Several times. When the weather improves and they start working again,
I'll corral a tech and ask him to open one up for photos. They're great
guys to a man/womam. It's a big cabinet--perhaps 10-12 feed long.
There are smaller cabinets there too, but they're mostly filled with wire.
What surprises me is the age of the customer copper. Folks around here
feed from individual pedestals on the road, using 5-pair buried cable
that's probably 30 or more years old to the residence. When the local
REC (rural electrical cooperative) came through about 5 years ago to
replace the buried individual 12KV customer feeds, it would have been a
golden opportunity to bury new customer lines, sadly ignored. So while
my electrical goes along the driveway from the disconnect on the road to
the transformer in my yard, the telco buried wire wanders across the
property among the trees until it finally enters the house.
During the BBS era, all of those 5 pairs saw use. Not so today.
