Technical Reference for ZyXEL omni.net series

phone number 's'.

In cases when the omni.net is unable to distinguish which POTS port to route the incoming voice call to, your ISDN TA will alert both POTS ports by default [ATS120.2=0], until the first available port answers. Otherwise [ATS120.2=0], an ambiguity resolution bit (Bit 5 of S84, or &Ln) can be used to determine the path.
