Here's another thought, if you are ambitious. The Aastra 480i does not come with a transformer, and you won't get a transformer at radioshack with a 48vDC output. It's 48v because that is the standard battery voltage of telecom plants, so that's what IEEE decided to make the standard for 802.11af.
You can power a large or a little number of phones quite cheaply, if you are comfortable with having power present at all times (your office isn't changed around a lot). Order a 48v DC power supply from a company like electrosonic, or perhaps you can get one at surplus. Where your cable plant terminates, cross connect the white/blue pair together to your positive bus, and the white/brown pair to your negative bus. I would recommend fusing each drop separately at 1.5A. Each phone uses 1.2, so that gives you a little headroom. If you have a patch panel, you could wire pairs of jacks - white/green and white/orange straight through, with power connected to the other pairs on one of the jacks. This is a sort of do-it-yourself PoE injector, but is cheap, and scales very well. It only requires one wall socket to run many phones. It will work with any 802.1af compliant devices, as they must take power from these pairs. It does not itself comply with the standard, because it does not have a pilot voltage mechanism. If you pre-wired this device on a patch panel before hand, it would be easy to install, and be very tidy. It will also work with Gigabit ethernet. -Tim On May 18, 2006 17:40, Nabeel Jafferali wrote: > No, the P50 is a PoE splitter.
