Ahh ok, neither do I or the people I've spoken with about this.  In another
post I illustrated the Alvarion VL pin out is simply inverted.  Don't see
how that could make any difference in cross talk rejection.

So, can we expect Alvarion will at some point begin to adhere to industry
wiring codes?  

Several weeks ago you agreed a RSSI reading would be a good item to add.  Is
there any update as to when that will be available?

Best,

Brad

Frankly I'm not sure I actually buy the reason, but that's what I've been
told.

Patrick,

That is good to know, that there was actually technical merit, "brains", 
behind the decission to do it Alvarion's way.
I think whats more important from this is that anyone installing VL, and 
needing to extend the cable longer than the cable included with the unit, 
probably then also needs to wire the new longer cable or extenstion cable 
with the same pinout.
I bet many had attempted to use a 568B extension with a coupler to the 
Alvarion cable, if they were not aware of this.
The cable length that comes with it is probably fine for Residential, but 
for MTU's 150-300ft is not uncommon.
What is the cable limit for  Alvarion's CAT5 connection?

Now to give you a hard time.... Why does the Alvarion use 56V instead of 
standard 48V, 24V, or 802.11af?  :-)

So Brad, I finally have the answer as to why we do not use the standard 568B

(or 568A for that matter) pinot. We can't. The VL PoE pushes 55 volts and ½ 
an amp up the cat 5 cable. If the standard pinout is used the cable range 
due to cross talk can't make it much past 30 feet. With this pinout we are 
able to maintain the long distance.

So, you may not like it, but at least I've finally been able to give an 
actual reason.
