Re: Renaming the WAN PHY
Bruce,
It is has never been stated by any of the presentors that the WAN compatible
PHY would in work on LAN implementations. Since P802.3ae is full duplex
point to point, for those people that want remote fiber trouble shooting
functionality, the WAN compatible PHY will work very well in the LAN. At
present, there has not been proposed a "WAN only PHY". Since the proposed
WAN compatible PHY is also compatible with LAN implementations, I propose
that we call it the "WLAN" PHY and the LAN only PHY can remain the "LAN"
PHY.
By the way, I am looking forward to when the service providers that are
offering retail customer network services over GbE MANs start having
maintenence issues. GbE works extreemely well, and is easy to set up and
operate, if there are no problems. When problems do occur, GbE becomes
extreemely difficult and labor intensive to support. Unlike most of the
people in the group, I have actually been designing, building, and
supporting large enterprise LANs, MANs, and WANs as a customer and user for
years. I am not showing disrespect for the high achievement and achidemic
expertise of the group or individual of the P802.3ae TF. I do have
disrespect for the inexperienced people that attempting to create service
provider companies using GbE.
Thank you,
Roy Bynum
