I think you will have to live with the 52 volts dc. It's pretty much the norm for LightSpan and I am not aware of any way to adjust them. After re-reading my last sentence in my post above, I should say that what you need to check for is that you are getting 90vac of ringing voltage when a call is inbound, there shouldn't always be 90Vac on the line. As for calling Alcatel-Lucent...I wouldn't recommend it. Not sure how AT&T does it but you could ask the engineer about getting a tech out that is responsible for the upkeep of their electronics and maybe the tech could call into tech support. Besides swapping boards there isn't much you can do with LightSpan unless you are logged into the system.
