Abstract
A method and apparatus for packetizing data framed as a TDM stream as an Ethernet packet. In an embodiment, the data is packetized into an Ethernet frame having a header which includes information which indicates an appropriate time at which to write the data into an outbound TDM stream.
Claims13
A method comprising:
- packetizing data framed as an inbound Time Division Multiplexing (TDM) stream as an Ethernet packet having a header which includes information which indicates an appropriate time at which to write the data into an outbound TDM stream.
A method comprising:
- accepting a first TDM stream into a switch having an Ethernet backplane, the first TDM stream including a plurality of TDM frames;
- writing a TDM frame into an Ethernet frame;
- sending the Ethernet frame to a destination of the TDM frame;
- extracting the TDM frame from the Ethernet frame;
- and
- sending a second TDM stream, including the TDM frame, from the switch.
3 more elements
A switch with an Ethernet backplane, comprising:
- a bus;
- and
- at least one line card connected to the bus, each line card including:
- circuitry to write TDM frames from an incoming TDM stream into Ethernet frames, circuitry to send the Ethernet frames to a destination of the TDM frames;
- circuitry to extract the TDM frames from the Ethernet frames once the Ethernet frames arrive at the destination of the TDM frames;
- and
- circuitry to send an outgoing TDM stream including the extracted TDM frames.
