Thanks Dave.
I take it the 19 endspan PSEs you have are
all from different vendors?
Do you know if this represent all, or most
midspan vendors presently in the market? Or are there a lot more than 19
midspan vendors out there?

At the UNH-IOL, of the 19 endpoint
PSEs in our testbed, 5 of them are Alternative B.

Alt-B?
Guys,
Someone just pointed out to me that an endspan PSE can use Alt-A,
Alt-B, or both. (See paragraph 33.2.1) I had forgotten about
this, assuming endspans were always Alt-A.
This would seem to complicate our plans to have endspans and
midspans share the load. Midspans always use Alt-B, so they can share
ONLY if the endspan uses Alt-A.
Does anyone know of any endspans that actually use Alt-B
(the spare pairs)? If so, please reply.
Steve
