AT-2973T
Adapter
The AT-2973T and AT-2973T/4 adapters include a 10/100/1000-Mbps
Ethernet MAC with both half-duplex and full-duplex capability and a 10/
100/1000-Mbps PHY. The transceiver is fully compatible with the IEEE
802.3 standard for auto-negotiation of speed and duplex mode.
The AT-2973T adapter operates at speeds of 10/100/1000T Mbps in
either full-duplex or half-duplex mode. This adapter has two twisted-pair
connectors and two LEDs, as shown in Figure 3 on page 21.
