摘要：Communications systems and methods are directed to a novel communicationsplatform which employs a TDM bus, a TDM bus controller, a passive Ethernet bus, and acentralized Ethernet hub to provide for the communication of data, voice, and/or videosignals among a plurality of endpoint devices. The TDM bus controller provides aplurality of B- Channels on the TDM bus. The centralized Ethernet hub is coupled to theTDM bus controller via a control link. Each endpoint device is connected to at least oneof the passive Ethernet bus and the TDM bus. The centralized Ethernet hub operatesover the passive Ethernet bus to dynamically allocate one or more individual B-Channelsof a single B- Channel set amongst a group of endpoint devices, such as telephoneequipment, video communications equipment, processors, and/or computing devices. Thecentralized Ethernet hub provides a logical control channel to each endpoint device forcall establishment. Each endpoint device is coupled to the logical control channel over atleast one of a first path comprising the passive Ethernet bus and a second pathcomprising the TDM bus, the TDM bus controller, and the control link. The logicalcontrol channel executes B-channel seizure algorithms for establishment ofcommunications to and from selected endpoint devices.
