FirstClass Synchronization Services (FCSS) provides SyncML and Activesync interfaces for FirstClass systems. SyncML and Activesync are industry standard protocols supported by a wide variety of handheld devices and desktop applications as a way to synchronize important user data between a server and those devices/applications. FCSS must be installed on your FirstClass system by your administrator. With FCSS installed, you can synchronize your FirstClass calendar events, contacts, and tasks with up to four remote devices and applications. These can include mobile phones, smartphones, personal digital assistants, and standards-based email clients. Your SyncML or Activesync enabled device communicates with FCSS by sending commands through a standard HTTP data connection over a wired or wireless data network.
