Performance
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.
