Intellinet Network Solutions 524780 user manual Pcr, Cdvt, Scr, Mbs

	is included in the header of an ATM cell. The valid VCI
	range is 32 to 65535. Enter the VCI assigned by the ISP.
QoS	UBR (Unspecified Bit Rate) – Select UBR for applications
	that are non-time sensitive, such as e-mail.
	CBR (Constant Bit Rate) – This class is used for
	emulating circuit switching. The cell rate is constant with
	time. Select CBR to specify fixed (always on) bandwidth
	for voice or data traffic.
	nrtVBR (non-real time Variable Bit Rate) – This class
	allows users to send traffic at a rate that varies with time
	depending on the availability of user information.
	Statistical multiplexing is provided to make optimum use
	of network resources. Multimedia e-mail is an example of
	nrtVBR.
	rtVBR (real time Variable Bit Rate) – This class is similar
	to nrtVBR but is designed for applications that are
	sensitive to cell-delay variation. Examples for real-time
	VBR are voice with speech activity detection (SAD) and
	interactive compressed video.
PCR	Divide the DSL line rate (bps) by 424 (the size of an ATM
	cell) to find the PCR (Peak Cell Rate). This is the
	maximum rate at which the sender can send cells.
CDVT	PCR generally is coupled with the CDVT (Cell Delay
	Variation Tolerance), which indicates how much jitter is
	allowable.
SCR	SCR (Sustain Cell Rate) is the average rate over a long
	interval, in the order of the connection lifetime.
MBS	MBS (Maximum Burst Size) refers to the maximum
	number of cells that can be sent at the peak rate. Enter
	the MBS, which is less than 65535.
