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.
