Looking for some thoughts on 680.9 B,C about why Broadband has to be 22.5 ft away from the pool, but phone cabling can be as close as 10 ft?
How common is Network-Powered Broadband? It does not exist in my area. That is a system where the network provider provides both the communications signals and the power to the modem or other such device.
Thats what I have always thought network powered broadband was, the coax distribution 'amps' or whatever they are called in basements fed off big 1" coax cables, then smaller cables to the apartments.The closest I have seen is a cable TV installation with amplifiers powered by DC run on the coax along with the TV signals.
I thought Article 830 applies where the power comes in on the drop from the communications utility's system and not where the power is supplied after the point of entrance of the communications circuit.Thats what I have always thought network powered broadband was, the coax distribution 'amps' or whatever they are called in basements fed off big 1" coax cables, then smaller cables to the apartments.
In NYC buildings there is tons of that old stuff in basements, when they upgrade I have seen cables that are both coax and fiber and the box does not get power from the building, but there is an option to.
Out in the burbs you typically see them hanging on the overhead coax lines.
When doing service upgrades you know its network powered because some have green led's that stay on when the service is off.
Yeah exactly, I am no CATV expert but I see these big fat coax cables in the basement electrical rooms with those 'amps' or whatever mounted on plywood, you can see a green led or two in there, no receptacle near by no power input to them, and when I am working on the service con-ed kills the power those green led's are still blinking right there next to me and my work light. And when my battery dies I can see enough to replace the battery off all those blinking led's.I thought Article 830 applies where the power comes in on the drop from the communications utility's system

Could be a battery in them but I still see nothing but COAX in or out.
I think that likely depends on your local fire marshal / inspection dept.It's not covered by Art 830 as it powers distribution equipment owned be the cable company.
Building owners are really stingy, they never let the telco / cable co get a free ride, they'd have us install a sub meter or even a separate utility meter. For those building mounted cell sites they install a separate utility meter. Even the cost of installing the meter, and removal when lease is up, is born by the telco.Now, of course, they will run fiber into the building and the equipment will have be powered by power from the building (if it requires any power at all).
Are you talking about a cell site or other equipment serving multiple customers?Building owners are really stingy, they never let the telco / cable co get a free ride, they'd have us install a sub meter or even a separate utility meter.

Yes condo buildings in Manhattan, there could be several dozen residences in a building.Are you talking about a cell site or other equipment serving multiple customers?
