a. Network Unit (NU)
The NU is the head end for the QUATRA EVO system. The signal sources (one for each
port/operator) are connected to the NU. Then they are digitized and distributed over two
Category cables to each CU, along with power (PoE) for the CU.
QUATRA EVO NU
Note
Only cellular signals may be connected to the donor ports. Other types of radio signals will not
work and may damage the system.
The NU has two (2) N-type(f) RF ports on the top for operator donor signals.
There are two (2) SMA(f) ports on the top of the NU. One functions as the external antenna
connection for the unit’s internal cellular modem (CELL), and the other is for GPS. The GPS
port is unused (future functionality).
