Just "upgraded" to IPDSL, how to these stats look

Today they did the switch from old DSL to IPDSL it has been up a couple of hours, how are the stats below? Also if I buy (eBay) another modem (Motorola NVG510) as a spare, what if anything do I have to provision to use it?

Downstream Sync Rate (kbps) 3000
Upstream Sync Rate (kbps) 509
Modulation ADSL2+
Data Path Interleaved

IPv4 Statistics
Transmit Packets 130664
Transmit Errors 0
Transmit Discards 0

Downstream and Upstream Statistics
Downstream Upstream
SN Margin (dB) 6.1 16.0
Line Attenuation (dB) 54.0 30.3
Output Power(dBm) 16.9 7.3
Errored Seconds 1 0
Loss of Signal 0 0
Loss of Frame 0 0
FEC Errors 913 0
CRC Errors 2 0

That looks marginal. Assuming "AT&T U-verse HSI Pro", I would expect the sync rates to be: 3008/512.

I haven't enough ADSL2+ experience to comment on the combination of SNR/Attenuation you are showing, but 6.1 dB SNR is marginal. If you are not seeing problems, the Interleaved profile is working.

Also if I buy (eBay) another modem (Motorola NVG510) as a spare, what if anything do I have to provision to use it?

I have no personal experience, but a quick Internet search suggests that a used NVG510 should work. But you probably should wait for more expert advice.

Generally the MOT modem/router is the one they send out for IP-DSL. at least in the Ohio region.

If you're using the NVG510 or 2210-01-1ATT now, the spare NVG510 will work just fine - no provisioning needed. Just plug it in.

As for your stats, like NormanS said, they're marginal. my SN margin is similar on the 18Mbps plan - I never lose sync, but there are a lot of FEC errors and some CRC. You'll probably not notice any issues, but you won't be able to get any service above 3Mbps.
