DESCRIPTION
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-RT (real-time Variable Bit Rate) type for
applications with bursty connections that require closely controlled delay and delay
variation. Select VBR-nRT (non real-time Variable Bit Rate) type for connections
that do not require closely controlled delay and delay variation.
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.
transmitted. Type the SCR, which must be less than the PCR. Note that system
default is 0 cells/sec.
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.
This feature is not applicable/available when you configure the ZyXEL Device to
use a static WAN IP address or in bridge mode.
Select Yes to set the ZyXEL Device to automatically detect the Internet connection
settings (such as the VCI/VPI numbers and the encapsulation method) from the ISP
and make the necessary configuration changes.
Select No to disable this feature. You must manually configure the ZyXEL Device
