SVPE48

  • The SVPEx8 series Interface Converter is an Ethernet extension device utilizing TDM telecom infrastructure (the telecom network of E1s/PDH/SDH carrying E1s). It converts the Ethernet data into E1 frame format for transmission over the existing TDM (E1) links and then re-converts the E1 back into Ethernet data at far-end terminal, to bridge two Ethernet LANs over the existing E1-based telecom network. The device can effectively utilize the redundant bandwidth of telecom operators’ existing TDM network to transport Ethernet data with low investment.
