the ISDN card doesnt. Just as shown on http://de.bach-online.de/blog/?p=18.
I have one `old NT' (about from 1995, the A4 grey box model which worked quite well, where the `new' yellow square are really a mess), and I use it in NT mode with an HFC card to power the ISDN phones. The only issue I have to report after running about 3 months with it is that it will only power the bus if it is quickly connected to a real ISDN U bus for some seconds each time it is power-cycle.
As it is on an UPS, this was only an issue when we had a 1h30 power failure in Neuchâtel about 3 weeks ago.
I intend to buy 3 new NTs (not NT2abs) in the future, for use as real U bus NTs, and I think Elektro-Material AG has them. Probably those have the power feature too.
You can also buy ISDN power supplies from Beronet AG (http://shop.beronet.com).
