<div><div dir="auto">The few poles that have been mapped in my area (rural farming countryside) are the large cross-country grid feeders (generally 100Kv and up) and a few 9.6 Kv distribution lines. Having said that, it is my impression that 80%-90% of the telephony circuits are buried cables with cable tap boxes every 1/4-1/2 mile. The telco does use existing power poles for drop lines (from a cable tap to a residence) and occasionally strings overhead cables.</div><div dir="auto"><br></div><div dir="auto">Power poles (around here) have 4 designated (but invisible to the casual onlooker) segments: The electrified segment at the top, a guard section (in which no wires are connected), a telecommunications section, and a minimum ground clearance segment. The exact measurement/height of each segment varies based on the height of the pole and other factors.</div><div dir="auto"><br></div><div dir="auto">Without trying to off topic, something which is attendance with a few power poles is a telecommunications 'Remote Terminal' cluster. This is usually 2-4 vertical cabinets, one is a wire cabinet, and the others contain active electronics to support telephony/data circuits in a location far from the central office. In my case, the nearest such RT is 1 mile up the road, and 6 miles from the central office. It might be nice to map the locations of the (obviously present) RT boxes.</div><div dir="auto"><br></div><div dir="auto">Hope all this helps</div><br><div class="gmail_quote"><div>On Sun, May 26, 2019 at 7:56 PM Joseph Eisenberg <<a href="mailto:joseph.eisenberg@gmail.com">joseph.eisenberg@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Nita Rae,<br>

Do you know of any utility poles, telephone poles or other poles<br>
carrying communications cables that have been mapped in your area? How<br>
have they been tagged?<br>
<br>
Do you have a preference for how to map poles that don't carry any<br>
power wires or cables?<br>
