ORU-N28-Z01-2

Single Band ORU supports both LTE and 5G NR for Band n28 up to 2T4R
Four antenna ports shared across the n28 band
Supports 2T4R for Band n28, with a maximum output power of 40 watts per port
Two 10G CPRI ports for Distributed Unit (DU) communication
3GPP Release 15
AISG 2.0 RET control, upgradeable to AISG 3.0

Overview

CCI's n28 Band 4G and 5G enabled ORAN Radio Unit (ORU) is compliant with the ORAN interface specifications supporting the 7.2x split network configuration and supports Open Radio Access Network (ORAN) interface. The RU comes equipped with two 10G CPRI optical interface port to communicate with the Distributed Unit (DU) for fronthaul network interfacing. This compact, multi-band, multi-technology ORU provides a standard open interface to other ORAN compliant vendor CU/DU, EMS, 5GC, and OSS products. Furthermore, it also supports the specifications set out in 3GPP Release 15.

LED Overlay

“ALM” LED off, no alarm, turns Red if alarm is generated.
“OPER” LED off, when booting or power is off, turns Green if radio is on and initialization is complete.
“ACT” LED off, Tx channel is disabled, turns Green if channel is enabled.
“VSWR” LED off, no Mismatch alarm, turns Red if mismatch alarm is generated.
“OPT1" LED off, CPRI link is down, tuns Green if CPRI link is up.
"OPT2” LED off, CPRI link is down, tuns Green if CPRI link is up.

Main Function Features	Remote Electrical Tilt	Based on AISG protocol and o-ran-ald.yang model to communication with the external RET equipment
	Voltage Standing Wave Ratio Detection	Support VSWR detection for each RF port to check antenna connectivity, there are two types of VSWR alarms: Minor VSWR alarm, RU will keep radiating, the service would be degraded. Critical VSWR alarm, RU would shut off corresponding RF branch.
	External Alarm	Support external device supervision, RU would monitor external alarm port state and send notification to O-RU controller based on o-ran-externalio.yang model when input port state is changed (circuit from open to closed or circuit from closed to open). RU can also report external alarm to O-RU controller once input port circuit from open to closed via customized fault.
	Cascading	Not Supported
	Security	Support TPM2.0
	PAP	Support PA protection functions, including the scenario: SFP port abnormal disconnect External Power supply abnormal Abnormal signal generated
