Description 
Notches 
RF interference reduction is disabled by default. 
Power Control 
This function minimizes the transmission power of each 
PowerGrid unit while maintaining data throughput performance. 
*Dynamic 
PSD Control 
The modem’s Ethernet port monitors the incoming traffic rate 
and subsequently calculates the transmission power required that 
permits this rate of transmission. 
The higher the incoming traffic rate, the greater the phy rate and 
transmission power required. The lower the rate, the lesser the 
phy rate and transmission power required.   
*  This feature has been developed to reduce the transmission power so as to 
cut the power consumption of the device and minimize the interference to 
other electronic devices in the vicinity. 
LLTD CONFIGURATION 
LLTD (Link Layer Topology Discovery) is a protocol supported by Windows Vista. 
LLTD enables applications to discover the topology of a network and includes 
optional QoS Extensions that applications can use to diagnose problems. 
Field 
Description 
Link Layer Topology 
Discovery (LLTD) 
When enabled, multicasting is limited to either IGMP or 
MLD Aware Multicast Syndication. 
MULTICAST CONFIGURATION 
IGMP (Internet Group Membership Protocol) and MLD (Multicast Listener 
Discovery) are protocols used by IP hosts to report their multicast group 
memberships to any neighboring multicast routers.
