Theory of Operation
ONline Ethernet 24-Port 10BASE-T Modules incorporate repeaters and
twisted pair transceivers that receive and restore amplitude to incoming
signals. 24-Port Module repeaters restore phase and frequency.
Repeated signals:
Synchronize to the system clock
Enter on the TriChannel® backplane of the ONline System
Concentrator.
Outgoing signals from the TriChannel backplane are:
Sent directly to transceivers
Transmitted to twisted pair link segments by the transceivers
