• Integrated power for 24.6 to 39.6 MHz (dBm) using lowest 33% of the bins (Noise
Power)
• Integrated power for 24.6 to 39.6 MHz (dBm) using lowest 100% of the bins (Signal
Plus Noise Power)
The RCM software will generate faults if the integrated power levels are below the specified
thresholds.
7.2 RDC Tone
The RDC Tone will be enabled at all times, unless explicitly disabled via the RDC MIB. Its
frequency corresponds to the first channel in the band set for that tenant-sector. Additional
requirements are:
• The RDC tone level is –80 dBm referenced to the front end antenna port of the RAN
• The RDC Tone is available on the primary and diversity paths
In the RAN, power measurements are taken at the reverse channels of the RAN SIF belonging
to each tenant-sector. In the Hub, these power measurements are taken at the BIM. These
power measurements are performed continuously on a one-minute poll rate and are compared
to specified threshold values.
• If the test tone is not detected in the RAN SIF, then the RDC is reported as faulting.
See troubleshooting guide for details.
7.3 HUC Tone
The HUC tone will be enabled at all times, unless explicitly disabled via the HUC MIB. Its
frequency corresponds to the last channel in the band set for that tenant-sector. Additional
requirements are:
• The HUC tone level is –60 dBm relative to the antenna port at the RAN.
• If the test tone is not detected at the BIM, it and the HUC are reported as faulting.
• See troubleshooting guide for details.
8 PA OVERPOWER PROTECTION
PA Overpower Protection (POP) is a software function that prevents damage to the PA as well
as preventing the PA from exceeding FCC spurious output limits.
POP measures the PA Output Power once per second from the RUC/PA MIB. If the PA
Output Power exceeds a determined threshold, then POP will deactivate the FGC process for
the tenant-sector in question, add attenuation to the RUC, and set a fault in the FGC MIB.
Once the PA Output Power returns to a value that is less than a determined threshold, then the
POP fault will be cleared and normal operation will resume. See troubleshooting guide for
details.
