: Virtual Channel Identifier. The valid range for the VCI is 1 to 65635 (0 to 31 is reserved for local
management of ATM traffic).
Select the Quality of Service types for this Virtual Circuit. The ATM QoS types include
CBR(Constant Bit Rate), VBR(Variable Bit Rate) and UBR (Unspecified Bit Rate). These QoS types
are all controlled by the parameters specified below, including PCR, SCR, and MBS.
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter
may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a
maximum speed of 832 Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed
because it is dependent on the line speed.
Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can be sent
at the peak rate, and a parameter for burst-type traffic. SCR may not be greater than the PCR; the
system default is 0 cells/sec.
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After
MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more
cells (up to the MBS) can be sent at the PCR again.
is for connections that support constant rates of data transfer. The only parameter you need to
worry about in CBR is PCR.
is for connections that have variable traffic. The only parameter you need to worry about in UBR
is for connections that, while having variable traffic, require precise timing between traffic
source and destination. PCR, SCR and MBS must all be set for rtVBR.
is for connections that have variable traffic, do not require precise timing, but still require a
set bandwidth availability. PCR, SCR and MBS must all be set for nrtVBR.
Select the encapsulation protocol your ISP uses. The following section will vary depending on which
encapsulation protocol you select.
(1) Dynamic IP Address
Select this option if your ISP provides you an IP address automatically. Please enter the Dynamic IP
The following table describes the labels in this screen.
Select your encapsulation type from the dropdown list.
Select whether Bridge interface is Activated or Deactivated.
Select whether NAT is Enabled or Disabled.
Select whether this PVC will be the default route for Internet data.

Select the RIP type and direction from the dropdown lists.
Select the multicast protocol you wish to use from the dropdown list.
(2) Static IP Address
Select this option to set static IP information. You will need to enter in the encapsulation type (1483
Bridged IP LLC, 1483 Bridged IP VC-Mux, 1483 Routed IP LLC (IPoA), 1483 Routed IP VC-Mux),
IP address, subnet mask, and gateway address provided to you by your ISP. Each IP address entered in
