ViewSonic WMG120, WMG80 manual ViewSonic Wireless Media Gateway

Collision avoidance. A network node characteristic for proactively detecting that it can transmit a signal without risking a collision.

Crossover cable. A special cable used for networking two computers without the use of a hub. Crossover cables may also be required for connecting a cable or DSL modem to a wireless gateway or access point. Instead of the signals transferring in parallel paths from one set of plugs to another, the signals "crossover." If an eight-wire cable was being used, for instance, the signal would start on pin one at one end of the cable and end up on pin eight at the other end. They "cross-over" from one side to the other.
