Thank you very much @tonygibbs16 Btw I found modem that has such info in datasheet: ADSL (G.992.1) Annex A, B ftp://ftp.zyxel.com/VMG3925-B30C/datasheet/VMG3925-B30C_1.pdf You see sometimes they shows full spec info!

Thank you @tonygibbs16 But really how to ask manufacturer? 

Actually why we trying to guess the information. how to ask manufacturer?

Hello and thanks for reply @tonygibbs16 Modem can support both annex A and B for ADSL2 (G.992.3) but only Annex A for ADSL1 (G.992.1). Im looking only for ADSL1 (G.992.1) Annex B. Early models supporting ADSL Annex B always had that in title - for example ASUS DSL-N55U Annex B. That was really important to mention it in…

Every pdf mention that model supporting G.992.1 (G.dmt). no info about annex. seems if nothing mentioned about annex so model supports only annex A by default? or maybe both A and B?

Thanks @tonygibbs16 for your answer. But how did you find any of this has annex B? I opened every item and check ftp pdfs - no info about annex at all. Or maybe every model has annex A and B modifications?
