Your Line attenuation is bad and I don't think a 60+ down attenuation can support 1024kbps... let alone 2600kbps. The max you might be able to get away with would be 512kbps.
The further you are from the central phone office the higher your line attenuation and the lower your SNR.
You basically want a low attenuation and a high snr.
You also have quite a few CRC and HEC errors for an 11 mins uptime. Add to that 10 loss of signal detections and I wouldn't be surprised you are having disconnections.
Start by asking your ISP if they can lower your "Bandwidth (Up/Down) [kbps/kbps to 256 /1024" and see if that helps.
