Abstract
A network element includes at least two Time Division Multiplexing (TDM) modules each including a TDM client interface, TDM processing circuitry, and circuit emulation circuitry; and a packet switch fabric connected to the at least two TDM modules and configured to output a packet interface, wherein a protected TDM service through the at least two TDM modules is provided as a single packetized TDM stream via the packet interface from the packet switch fabric.
Claims20
A network element comprising:
- at least two Time Division Multiplexing (TDM) modules each including a TDM client interface, TDM processing circuitry, and circuit emulation circuitry;
- and
- a packet switch fabric connected to the at least two TDM modules and configured to output a packet interface,
- wherein a protected TDM service through the at least two TDM modules is provided as a single packetized TDM stream via the packet interface from the packet switch fabric.

An apparatus comprising:
- Time Division Multiplexing (TDM) processing circuitry configured to interface TDM clients;
- circuit emulation circuitry connected to the TDM processing circuitry and configured to packetize TDM traffic streams;
- and
- a packet switch fabric connected to the circuit emulation circuitry and configured to output a packet interface,
- wherein a protected TDM service through the TDM processing circuitry is provided as a single packetized TDM stream via the packet interface from the packet switch fabric.
2 more elements
A method comprising:
- receiving a protected Time Division Multiplexing (TDM) client that includes a working line and a protection line;
- processing each of the working line and the protection line for the protected TDM client;
- packetizing one or both of the working line and the protection line;
- and
- outputting a single packetized TDM stream based on the working line via a packet interface from a packet switch fabric.
