Static IP Settings
If you have been allocated a static IP by your DSL provider, please fill in the IP
Address, Subnet Mask and Gateway as provided. Your ADSL will not function if
a static IP is filled in when one has not been pre-assigned – please refer to your
DSL provider for further information.
ATM
VPI: Allows the Virtual Path Identifier to be set.
VCI:Allows the Virtual Channel Identifier to be set.
Service Category: This revision of firmware supports Unspecified Bit Rate (UBR),
Constant Bit Rate (CBR) and Variable Bit Rate (VBR-nrt).
Peak Cell Rate, Sustainable Cell Rate and Max Burst Size all apply to CBR
PPP (Advanced PPP Configuration)
Service Name: The service name of PPP is required by some ISPs, typically for PPPoE
connections. If your ISP does not specify a Service Name, please leave it blank.
Username: Enter the PPP user name (usually provided by the ISP).
Password: Enter the PPP password (usually provided by the ISP).
Disconnect Timeout: The Disconnect Timeout allows you to specify a period of time to
remain connected before disconnecting from the ISP. The default is 0, which means
never disconnect from the ISP. Other, traffic based timers can also be used.
MRU: Maximum Receive Unit indicates the maximum size of the PPP information field
that this device can receive. The default value is 1492 and is used in the beginning of the
PPP negotiation. In the normal negotiation, the peer will accept this MRU and will not
send packets with an information field larger than this value.
MTU: Maximum Transmission Unit indicates the largest physical packet size, measured
in bytes that a network can transmit. Any messages larger than the MTU are divided into
smaller packets before being sent. Trial and error is the only sure way of finding the
optimal MTU but it has been set to 1492 by default.
MSS: Maximum Segment Size is the largest size of data that TCP will send in a single IP
packet. When a connection is established between a LAN client and a host in the WAN
side, the LAN client and the WAN host will indicate their MSS during the TCP connection
hand-shake. The default value is 1432.
LCP Echo Interval: Allows the Link Control Protocol (LCP) Echo Interval to be set.
LCP Echo Maximum Consecutive Failure: Allows the LCP Echo consecutive failure
toleration to be set.
