Page 12: Theory Of Operation
The ET100/G64 utilizes both Ethernet Bridging and HDLC encapsulation to provide a connection between LANs over bit stream architectures. The LAN side of the ET100/G64 receives an Ethernet packet and examines its destination MAC address. If it knows the MAC is on the local network then it simply drops the packet. -

When this feature is disabled, all frames are passed transparently. In this configuration, the ET100/G64 acts as a repeater. When the filter is enabled, frame destinations are tested against the internal MAC address table. Filtering enabled is the normal selection for Bridging but is usually disabled when connecting to a switching HUB. - Page 15 ET100/G64 LAN-WAN Bridge The next example connects the pair of ET100/G64 bridge units to existing G.703 64K co-directional transmission equipment which already supplies the clock to the tributary equipment.
