The size (number of sub-carriers) of each of the channels can be configured according to embodiments based on the available spectrum and/or other requirements (e.g., EPoC emission requirements, existing services, etc.). Further, within each channel, individual sub-carriers can be configured independently, including turning each sub-carrier on/off and/or specifying the symbol bit loading for the sub-carrier independently of other sub-carriers in the channel.

9553744 01/24/2017 Prodan, Richard Stephen (Niwot, CO, US) Laubach, Mark Edward (Redwood City, CA, US) Montreuil, Leo (Atlanta, GA, US) A communication device includes a communication interface and a processor configured to generate, transmit, receive, and process signals. The communication device generates orthogonal frequency division multiplexing (OFDM) frame(s) that include a two-dimensional (2D) start burst marker (BM), a data payload, and a 2D stop BM, and transmits the OFDM frame(s) to another communication device. Alternatively, the communication device receives OFDM frame(s) that include a 2D start BM and a 2D stop BM, and then identifies a data payload within those OFDM frame(s) based on the 2D start burst marker and a 2D stop BM. The 2D start and stop BMs are based on predetermined sequences having particular formats based on corresponding 2D sub-carrier and OFDM/A frame based structure. A receiver communication device then detects the 2D start BM and 2D stop BM within the received OFDM frame(s) based on knowledge of these predetermined sequences and particular formats.

The PHY link signaling channel is embedded within the same multi-carrier channel as the data and enables PHY link up between the network termination modem and cable modem without involvement of higher layers (e.g., MAC). The PHY link signaling channel can be implemented in the downstream (from the network termination modem to the cable modem(s)) or in the upstream from a cable modem to the network termination modem. Embodiments are applicable to any known cable network, and particularly to cable networks implementing the DOCSIS and EPoC standards.

The diagnostic analyzer can be configured to generate sample captures of the signal based on any desired parameter(s), condition(s), and/or trigger(s).
