This object is used to create a new row or modify or delete an existing row in this table. A profile is activated by setting this object to `active'. When `active' is set, the system will validate the profile. Each entry must be internally consistent, the Stop Tone must be greater than the Start Tone. Each entry must also be externally consistent, all entries indexed by a specific profile must not overlap. Validation of the profile will check both internal and external consistency. None of the columns in this row may be modified while the row is in the 'active' state. Before a profile can be deleted or taken out of service, (by setting this object to `destroy' or `notInService') it must be first unreferenced from all associated lines.
