In other words, a PCI-based co-processor would double the PCI bus bandwidth necessary. And with a latency-sensitive product like voice, bus contention is not something you want to add to! :)
It only 'doubles the bandwidth required' when compared to a single-board solution, which does not exist. When compared to doing the transcoding and echo can in the host CPU, it would be a major win :-)
Also, keep in mind that a DS3 is _only_ 45 megabits per second. Any PCI bus (even lowly 33MHz 32-bit PCI) can easily handle 90 megabits per second of traffic. People looking a DS3 cards are also likely to deploy them in servers with multiple independent PCI buses, which would then allow for even more bandwidth. The mind boggles at the possibilities!
