Table 7-8 SCT Bandwidth Parameter Descriptions
Parameter Description
SERV-TYPE The service type (for example, CBR, VBR, ABR) to which the parameters in this
table apply (for example, COSB_NUM, CAC_TYPE, UPC_ENB).
PCR Specifies the maximum PCR for a connection using this service type. The value is
a percentage of the maximum cell rate for the logical interface. 1000000 is equal
to 100%.
The range and units are 0 to 1000000.
SCR Specifies the SCR
1
for a connection using this service type. The value is a
percentage of the maximum cell rate for the logical interface. 1000000 is equal to
100%.
The range and units are from 0 to 1000000.
1. SCR = sustained cell rate
MCR Specifies the MCR
2
for a connection using this service type. The value is a
percentage of the maximum cell rate for the logical interface. 1000000 is equal to
100%.
The range and units are from 0 to 1000000.
2. MCR = minimum cell rate
MBS Specifies the maximum number of cells that can arrive at a rate equal to the PCR.
The MBS
3
is used for policing.
The range and units are from 1 to 5000000.
3. MBS = maximum burst size
CDVT Specifies the CDVT
4
for the first leaky bucket.
4. CDVT = cell delay variation tolerance
ICR Specifies the ICR
5
for a transmission on a connection that has been idle for a
configured period of time. The value is a percentage of the PCR for the logical
interface. 1000000 is equal to 100%.
Note ABR service type connections are used only.
The range and units are from 0 to 1000000.
5. ICR = initial cell rate
MFS Specifies the AAL5 MFS
6
in cells.
6. MFS = maximum frame size
