For additional lightning protection, install gas discharge tubes with silicon avalanche
suppressors to ground (grounding rod or copper cold water pipe) on each CO trunk. This must
be done external to the system. Each gas discharge tube is installed directly between the
service provider company RJ-type block and the system CO/DID/OPX input. This protection
should provide energy absorption and filter low-level surge potentials. Also, in areas with
frequent occurrences of lightning, make the cable length between the service provider company
RJ-type blocks and the gas discharge tubes at least 75 ft (22.5 m). The cable may be coiled as
needed.
