Notes:
The DECmau 900TL has speed detect, which ensures the integrity of the network. At startup, a MAU determines the ring speed based on the speed settings of the majority of the stations on the ring and the Ring Out port. In a hub, the MAU then connects to the appropriate ring in the hub. After startup, speed detect prevents stations with the wrong speed setting from connecting to the net- work.
Network management can override any of the MAU's factory default settings.
