Proprietary Information: Not for use or disclosure except by written agreement with Calix.
Calix recommends that the testing of grounds be conducted on a preventative maintenance
schedule to insure the maximum safety possible. Maintenance records should be kept for
each ONT installation. In some locations, extremely high earth ground resistance is present.
In these locations, chemicals that lower earth resistance can be added to the earth that
surrounds the electrode. This type of treatment must be done on a scheduled maintenance
routine complete with resistance records.
