Example embodiments describe a controller comprising means for performing i) discovering a mapping between receive analogue to digital converters, RxADCs, of a full duplex node () and cable modems (----) connected to the full duplex node; and wherein the cable modems share a common communication bandwidth; and ii) determining, based on the mapping, sounding groups () by grouping cable modems (--) mapped to a same RxADC () into a respective sounding group (); and wherein a sounding group is indicative for an upper bound of possible interfering cable modems.

Full duplex cable communication

This invention relates to a method and apparatus for transmitting frequency shift key (FSK) data in packetized format. More particularly, the invention is directed to a method for using a new Real-Time Transport Protocol (RTP) payload type to transport FSK data used for voiceband data transmission outside of the voice RTP stream. This technique allows for data compression and reduces the possibility of packet loss for FSK data carried in-band.
