Very often, yes, but not always.
BTW, the example mentioned for the modem was ACTS + lockclock. I think
that's how NIST (at least used to) build out additional time server

Do we have any accuracy standards?
Given the screwups that can happen with bufferbloat, I'll bet it works much
better than some network connections.
It would be interesting to measure the delays on dial up lines. I wonder

The page for the modem driver says:
This driver requires a 9600 bps modem with a Hayes-compatible command

The actual line speed ranges from 1200 bps with USNO to 14,400 bps
with N
