I was recently asked an intriguing question. Are point-to-point WAN
circuits (T1 frame relay, T1 dedicated, etc.) full-duplex? In that data is
transmitted and received at the same time. My answer was yes, although I
never thought of it as full-duplex. Usually when someone says full-duplex I
think of LAN topologies and switches, but not WAN. Interesting.
So, are most WAN topologies full-duplex? I would think point-to-point
topologies are, but multipoint topologies may not.
Thoughts.
