the present invention is an access control system such as a telephone entry system wherein tenant codes are selectively displayed and therefore , tenant codes that are not selected for display are not listed in a system tenant code directory . tenants may control who knows that they live in the building and , therefore , control who can get in touch with them . thus , tenants may avoid having their name displayed on the access control system . tenants still may have a unique number in the index without having their name displayed , keeping their name unlisted .
