This table displays channel content obtained from SC-QAM channels and provides Upstream/Downstream filtering along with Sorting and Show/Hide columns. Columns can be resized by dragging the vertical lines between columns. Thresholding values are configured with an assigned Proactive Profile, which uses ingested hierarchy and modem assignment to determine which profile is for which modem.
NOTE: DOCSIS 3.1 channels appear
on the OFDM/A screen. Refer to OFDM/A tab
for OFDM/A channel information.
The SC-QAM table includes the following
columns:
- Row Number — Row number of the upstream and downstream channels.
- Channel Name — Channel associated with the MAC Address. Some channels have links that direct you to different NXT applications.
- Partial Service — Displays the reason a CM is currently experiencing partial service with a bonding group using this channel. A value of none indicates no partial service.
- Frequency (MHz) — Center frequency associated with the MAC Address.
- Channel Width (MHz) — Bandwidth of the channel. The channel width is configured by the administrator and represented in MHz. The larger the channel bandwidth, the greater its data carrying capacity.
- Modulation — The configured modulation type used to transmit data. Possible upstream values include Quadrature Phase Shift Keying (QPSK), and Quadrature Amplitude Modulation (QAM 8, QAM 16, QAM 32, QAM 64, and QAM 128). Possible downstream values include QAM64 or QAM256.
- Channel Type — Indicates the mode of the upstream connection between the CMTS and the cable modem. Possible values for this fact are TDMA, ATDMA, and SCDMA.
- Timing Offset (μS) — A measure of the time required for a signal to propagate in the network between the CMTS and cable modem.
- Configured Power (dBmV) — An administrator set value that indicates the desired signal level that should be targeted for transmitting and receiving.
The SC-QAM table also displays data for the KPIs. Refer to SC-QAM parameters for definitions of the KPIs.
