1. A network element to enable use of multiple active paths for time division multiplexing (TDM) traffic over a packet switched network, the network element comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the network element to
receive at least two copies of a replicated packet including TDM information via at least two paths through the packet switched network, the at least two copies of the replicated packet including at least a first copy of the replicated packet received via a first of the at least two paths, and a second copy of the replicated packet received via a second of the at least two paths,
select a copy of the replicated packet from among the at least two copies of the replicated packet,
input the selected copy of the replicated packet to a jitter buffer,
discard unselected ones of the at least two copies of the replicated packet, and
output the selected copy of the replicated packet from the jitter buffer to a TDM endpoint device.
