1.7.4Synchronous Interface (SIF) ModuleThe Synchronous Interface (SIF) Module provides the optical interface between the Hub and the RAN. This interface provides for exchange of digitized RF signal information and 10BaseT Ethernet command and control information. Each RAN can have up to two SIFs, each handling two bands with diversity receive paths.
