DESCRIPTION

 

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.

 

 

 

 

Sustainable

The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that

 

Cell Rate

can be transmitted. Type the SCR, which must be less than the PCR.

 

 

Note that system default is 0 cells/sec.

 

 

This field is available only when you select Non Realtime VBR or

 

 

Realtime VBR.

 

 

 

 

Maximum

Maximum Burst Size (MBS) refers to the maximum number of cells

 

Burst Size

that can be sent at the peak rate. Type the MBS, which is less than

 

 

65535.

 

 

This field is available only when you select Non Realtime VBR or

 

 

Realtime VBR.

 

 

 

 

Select

Select Default Mode to allow only one WAN service over a single

 

Connection Mode

virtual circuit.

 

 

Select MSC Mode to allow multiple WAN services over a single virtual

 

 

circuit. Each WAN connection has its own MAC address.

 

 

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

 

 

share one MAC address.

 

 

This field is not available if you select PPPoA or IPoA as the DSL link

 

 

type. The P-2812HNU-51c uses Default Mode automatically for

 

 

PPPoA or IPoA.

 

 

 

 

Enable Quality Of

Select this option to activate QoS (Quality of Service) on this interface

 

Service

to group and prioritize traffic. Traffic is grouped according to the VLAN

 

 

group.

 

 

The QoS setting applies to all WAN connections over the same PVC.

 

 

This field is not available when you select CBR or Realtime VBR.
