ATT uses Nitrogen to purge air from wire cables (That's becoming
rarer these days though with use of fiber optic phone lines.).
My apartment complex is on OLD wires & every so often when there is a
lot of static in the phone, a call to ATT (name your local phone
provider here) will get the issue fixed, that's the purpose of
nitrogen cylinders one occasionally see's on phone poles the end og a
street with copper wire lines.
After Hurricane IKE crippled much of the Houston/Galveston area, the
familiar dial tone was still heard on most hard-wire phone lines, as
cell users ran around 2+ weeks later with dead batteries (In cases
where they didn't have a cigarette lighter adapter to charge their
phones & the local cell towers were fortunate enough to have a
working generator).
