The Primary Hub provides the connection to wireless operators' or public safety source(s), converts RF signals to optical, and connects via fiber to either Secondary Hubs or Remotes. The Primary Hub also provides Web GUI for DAS configuration and GUI/SNMP for status monitoring. Alarming is provided via relays. The Primary Hub features a unique internal matrix that provides flexibility for routing supported wireless services within a system deployment. This allows specific operators or frequencies to be routed to the entire system or to designated parts of the system, depending on requirements. A UNItivity 5000 system can range from a single Primary Hub and Remote (a 1-1 configuration) to multiple layers consisting of a Primary Hub, eight connected Secondary Hubs, and 64 Remotes (a 1-8-64 configuration). The Primary Hub is modular and supports up to four Service Modules and up to eight Optical Modules or Transport Modules.
