None. Your NID should already be connected with a ground wire to the ground rod for the meter. All newer NID's contain a jack that protects the line from Lightning, along with any line noise by filters that are inside the casing of the connection block. If you are in an apartment, you can get Lightning protectors from L-com.com. They need to be installed where the wiring is at for all phone lines and the ground connected to a Copper Cold Water Pipe. If you have PEX, you will have to ground it to the Breaker Panel.
