Yup, if you Google PDI Splitter then eBay comes right up. Problem is I'm having problems finding a single 3-way one; I've seen lots of 100, 4-way, etc. If I get a 4-way then I need a terminator.
Look, this should be the worst thing that ever happens to me but it is a bit of a pain (I mean I'm not going to pay however much to have Verizon send a truck here, maybe I can get one from a tech who's here installing someone else's FIOS).
