Where I used to work, we had lots of dial POPs on SMDS, for good reasons
at the time. When we re-did our dial architecture around 2000-2001 to
move away from physical POPs, we got rid of the SMDS service. From what I
remember, the month-to-month pricing after the contract ended was pretty
ugly, so that was another incentive to dump it.
