1. A line module configured to provide a protected transponded service, the line module comprising:

  • a plurality of ports;

    switch interface circuitry communicatively coupled to a switch module;

    interface circuitry communicatively coupled to the plurality of ports and the switch interface circuitry, wherein the interface circuitry comprises a cross-point switch between the plurality of ports and the switch interface circuitry;

    wherein bandwidth of the plurality of ports is greater than bandwidth of the switch interface circuitry to the switch module; and

    wherein the protected transponded service is configured between the plurality of ports directly via the interface circuitry and is selectively routed to the switch module via the switch interface circuitry for restoration thereof, responsive to a failure.
