This controls creation, modification, and deletion of rows in the general CAS configuration table, covering the tone-power, cadence, and digit-collection-timer objects above, with the system default profile at index 1 permanently protected from modification or deletion. This is the same protected-default pattern used throughout the CAS-IF-EXT-MIB, ensuring that even if an admin's custom general-configuration profile, covering things like twist levels or digit-map timers, is broken, a known-working baseline profile always remains available at index 1. An admin tuning tone power and cadence settings for a new trunk type would create a new profile at index 2 rather than modify the protected default, preserving a safe fallback configuration.
