Someone had told me that were only a fuse or 2 and some caps., But ain't so. The fuses are soldered in, I can tell you there's more crap inside than a few caps. Guess a schematic would help, if can remember how to read.
I once work on electronics for a small living and even fixed a few.

Plug-in surge protectors will even contribute to damage of the adjacent electronics. The telephone company has already installed an effective protector on your phone line. To meet code requirements, this protector must connect less than 20 feet to a building's ground rod also used by the electric box. Homes that meet code requirements before 1990 may not have the necessary grounding. Grounding and not the protector is protection. Therefore plug-in protectors are also grossly undersized.

Special low capacitance protectors are required for phone line protection - ie Sidactors. But without proper grounding, the protector does not protect anything. Any protector sold by Best Buy is better called a scam. Effective protectors are sold in Home Depot and Lowes.
