forgive any confusion
com 1 for ATC
Com 2 for company "guard" freq if ACARS not working (acars is used in lieu of company guard when ACARS is working normally)
if ACARS working ( a data link with its own vhf radio) then 121.5 in com 2
ACARS could be used for data link messages from company or getting ATIS in text form.
certainly when text atis not available, we would use com 2 for audio atis.
AND if you wanted to get fancy, ACARS dedicated number 3 radio could be tuned to any normal VHF com freq, but you would lose text capability.
again forgive any confusion.
