1.0 SPECIFICATIONS
1.1 Technical Specifications
100 or 10 Mb/s per port, auto-sensing for speed. DS8016 hubs support
two traffic domains, one at 100Mb/s and one at 10Mb/s, have sixteen RJ- 45
ports, and are stackable up to 3 units high operating as one repeater. In
addition , a Media Independent Interface (MII) port is provided per unit
(except on -R “reverse” models)
Performance
When a port is operating at 100Mb/s:
Data Rate: 100 Mb/s
PDV (Path Delay Value) : 80BT, exceeds Class II
When a port is operating at 10Mb/s: Data Rate = 10 Mb/s
Partitioning: Enforced after 63 consecutive collisions
Auto-reconnect: Occurs after one packet of error-free reception
Network Standards
100Mb: Ethernet IEEE 802.3u , 100BASE-TX
10Mb: Ethernet IEEE 802.3, 10BASE-T
