Traffic Descriptor
Type
Select one of the following traffic descriptor types and fill in the peak
cell rate (PCR), sustainable cell rate (SCR), maximum burst size
(MBS), and minimum cell rate (MCR) values as specified:
PCR CLP=0 (cells/sec) – Displays only if you selected a TD
combination that includes PCR CLP=0. If so, specify the PCR in
cells per second for high-priority traffic (that is, the CLP=0 cell
stream).
PCR CLP=0+1 (cells/sec) – Specify the PCR in cells per second for
the combined high- and low-priority traffic (that is, the CLP=0+1
aggregate cell stream).
SCR CLP=0 (cells/sec) – Displays only if you selected a TD
combination that includes SCR CLP=0. If so, specify the SCR in
cells per second for the combined high-priority traffic (that is, the
CLP=0 cell stream).
SCR CLP=0+1 (cells/sec) – Displays only if you selected a TD
combination that includes SCR CLP=0+1. If so, specify the SCR in
cells per second for the combined high- and low-priority traffic (that
is, the CLP=0+1 aggregate cell stream).
MBS CLP=0 (cells) – Displays only if you selected a TD
combination that includes MBS CLP=0. If so, specify the MBS (in
cells per second) for the combined high-priority traffic (that is, the
CLP=0 cell stream).
MBS CLP=0+1 (cells) – Displays only if you selected a TD
combination that includes MBS CLP=0+1. If so, specify the MBS (in
cells per second) for the combined high- and low-priority traffic (that
is, the CLP=0+1 cell stream).
MCR CLP=0 (cells/sec) – Displays only if you selected a TD
combination that includes MCR CLP=0. If so, specify the MCR (in
cells per second) for the combined high-priority traffic (that is, the
CLP=0 cell stream).
Although the MCR TD is only applicable to a CBX 500 with an FCP,
this attribute is offered as a selection on non-CBX endpoints. This is
because even though one or both endpoints may not be on a CBX
with FCP, the PVC might traverse a CBX 500 FCP trunk. In this
case, the provisioned attribute is used.
Note: On ATM CE endpoint(s), the PCR, SCR, and MCR cells/sec
values default to 118980 and cannot be changed.
