This is all my opinion... take it or leave it.

I think it's unfair to blame Digex for the fact that the SLCs can't carry
the full bandwidth of a 28.8k modem. The specifications and particulars
of those circuits are beyond Digex's control and instead fall into the grand
monopoly of Bell Atlantic.

However, you could blame Digex for using this technique to handle remote
calling areas. As I understand it, the actual carrier is being shipped
down these SLCs to Digex's main POP. However, this isn't the only way
to handle remote numbers. A "more reasonable" solution, and one which puts
control of the circuit at least more in their control, is a true POP, which
is linked via leased-line to their main POP. At each remote POP, there would
be a modem pool, terminal servers, router and CSU/DSU. Thus, they wouldn't
be shipping analog carrier down the SLCs but instead would be shipping
digital data in which bandwidth can be controlled and somewhat guaranteed.

So the limitations of the SLCs are beyond Digex's control, and you can't
blame them for that. You can, if you like, blame them for using a method
that makes the limitations of the SLCs _their_ limitation as well. You
could also reasonable blame them for not investigating different options
as well.
