http://www.lightningsafety.com/nlsi_lhm/IEEE_Guide.pdfIf a ground wire (equipment grounding conductor) from telephone equipment (or any other equipment) is connected to "its own" grounding electrode which might be a ground rod or a rebar within concrete, then that grounding electrode must be part of the building grounding electrode system which means being bonded to the service panel neutral bus using an appropriately sized wire (NEC sec. 250.66 and table 250.66), typically #4 copper for concrete rebar (sometimes called Ufer) electrodes and typically #6 copper for ground rods.
Yep, coax appears to come from street, right into house. That beige cable is either your ground (Unlikely), or inside phone wiring.Cable doesn't even appear to enter that box. You need to open to be sure but that could be a phone line. It might even be a fiber based on the size of it.
I don't know what those acronyms mean. What are you telling me?If you get DSL from your Telephone company, it will be "Dry Loop". Very few Telco's are running POT's and DSL on the same line, since it is cheaper to do everything through Digital equipment in VRAD's.
