I'm sorry, but you cannot use a 1-bit A/D converter for this application.
The cost of the circuitry and software development time would make it
completely unworthy of design for high throughput and error-free
operation.
Besides, you have different requirements for signal input than signal
output. A 1-bit D/A converter is NEVER used in commercial-grade
telecommunications equipment, and for good reason.

Irrelavent -- you need something that is sensitive enough to detect phase
errors and similar effects of long-haul audio transmission. :) I don't
care how much you over-sample; you still need resolution!

Still more affordable than a WebTV... :D Will it support FORTH applets?
