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, as
measured 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. Type
the MBS, which is less than 65535.
