[802SEC] IEEE P802.3bw draft PAR and CSD response - 1 Twisted Pair 100 Mb/s Ethernet

Dear EC members,

In support of subclause 10.2 'IEEE 802 LMSC Approval' of the LMSC Operations Manual please find below the required information in respect to the IEEE P802.3bw Standard for Ethernet Amendment Physical Layer Specifications and Management Parameters for 100 Mb/s Operation over a Single Balanced Twisted Pair Cable (100BASE-T1): 1 Twisted Pair 100 Mb/s Ethernet PAR for consideration at the July 2014 plenary.

Best regards,
  David

[1] Draft PAR and CSD responses:

Draft PAR: <http://ieee802.org/3/1TPCESG/public/P802_3bw_PAR_220514.pdf>
CSD responses: <http://ieee802.org/3/1TPCESG/public/20140528_CSD_IEEE802_3bw.pdf>

[2] Explanatory technical background material:

Adoption of Ethernet into the new market area of automotive has generated a need for a 100 Mb/s solution that will operate over single balanced twisted pair cabling on a lower-performance channel as well as other applications, such as carbon footprint sensitive applications, that will benefit by a reduction in the number of wire pairs and magnetics. IEEE Std 802.3 does not currently support 100 Mb/s operation over single balanced twisted pair cabling.

[3] Status of the development of the PAR:

The draft PAR and CSD responses are pending IEEE 802.3 Working Group approval at the July 2014 plenary.

Since the submission deadline for the August 2014 NesCom meeting (11th July 2014) occurs prior to the date of the July IEEE 802 EC meeting, I will pre-submit this draft PAR to NesCom on the understanding that:

[a] Any changes to the draft PAR text resulting from the Plenary will be promptly communicated to the NesCom Administrator.
[b] Should the IEEE 802.3 Working Group not approve the submission, it will be removed from the IEEE 802 LMSC Executive Committee and NesCom agenda.
[c] Should the IEEE 802 LMSC Executive Committee not approve the submission, it will be removed from the NesCom agenda.
