IR-ETH/QH Connector 

B-1 

The IR-ETH/QH interface module includes a high performance self-learning Fast 
Ethernet bridge, which is connected to the LAN via a single 10BaseT or 100BaseT 
port, operating in full duplex and providing offer simple and cost-effective 
interconnection between 10/100BaseT LANs via VDSL links. The IR-ETH/QH 
interface module also supports IEEE 802.1/Q frames, enabling VLAN applications. 
The module automatically learns MAC addresses of the LAN to which it is 
connected. Its LAN table stores up to 1,000 addresses with 5-minute automatic 
aging. 
Filtering and forwarding is performed at the maximum theoretical rate of 
150,000 packets per second (wire speed). The buffer with 1 Mb DRAM can hold 

170 frames with a throughput latency of one frame. The forwarding of the 
broadcast and multicast messages from LAN to WAN can be disabled.
