Since IP routers make forward or filter decisions based on the network layer IP address instead of the MAC hardware address MAC level broadcast frames are prevented from reaching unwanted destinations in the network When setting parameters for an external router configure a Static Route entry in any of the external routers that may have been specified as a Default Router or as a Gateway This implementation prevents other parties from discovering routes through eavesdropping The format of this entry varies among the various router vendors but is typically in the form of Destination Mask and Gateway where the Destination is the remote IP Subnet or host address and Gateway is the IP address of the modem on the same subnet as the external router Encapsulation for RFC 1483 Bridging Routing Most users select LLC which allows you to run multiple protocols over the VC An encapsulation header identifies the types of protocol being carried in the transmission for example IP VC MUX allows only one protocol to run over the VC The type of protocol must be negotiated between the modem and the service provider prior to the transmission Because there is only one protocol allowed the header is not required This configuration is normally setup by the service provider 66 Megabit Modem 400F User Manual Chapter 9 Technical Reference MANAGEMENT PROTOCOLS SNMP is used to configure system and bridge parameters to monitor statistic

BER means that on average one error occurs per 10 bits received Signal to Noise Ratio SNR is the ratio typically expressed in dB of the received signal power to the received noise power It is a measure of the quality of the transmission Margin SNR margin is the amount of degradation in SNR that the system can tolerate under the current conditions and still achieve 107 BER A margin of 6 dB for example means that the SNR can degrade by 6 dB and still provide a performance of 107 BER The Megabit Modem 400F have a margin configuration option that defaults to 3 dB but can be set anywhere between 0 to 15 dB Reach is the longest loop length that the system can support with a given margin Rate Adaptation With ADC s rate adaptive technology the Megabit Modem 400F can automatically startup or adjust to the fastest speed possible given the transmission distance and line conditions Or you can set the modem to a specific rate Reach Data Rate SNR Margin and Noise Environment The maximum transmission rate of the Megabit Modem 400F is determined by distance SNR margin and the condition of the line wire gauge condition noise environment The figure on page 73 shows the relationship between reach and data rate for a given set of conditions The plots can be used to determine the achievable reach at a given data rate or they may be used to determine the achievable data rates at a given distance In all cases except the no nois
