ATM VC
Virtual Circuit: VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a
virtual circuit.
VPI:The valid range for the VPI is 0 to 255. Enter the VPI assigned to you. This field
may already be configured.
VCI: The valid range for the VCI is 32 to 65535. Enter the VCI assigned to you. This
field may already be configured.
ATM QoS: Select CBR to specify fixed (always-on) bandwidth for voice or data traffic.
Select UBR for applications that are non-time sensitive, such as e-mail. Select VBR for
burst traffic and bandwidth sharing with other applications.
PCR: Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak
Cell Rate (PCR). This is the maximum rate at which the sender can send cells.
SCR: The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can be
transmitted.
MBS: Maximum Burst Size (MBS) refers to the maximum number of cells that can be
sent at the peak rate. Type the MBS, which is less than 65535
Encapsulation:
ISP: Select the encapsulation type your ISP uses from the Encapsulation list. Dynamic
IP Address, Static IP Address, PPPoE/PPPoA, and Bridge Mode. Choices vary
depending on your connection type requirement from ISP.
If you select Routing in the Mode field, select PPPoA, 1483 Bridged IP, 1483 Router IP
or PPPoE.
