  • Publication number: 20230412422
    Abstract: Interworking between different layer two (L2) medias using network tunnels is provided by receiving, at a virtual gateway network element (GNE), a packet from a first L2 media type network for transmission to a second L2 media type network under the control of a different entities, wherein the first and second L2 media type networks are incompatible for direct packet transmission; removing, at the virtual GNE, ethernet encapsulation from the packet; re-encapsulating, at a network device located between the virtual GNE and a packet network, the packet in a multi-protocol label switching (MPLS) encapsulation; forwarding, over the packet network, the packet from the network device to a digital communication channel (DCC) associated with the second L2 media type network; replacing, at the DCC, the MPLS encapsulation with a link access protocol (LAP) encapsulation; and transmitting the packet encapsulated with the LAP encapsulation to the second L2 media type network.

  • Patent number: 11239932
    Abstract: Techniques for emulating a time division multiplexed (TDM) circuit using a packet switched network are described. First and second packet nodes are installed in a communication network. The first TDM node and second TDM node form a first span in the TDM circuit. First and second fiber connections are disconnected from the first and second TDM nodes, and connected to the first and second packet nodes. A portion of TDM data transmission across the first span is emulated using a packet connection formed by the first packet node and the second packet node. The TDM data transmission includes transport overhead data, and the packet connection emulates the transport overhead data.
