There are many power bars out there that have an RJ jack in them to pass through and offer some form of surge protection.. But the only reliable way to protect against lightning is to create a nice physical gap.. unplug it.

"Unplug it" is not really an option if it storms very often. Start with verifying that the Telco has a modern Dmark with gas protectors and that it is tied to your service ground electrode system. Then use a point of use protector where the DSL modem plugs in that catches the phone and power. You should already have a panel protector if it ever storms there. I suspect the telco is as interested in protecting their modem as much as you are. That will be ground zero if there is a strike. I know when I had DSL installed they gave me a new Dmark and a fatter ground wire to my existing ground rod(s).

One of the trick with lightning is making sure that all protection is tied to the same ground, so that no difference in potential exists between grounds. Make sure that the telephone, catv, electrical, satellite, and any other grounds all tie to the same place, and that all grounds are properly tied together to form a complete grounding system.
The concept is that a lightning strike is going to raise the ground potential of the surrounding area, and that by having all ground tied together as a complete system, you attempt to eliminate the differential between grounding points.
By typing all the grounds together at the perimeter, you attempt to keep the lightning from entering the structure in search of a better ground.
ITW Links makes great electronic protection. The primary from the nid is ok but you will need secondary. Make sure you connect the ground on the secondary to the known good ground or you will not have a loop. If you dont know were that is just follow the nid ground.
