2.1.1.3 RIM/RIM-M (RF Interface Module)
The RIM/RIM-M module is a service specific RF conditioning module (up to 12 are installed in an HEU chassis) which interfaces
to the RF signal source. Each RIM supports both Simplex and Duplex RF connectors. LEDs provide status indications on signal
level and module operation.
Note: RIM-M modules support MIMO services (e.g.700 MHz LTE, AWS).
