shipped with the correct Tone Detector circuit packs for your country. If
you have TN420C you must use A-law. If you have TN748 or TN756 you
must use Mu-law. If you have TN2182, then your companding mode is
dictated by your local practices. Administering the correct companding
mode will turn off any red lights on these circuit packs or on the tone-clock
boards (for example TN780).

for a list of the country codes.
