Just quickly want to state the WoR episode on the CCT outright states that if one of the four main towers is offline, then the network falls with it. The thing is that it kind of makes sense, since the CCT is based on radio. The main towers likely broadcast the largest radius of radio waves with the relay towers helping to fill in the gaps. The village in "The Next Step" stated that their signal with the Mistral CCT tower was already weak, and judging from the map seen in "Remembrance" is southwest of Lake Matsu. Argus's CCT tower is shown to have a much smaller radius, only reaching to the edge of the nearby forest.

Given that Argus is in northwestern Anima, the closest main CCT towers would've been in Mistral and Vale. Atlas's main CCT tower would be too far out of range for the Argus relay CCT to connect to it.
