Asymmetric Connections
For a variety of environmental reasons (antenna placement, radio reflections, interference, etc.), asymmetric connections are sometimes formed between BreadCrumb devices. An asymmetric connection is a connection between two BreadCrumb devices in which each BreadCrumb device is transmitting at a different speed.
When an asymmetric connection is made, the BCAdmin operator will see two lines of the same color connecting two BreadCrumb devices. The speeds will be represented in the line styles as specified in the BCAdmin Line Styles Legend in the previous section. Transmission direction of each link is represented by motion of the dots or dashes comprising the lines. (11Mbps links are solid lines, so their direction in an asymmetric link is determined by elimination; its direction is simply the direction opposite the other link of the same color). The following figure illustrates an asymmetric link:

Redundant Connections
When two BreadCrumb devices have two radio channels in common, they often form redundant links between one another - that is, one connection on each channel. In these cases, lines of different colors will connect the two BreadCrumb boxes as in the following figure:
