7.1 Noise Test
The front-end noise will be monitored by reading the noise power value from the reverse
channels in the RAN SIF module belonging to the tenant-sector being analyzed. The in-band
noise power (N) and total signal power (S+N) will be measured and analyzed in the SIF using
an FFT analysis, as follows:
The RCM software will generate faults if the integrated power levels are below the specified
thresholds.
7.2 RAN Down Converter (RDC) Tone Test
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 Hub Up Converter (HUC) Tone Test
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 –70 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 “SNMP Agent and Fault Isolation Guide” for details.
