I understand that's your employer, but in my experience having a black box that doesn't give me visibility into the connection state easily (SNR, attenuation, constellation/bits per bin, etc) isn't nearly as useful as having an ADSL NIC actually in the router itself that can be easily queried for performance.
For instance, in one scenario we had a line that would train up at different speeds depending on how much rain we got... which messed with traffic-shaping. We could either crank the shaping way down to "work case", or we could script the box to query the NIC for the actual speed and then plug that value into the traffic shaping config. Worked out quite nicely. Not something I could have done with an external modem.
