QoS

 

 

 

 

 

ATM QoS

Select CBR (Continuous Bit Rate) to specify fixed (always-on)

 

 

bandwidth for voice or data traffic. Select UBR (Unspecified Bit Rate)

 

 

for applications that are non-time sensitive, such as e-mail. Select

 

 

rtVBR (real-time Variable Bit Rate) for applications with bursty

 

 

connections that require closely controlled delay and delay variation.

 

 

Select nrtVBR (non real-time Variable Bit Rate) for connections that

 

 

do not require closely controlled delay and delay variation.

 

 

 

 

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. Type the PCR in this field.

 

 

 

 

SCR

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

 

 

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

 

 

PCR. Note that system default is 0 cells/sec.

 

 

 

 

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

Select the connection type supported by your ISP. The next fields vary

 

 

depending on what connection type you use. See the following

 

 

sections for more details.

 

 

 

 

SAVE

Click this to save your changes.

 

 

 

 

DELETE

Click this to restore the PVC to default settings.
