Colleagues,
 
During the October 3 ad hoc call we agreed not to meet today as it conflicted with a TR42 meeting which many of the cabling participants attend. An ad hoc meeting will be held next week October 17th. Sorry about the confusion for those not attending last week's call...I was traveling and had not had a chance to generate minutes (to follow)...Regards, Chris

Colleagues,

 

 

Subject: Channel definitions ad hoc minutes August 29

 

(1)Reviewed patent policy

(2)Reviewed IL proposal in (802.3bp baseline proposal-D0.2.pdf)

updated with ILD term

>>Discussion outcome: Consider IL proposal slide 16 ( 802.3bp baseline proposal-

D0.2.pdf) and IL proposal slide 5 (herman_3bp_01_0713.pdf) for baseline proposal discussion in York.

(3)Reviewed ---RL and alien crosstalk proposals (herman_3bp_01_0713.pdf)

>>Discussion outcome: 

+++Consensus to include RL  proposed limit (slide 10 - limit line in green-  herman_3bp_01_0713.pdf) for baseline proposal discussion in York

+++Consensus to include PSANEXT proposed limit  (slide 11  herman_3bp_01_0713.pdf) for baseline proposal discussion in York

+++Consensus to include PSAACRF proposed limit (slide 13 herman_3bp_01_0713.pdf) for baseline proposal discussion in York

(4)Reviewed ---Balance specifications (Mehmet RTPGE_EMC_Limit_Lines_06662013.pdf)

>>Discussion outcome:

+++Mehmet to bring a revised proposal for baseline proposal review discussion in York

(5)Time domain channel representation resulting from insertion loss (IL) (Anand Dabak dabak_3bp_01_0813)

>>Discussion outcome:

+++Link segment measurements (magnitude and phase) to be provided for PHY evaluation

(6)Reviewed presentation on cable balance measurements - (Michael Rucks RTPGEBalanceTestchannel_cableonly.pdf)

 >>Discussion:

+++Mode Conversion Limit Line proposed by Mehmet on slide 9 in RTPGE_EMC_Limit_Lines_06662013.pdf is very difficult meet and test fixtures and measurement methods are critical to achieving accurate balance of DUT.

 

(6)Reviewed presentation on EMC/channel ad hoc discussion of balance parameter requirements (Stefan Buntz - buntz_3bp_01_0829.pdf)

>>Discussion:  Stefan provided clarification of the different kinds of “link segments” under discussion as related to balance parameter discussion.

 

(7)Car manufacturer feedback on cabling
requirements questionnaire responses
(Kirsten Matheus 20130820_Matheus_ResultOEMquestions_v01.pdf)

+++Kirsten presented results and her conclusions

+++Material to be included in ad hoc area for reference
