DESCRIPTION

ATM QoS Type

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 VBR-nRT(Variable Bit Rate-non Real Time) or VBR-RT

 

(Variable Bit Rate-Real Time) for bursty traffic and bandwidth

 

sharing with other applications.

 

 

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.

 

 

Sustain Cell Rate

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.

 

 

Maximum Burst Size

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.

 

 

MTU

 

 

 

MTU

The Maximum Transmission Unit (MTU) defines the size of the

 

largest packet allowed on an interface or connection. Enter the

 

MTU in this field.

 

For ENET ENCAP, the MTU value is 1500.

 

For PPPoE, the MTU value is 1492.

 

For PPPoA and RFC, the MTU is 65535.
