No, really short POTS loops were not bad, but longer ones had
all sorts of things done to them (including those coils) that made
them undesirable for high-fidelity (good bandwidth + flat freq.
response). The telco had all sorts of ways of equalizing specially-
treated loops so you could get 5K or 15K response across town.
