The older ETW phones will work, you just have to cross connect them to the second pair on the station cable (usually the white/orange) which connects to the yellow/black leads inside each jack.

Kind of a P.I.T.A to keep track of, especially if all your jacks don't have both pairs terminated.

If you don't need to use the ETW's then avoid it.

Took your advice Dog, ordered new DTU's. Now I have 8 ETW's for sale......anyone interested?
