Snr and Router Stats

Could anybody interpret the following stats for me. They were aquired with the DMT tool on my voyager 2500v ? I am a no Techie so please keep it simple.

adslctl: ADSL driver and PHY status
Status: Showtime Channel: FAST, Upstream rate = 448 Kbps, Downstream rate = 5728 Kbps
Link Power State: L0
Mode: G.DMT
Channel: Fast
Trellis: ON
Line Status: No Defect
Training Status: Showtime

Thanks in advance. This was after Interleaving was turned off last night.

SNR (dB): 5.1 21.0

Attn(dB): 47.0 27.0

Rate (Kbps): 5728 448

The SNR Margin tends to drop during the evening. If it drops to far from 5.1 you will re-sync and your downstream sync rate of 5728 will drop.

You appear to have had only 2 CRC errors (SFErr, I think), but this seems to be contradicted by

ES: 9764 0
SES: 24 0
UAS: 309 0

ES - Errored Seconds - number of seconds that have had CRC errors
SES - Severely Errored Seconds - after 10 seconds of ES we start counting SES
UAS - Unavailable Seconds - Seconds where we had no sync

I can't explain the contradiction.

Ok I think.Will see how it goes.

Thanks
