Delayed Verizon calls (David LaRue)
Re: Southern New Jersey residents want fairness from Verizon (Neal McLain)

Oh dear Pan and all the other gods of this place, grant that I may be beautiful inside. Let all my external possessions be in friendly harmony with what is within. May I consider the wise man rich. As for gold, let me have as much as a moderate man could bear and carry with him.

Subject: Delayed Verizon calls Message-ID: <XnsA503BDC7EE2C507d764ee9285@> Hello, My wife and I have both experienced delayed missed calls that go to voice mail. The latest one that came in this afternoon on the ride home was made on Sunday afternoon. That is a four day delay. The issue doesn't happen all that often but when it does the call is reported several days later. Does this happen to other people? Thank you, David

No. Think hurricanes. Or blizzards. Or > haboobs. Or smoke from wildfires.] As others have pointed out, cell towers don't get their operating power from central offices -- they get it from local electrical power utilities. Check out any cell tower and you'll see power lines feeding equipment buildings. Cell buildings require power for lots of things besides transmitters and receivers -- things like test equipment, interior lighting, exterior lighting, HVAC equipment, and tower lighting. Many cell towers support antennas owned by two or more companies. In such cases each company may have a separate equipment building or it may share space other cell companies. Cell antennas may be located on existing buildings such as hotels, office buildings, churches, or schools. Antennas may be mounted on exterior walls or roofs. In such cases equipment is located inside the building and gets power from the building electrical systems. Cell antennas may be located on other structures such as water towers, microwave towers, broadcast towers, cable TV towers, streetlights, industrial chimneys, or electrical transmission line towers. In such cases the equipment may be located in existing buildings or in separate buildings owned by the cell company. A case in point: the WHNT-TV broadcast tower in Huntsville supports a cell antenna array; equipment is located in the station's transmitter building at the base of the tower. And, of course, cell antennas may be located inside of, or disguised as, any number of things. I have several examples on my blog: http://antennastructures.blogspot.com/ Whatever the situation, the equipment gets operating power from the local power utility, either as a direct customer or as part of a lease agreement with a third party building owner. Neal McLain ***** Moderator's Note ***** When ILECs were still leasing PBXes, it was common for the PBX backup batteries to be charged from the CO, using multiple pairs of wire in a trunk cable.
