Network Chassis Unit or NCU
The Network Chassis Unit is the main controller of the RFS, providing external
network interfaces and the baseband network processing for the ACUs and
RFUs. The NCU also is the interface between the RFS and the
telecommunications switching entities. The NCU is 7” high x 19” wide x 13”
deep, powered by 120VAC, and rack mounted. Connections are CAT 5 (RJ45)
except power, an EIA-232 interface, two BNC ports, and an SMB port for GPS
antenna connection. The NCU connects up to 8 ACUs, a WLAN, and in iDEN
installations, an iSC (integrated Site Controller). An RFS with a single NCU
provides a coverage area of up to 2 million square feet.
