All parameters related to OFDM and OFDMA are listed here. Refer to Key performance indicators for definitions of the following parameters:
Downstream Power (OFDM):
- Cable Modem > Average Rx Power (dBmV)
- Network > Abs Rx Power Avg (dBmV)
- Network > Rel Rx Power Avg (dBmV)
Downstream Noise (OFDM):
- Mean MER (dB)
- MER Deviation (dB)
- MER Percentile Value (dB)
Downstream FEC (OFDM):
- PLC CER (%)
- NCP CER (%)
- CCER+CER (%)
- CER (%)
Downstream Partial Service (OFDM):
- Partial Service
Upstream Power (OFDMA):
- Cable Modem >Tx Power (dBmV)
- Cable Modem > Average Rx Power (dBmV)
- Cable Modem > Attenuation
- Network > Abs Attenuation Avg (dB)
- Network > Rel Attenuation Avg (dB)
Upstream Noise (OFDMA):
- Mean MER (dB)
- MER Deviation (dB)
- MER Percentile Value (dB)
Upstream FEC (OFDMA):
- CCER+CER (%)
- CER (%)
Upstream Partial Service (OFDMA):
- Partial Service
- T3 Errors OFDMA
- T4 Errors OFDMA
IUC Efficiency (OFDMA):
- IUC MHz Efficiency (Mbps/ MHz)
- IUC Usage Efficiency (%)
NOTE: Data displayed in the IUC columns
in table are per-IUC, and not per-modem like in the other columns.
Multiple rows can exist for each modem/OFDMA channel because multiple IUCs can be
associated with each modem/OFDMA channel.
