The SC-QAM tab shows the modem's upstream and downstream parameters. (see below)

Modem Upstream/Downstream (US/DS) parameters available in the SC-QAM view are as follows:

Freq (All US/DS channel frequencies)
Tx Pwr (upstream power levels)
Rx Pwr (downstream power levels)
MER (downstream modulation error ratio)
SNR (US/DS signal to noise ratio)
CER% (percentage of US/DS codewords received on the channel that had unrecoverable errors)
CCER% (percentage of US/DS codewords received on the channel that had recoverable errors)

Click the OFDM/A tab to view DOCSIS 3.1 modem parameters.

Only the downstream OFDM carrier is operational in the Trinidad market. No OFDM/A exist at this time.

The following downstream parameters are available on the OFDM tab view:

Rx Pwr (downstream power levels)
MER (downstream modulation error ratio)
SNR (US/DS signal to noise ratio)
CER% (percentage of US/DS codewords received on the channel that had unrecoverable errors)
CCER% (percentage of US/DS codewords received on the channel that had recoverable errors)
