A view around flow indicator comprising a housing, a turbine wheel, a cylinder, and a visually perceptible pattern on the outside surface of the cylinder is disclosed. A single Virtual Routing and Forwarding device is associated with a single customer site. Light emitted from the LED that falls outside of the numerical aperture of the waveguide leaks out of the waveguide, but is reflected back to the waveguide by the reflector. The CAM cell further includes a match circuit coupled to one of the complementary data nodes of the latch.
