It is a Speedtouch 610s. Seems like a pretty robust small biz class modem
but it could be the issue. We are just trying to determine what has changed
since we moved from ADSL to SDSL (which is when the issue started)

Here is what has changed

1) Contention on the internal network doubled to 8 users (used to be 4 users
on 2 slower ADSL lines

1a) There used to be 3 VLANs, 2 for voice, 1 for data; now there is 1 for
voice, one for data.

2) The modem is new with the SDSL line

3) We are using PPPoA vs. PPPoE

Thanks,
Geoff
