If the power receptacle earth ground or the telco earth ground are NOT
there I would call an certified electrician in (unless you own the building
and know exactly what you are doing) to get the problem corrected. If you
perform bonding between the telco earth ground and the power earth ground
and there already exists an alternate common ground then you can setup a
condition where you could be inducing electrical noise into your system by a
ground loop.
I have seen such a condition when I worked at the Cape (Kennedy) where an
electrical tech had bonded some equipment to a structure ground thinking the
earth ground connection was not in place and every time an electrical storm
would pass within 5 miles of the place the equipment would do strange things
( reset - lose data sync - stop processing information - you get the
picture ).
Just some info...
