Building a Bigger Pipe: Inverse Multiplexing for Transparent Ethernet Bridging over Bonded T1/E1s

This paper proposes a solution for extending the availability of transparent high-speed Ethernet by re-using the existing T1/E1 TDM network. By employing inverse multiplexing technology with support for jumbo Ethernet frames, service providers can use bonded T1/E1 circuits to transparently backhaul Ethernet from remote cell sites and IPDSLAMs. This paper covers the rationale, protocols and key features that an Inverse Multiplexer (Inverse Mux) must support in order to close the current capabilities gaps in carrier and provider networks.
