2. Not sure EXACTLY what you need to know but I can try and post anything you need. Heres some stuff I found from modem diagnostics. Upstream Noise Margin noise margin upstream: 1 db output power downstream: 20 db attenuation upstream: 31 db
Downstream Noise Margin noise margin downstream: 24 db output power upstream: 12 db attenuation downstream: 49 db
Your line looks like it can handle at least the 1.5 Mbps service. 3.0 Mbps would be pushing it, but 1.5 Mbps should be stable.
• For 3 Mbps DSL the Downstream Attenuation must be under 48 dB with 10 dB SNR or better.
• For 6 Mbps DSL the Downstream Attenuation must be under 38 dB with 10-12 dB SNR or better.
WAN Port Statistics: Link Status: Up Upstream Speed: 287 kbps Downstream Speed: 571 kbps
Right now you are on the 0.5 Mbps Service aka 571/287 Sync Rate that should usually show 512/256 speed test results.
I would call in and asked to be placed on the 1.5 Mbps service and see what the Downstream SNR stabilizes at. The Attenuation should remain the same as it is a measurement of the lines electrical distance.
