6. How do I find out about DSL line errors?
The easiest way to tell is enter console mode and check out the features under the bsp menu. Typing bsp perf will give you the physical error information FEC (forward error correction), CRC (cyclic redundancy check) and HEC (any ideas?) parameters of your circuit. Large and rapidly increasing totals for these values are bad. These counters should climb up slowly under normal circumstances. The main source of evil are CRC errors ie uncorrected errors which resulted in a retry. Below is some sample output from a AAM6000EV.
============= NEAR END ===========
------- INTERLEAVED CHANNEL ------
FEC : 24919
CRC : 33
HEC : 29
============= FAR END ============
------- INTERLEAVED CHANNEL ------
FEC : 19
CRC : 0
HEC : 0
Another useful bit of information on the physical circuit, is from the bsp channel command. This output shows you the signal strength info and the negotiated line rates. Here is some sample output from my DSL line.
Operation Mode Seletected : G.DMT
Downstream Capacity Occupation : 98 %
Downstream Noise Margin : 5.5 dB
Downstream Attenuation : 34 dB
Downstream Output Power : 19.5 dBm
Upstream Capacity Occupation : 95 %
Upstream Noise Margin : 12 dB
Upstream Attenuation : 26 dB
Upstream Output Power : 12 dBm

I can't seem to find anywhere that will report ATM statistics. The portcli menu's should report ATM details, but the report tools of "portcli errors", "portcli portload", "portcli stats" and "portcli show" all return zero's under ver63 (2001). Perhaps ASUS didn't think this reporting was useful. At any rate, the above details should give you a leg to stand on if you have a line quality issue with your local DSL provider.
