rate is not guaranteed because it is dependent on the line speed.

SCR: Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can

be sent at the peak rate, and a parameter for burst-type traffic. SCR may not be greater than

the PCR; the system default is 0 cells/sec.

MBS: Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the

PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again.

At this time, more cells (up to the MBS) can be sent at the PCR again.

CBR is for connections that support constant rates of data transfer. The only parameter you

need to worry about in CBR is PCR.

UBR is for connections that have variable traffic. The only parameter you need to worry about

in UBR is PCR.

rtVBR is for connections that, while having variable traffic, require precise timing between

traffic source and destination. PCR, SCR and MBS must all be set for rtVBR.

nrtVBR is for connections that have variable traffic, do not require precise timing, but still

require a set bandwidth availability. PCR, SCR and MBS must all be set for nrtVBR.

6.1.2 Encapsulation

Select the encapsulation protocol your ISP uses. The following section will vary depending on

which encapsulation protocol you select.

(1) Dynamic IP Address

Select this option if your ISP provides you an IP address automatically. Please enter the

Dynamic IP information accordingly.
