Some telcos are starting to kill off legacy services as they reach the end
of their life cycle. I saw an application from Verizon in West Virginia
to modify their tariff to remove SMDS as a service. According to the
filing, no customers were using it and vendor support for it was coming to
an end. I'm assuming at some point that Verizon stopped selling the
service and quietly told any remaining customers that they needed to
transition to other services because SMDS would be turned off on a certain
date. I've heard of some LECs starting to mull dropping frame relay as a
supported service as well...
