  • Publication number: 20210105128
    Abstract: 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 (100) and cable modems (111-113, 121-123, 131-133, 141-143) 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 (152, 162) by grouping cable modems (111-131, 121-123) mapped to a same RxADC (151) into a respective sounding group (152); and wherein a sounding group is indicative for an upper bound of possible interfering cable modems.

  • Publication number: 20150350755
    Abstract: A manner of performing remote-node management, for example the management of ONUs in a PON. In that type of optical network, a management node such as an OLT determines that a management command is to be transmitted and also determines the management protocol associated with the management command. A management message is generated, the management message having a header with a device identifier field. When the management message is generated, the device identifier field is populated with a value indicating whether the management command is associated with a default protocol or with an alternate protocol. The value in the device identifier field may identify specific alternate protocols so that when the manage device, for example an ONU in a PON, received the management message it may be directed to an appropriate interface point.

  • Publication number: 20110142017
    Abstract: The preferred method involves segmenting the routable IP address space of a Cable Modem Termination System (CMTS) to identify clients requiring differentiated QoS by assigning IP addresses from reserved ranges. The IP addresses are assigned to home clients/the Wi-Fi AP and roaming users based on special DHCP options inserted by the Wi-Fi AP DHCP Proxy software on behalf the Wi-Fi AP and home client devices and roaming devices using the Wi-Fi AP. This creates potentially multiple service classes whereby IP addresses from the reserved ranges are included in traffic classifiers that cause packets to map to service flows which provide for differentiated QoS to the Wi-Fi AP owner, home clients and roaming users on the cable access network.

  • Publication number: 20050198391
    Abstract: 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.
