VC 1 Configuration
VPI This setting allows you to change your VPI (Virtual Path Indicator) value for a
particular VC, which is defined by your Service Provider.
VCI This setting allows you to change your VCI (Virtual Channel Indicator) value for a
particular VC, which is defined by your Service Provider.
PCR Factory Default = 100%
Peak Cell Rate (PCR)-The maximum rate at which cells can be transmitted across a
virtual circuit, specified in cells per second and defined by the interval between the
transmission of the last bit of one cell and the first bit of the next.
This value is a percentage of the current data rate.
100 allows this VC to use 100% of the available bandwidth.
80 allows this VC to use 80% of the available bandwidth.
QoS Quality of Service, which is determined by your Service Provider.
CBR = Constant Bit Rate
UBR = Unspecified Bit Rate
VBR = Variable Bit Rate
Protocol The Protocol for each VC, which is specified by your Service Provider.
PPPoA = Point to Point Protocol over ATM (Asynchronous Transfer Mode)
PPPoE = Point to Point Protocol over Ethernet
Bridge = Bridge Protocol
Classical IPoA = Internet Protocol over ATM (Asynchronous Transfer Mode). This
is an ATM encapsulation of the IP protocol.
Status The protocol status.
VC x PPPoE Settings
IP Address Displays the IP network address that your modem is on.
Gateway Displays the router IP Gateway address
DNS Primary Provided by your Service Provider
DNS Secondary Provided by your Service Provider
MRU Negotiation Factory Default = DISABLED
If ENABLED, the Maximum Received Unit (MRU) would enforce MRU
negotiations. (NOTE: enable this option only at your Internet Service Provider’s
request.)
LCP Echo Disable Factory Default = Enable
If checked, this option will disable the modem LCP Echo transmissions.
LCP Echo Failures Indicates number of continuous LCP echo non-responses received before the PPP
session is terminated.
LCP Echo Retry Duration Indicates the interval between LCP Echo transmissions with responses.
LCP Echo Retry Duration Indicates the interval between LCP. Echo after no response.
Tunneling
Factory Default = ENABLE
If ENABLED, this option allows PPP traffic to be bridged to the WAN. This feature
allows you to use a PPPoE shim on the host computer to connect to the Internet
Service Provider, by bypassing the Router’s capability to do this.
NOTE: The values for IP Address, Gateway, DNS Primary, and DNS Secondary are all “Override of the value
obtained from the PPP connection,” They default to “0.0.0.0,” in which case the override is ignored. Westell
recommends that you do not change these values unless you are instructed by the Internet Service Provider.
