Technically no would be the logically correct answer to your question I guess. No, there would not be no benefit to grounding the cable. In other words, there would be a benefit.

Including your ground bar field, tower grounds etc. Power grounds. Then one single cable called the ground window that comes into the C.O. ground bar. If you want to get fancy you use a PANI bar which has different types of equipment connected at different places. Isolated is I I think so most sensitive stuff. Stuff that is not even grounded to the racks. Back in the day of early digital central offices, those switches all had insulators between the chassis and racks. All those racks went to the I end of the ground bar. Then N Neutral, for the iron work connections. A was for absorbers. As in things that would absorb a surge so I think that is where the ground window cable attached. Then the P for producers. Maybe that was where the ground window attaches. So, technically yes.

There are signal transformers on both ends. It's this property which allows poe on the data lines to work as they inject power on the center tap of the line side of the magnetics. Of course the poe part isn't isolated unless power isolation is added as well.

I would basically look like a coupler with a ground wire attached to the shield. Much more basic than a surge suppressor. -Adam -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
