Anyone know what voltage gas tube lightning protectors to use on the talk and power/data pairs for a 509. After storms I keep losing ports on a station that's running through a buried cable to another building

Is there any protection currently in place?

Nope

my parts supplier Falcon Technologies has a dytec unit (DKT-PRJPOE) its for POE cat 6 but it has a 75V clamp I am wondering what the ringing voltage is on a partner ports center pair?

I know your basic gas tube protectors are 350V and are designed for CO lines. That's probably a No Bueno for a digital/electronic phone such as the partner ACS

I'm not sure if ETR phones require specific grounding/protection equipment.

I would have either the LEC or an Interconnect select and install the proper grounding units on both ends of the cable.
