Auto-negotiation

Communication speed (10 Mbps or

 

100 Mbps) and duplex mode (full or half)

 

can be determined through auto-

 

negotiation with the attached devices. The

 

IntelliJack attempts to negotiate the fastest

 

connection possible (100 Mbps full-

 

duplex).

 

The communication speed and duplex

 

mode can also be controlled using the

 

configuration management software.
