Chapter 7 Internet Setup

Table 11 Interface Setup > Internet (continued)

LABEL	DESCRIPTION
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.
