A Managed Access System (MAS) at a correctional facility includes a local database for storing data relevant to authorized and unauthorized cellular communications activity, and a graphical user interface (GUI) for accessing the data and adjusting MAS settings. The local database is capable of synchronization with a remote database at a central facility. The central facility may include a processing system having code for monitoring the MAS and, in some configurations, additional MASs located at other correctional facilities. The code and the remote database may be configured to interface with the local databases at these other correctional facilities. A synchronization operation between the remote database and one or more local databases may be performed by a user with appropriate permissions. In this manner, an authorized user at the central facility can access the different MAS systems at different correctional facilities and manage the data or settings.
