Since the introduction of Cablelabs DOCSIS 3.1 specifications, QAM channels have been sharing the upstream spectrum with OFDMA channels. Through Proactive Network Maintenance (PNM), DOCSIS 3.1 specifications leverage CMTS and cable modem features and capabilities to enable measurement and reporting of network conditions and their effects. These measurements include FEC statistics (BER) as measured by the CMTS on upstream OFDMA channels. Accordingly, the scope of this test was not broadened to cover OFDMA channels. Instead, the reader is referred to the DOCSIS 3.1 specifications.
