haven't had a chance to talk to my contractor yet, but one guy in MC Home Depot, where i'm window shopping, mentioned for the data/internet cabling, the control box usually used is just a hub. for the cable tv, it's usually just an ordinatry cable tv signal splitter. same with the telephone. he mentioned that the important thing is the cable used, and suggested to only use Belden brand.

oh well, i thought it was like an ibm home director network control center..
