Internet (VC Configuration)
Go to
Interface Setup > Internet
to add or delete ADSL VC configuration. These information are
provided by your ISP.
ATM VC
ATM settings are used to connect to your ISP. Your ISP provides VPI, VCI settings to you. In this
Device, you can totally setup 8 VCs on different encapsulations, if you apply 8 different virtual circuits
from your ISP. You need to activate the VC to take effect. For PVCs management, you can use ATM
QoS to setup each PVC traffic line's priority.
• VCI:
The valid range for the VCI is 1 to 65535. Enter the VCI assigned to you. This field may already
be configured.
• VPI:
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you. This field may already be
configured.
• Virtual Circuit:
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a virtual circuit.
• PVC Summary:
• ATM QoS:
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.
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
