Name Standard Annex info
Full-rate ADSl G.992.1 A (above POTS), B (above ISDN), C (same cable), J, L, M. The annexes in this specification seem to be the same for all G.992.x standards.
G.992.2 Annex H This standard does exist, for what purpose I do not know.
G.lite G.992.2
ADSL2 G.992.3 See full list on Wikipedia. Relevant annexes are A, B, I, J, L, M. Wikipedia
ADSL2+ G.992.5 Only ever seen A, B, M and J
---
VDSL G.993.1 Annex A (plan 998), Annex B (plan 997), Annex C (rare, only used in Sweden). These seem to be different to the annexes set by G.992.1 and related ADSL standards.
VDSL2 G.993.2 Annex A is the bandplan for North America, B for Europe and C for Japan. Not sure why these are different to VDSL1 standard.

Stepper driver current

Can be adjusted manually with Vref, or digitally (for marlin in Configuration_adv.h.

Calculating

Imax -> Maximum current per phase. This is often the value on the motor datasheets.

Irms -> Root mean square current, or average current.
