Can D-ATIS be obtained using and what is the primary difference between
 1. D-ATIS (Frequency given in Airport diagram(jeppesen)) ?.
 2. 2.Using AOC function and obtaining D-ATIS using DSP (SITA or ARINC))?.

1.Example: if you look at EDDF (Frankfurt Main) D-ATIS Departure Frequency is 118.730Mhz, should we enter this frequency in RMP3 of Airbus A320 and obtain D-ATIS message using MCDU ?.(I haven't been able to find any videos of pilots obtaining messages using this method)

2.ACARS is a network that is made possible by 2 Major DSP (Datalink Service Provider) SITA and ARINC and Airline partners with either of the 2 to provide them with services, one of them being Weather.

Which one to use to obtain D-ATIS ?.
