Chapter 7 Internet Setup Table 11 Interface Setup > Internet (continued) LABEL DESCRIPTION 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.

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.
