Setting this to a value 0-9 tells the modem to save its current configuration into one of ten onboard memory slots. Because it is a command-only object where a Get always returns 0 rather than reflecting the last slot used, it is only meaningful as a write, letting an admin keep several named configurations, such as one per satellite or carrier plan, on the same box for quick recall. Setting cdm570ConfigurationSave=3 stores the current settings into slot 3, which could later be recalled with cdm570ConfigurationLoad=3 to switch back to that carrier profile.
