PLANET ADN-4000 - Manual (Page 25)

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.
The following table describes the labels in this screen.
