| 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 the |
|
| sender can send cells. Type the PCR here. |
|
| This field is not available when you select UBR Without PCR. |
|

|
| Select VLAN MUX Mode to allow multiplexing of multiple protocols |
|
| over a single virtual circuit. You need to assign a VLAN ID and priority |
|
| level to traffic through each WAN connection. All WAN connections |
