Coax (EPoC) PHY Study Group will be held January 24th and 25th in Newport Beach, CA, hosted by the Ethernet Alliance. Please see my previous message for links to meeting logistical
details. In preparation for the meeting, Mark Laubach and I put together a list of topics that can help us prepare for a successful study group meeting, and these are listed in the attached file. The first set of topics deals with the IEEE 802 standards development process. I have all of the material I need for this section, and I am sure that I will be able to enlist the help of some of our experienced hands to deliver it. The second set of topics deals with operator requirements, and this is where I would like to make an appeal for contributions. We may not get contributions that address all of the topics listed, and there may not even be universal agreement
that the topics are relevant, but I think that these are areas that must be explored in the study group if we are to do a proper job of defining the scope of a new project, and judging it against the "5 Criteria". People wishing to make a contribution to the study group should review the "Procedure for Presenters" information that can be found here: http://www.ieee802.org/3/epoc/public/presentproc.html Since this is a new email reflector, I would also like to make people aware of the IEEE 802.3 Working Group email reflector policy that can be found here: http://www.ieee802.org/3/reflector_policy.html I will welcome your comments and questions.
