House wiring question | DIRECTV Technical Forums

I have a junction box in my house where all the coaxial cables come in and go out. Most of it is pretty straight forward. There is one cable that comes in from the dish and connects to a 4-way green splitter. One port of the splitter goes out to the PI and the H24 receiver, another port goes out to the DECA BB and the last used port goes out to a DECA and my HR23. There are several other cables in the cabinet that are not connected that go to various other rooms in my house. The thing that has me confused is that there is a cable that comes in and is hooked to a 2-way splitter with a white label, used because I believe the CSR didn't have a better connector, that has another cable hooked to one of the out ports that then leaves the box. I have no idea what either end of those cables are hooked to. Can anyone give me an idea of what that connection is for? I only have two receivers that are connected for Whole-Home-DVR. I'm pretty sure that was done when the CSR came to hook up my WHDVR system. My father-in-law appears to have the same sort of connection in his box and he only has one receiver.

Thanks
