The following table describes the labels in this screen:
| Field | Description |
| |
|
|
| ATM VC | |
| Virtual Circuit | VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) |
| |
| ID | define a virtual circuit. |
| |
| Status | Activated or Deactivated |
| |
| 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. |
| |
|
|
|
| |
|
|
| Select CBR (Continuous Bit Rate) to specify fixed |
|
|
|
| bandwidth for voice or data traffic. Select UBR (Unspecified Bit |
|
| ATM QoS |
| Rate) for applications that are |
|
|
| Select VBR (Variable Bit Rate) for bursty traffic and bandwidth |
| |
|
|
|
| |
|
|
| sharing with other applications. |
|
|
|
| VBR is not available on all models. |
|
| Cell Rate |
| Cell rate configuration often helps eliminate traffic congestion that |
|
|
| slows transmission of real time data such as audio and video |
| |
|
|
| connections. |
|
| Peak Cell Rate |
| 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 |
| |
| (PCR) |
|
| |
|
| the sender can send cells. Type the PCR here. |
| |
|
|
|
| |
| Sustain Cell |
| The Sustain Cell Rate (SCR) sets the average cell rate |
|
|
| that can be transmitted. Type the SCR, which must be less than |
| |
| Rate (SCR) |
|
| |
|
| the PCR. |
| |
|
|
|
| |
|
|
| ||
| Maximum Burst |
| 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 | ||
| Size (MBS) |
|
| |
|
| 65535. |
