I was not aware of the 600' limitation. Is this just limiting intercom functionality or will no stations be able to use CO lines?

The building's size is 60x60 and includes a second floor. The telephone room is near the rear corner. Looks like its time to break out the blueprints to see if its even possible to use this system.
