Routing Parameters
The routing parameter maxcost (specified using -mc option) need to be entered at the master endpoint
only. The values of the parameters entered at the slave end are ignored and during call set-up.
Frame Discard
For the parameter frame discard (specified using -frame option), you need to enter it at only the master
endpoint. This parameters has no significance at the slave end.
For the MGX 8850 2.0 release, if you try to enable frame discard at the slave end point you will not get
an error message. Nothing will happen, and frame discard will not take effect. In future releases, an error
message will be displayed if you try to enable frame discard at the slave end point.
Local-Only Parameters
The parameters CDVT, stats enable, cc enable (specified using -cdvt, -stat, -cc) are significant only at
the endpoint where you enter them. Therefore, they can be different at each end of the connection.

Ranges for PCR, SCR, and MCR for Each Line Type
Parameter
Range
PCR
Minimum value of 7 cell/sec.
Maximum depends on the physical line on which the interface is configured:
for OC12:between 7 and 1412832
for OC3:between 7 and 353208
for T3:between 7 and 96000(PLCP), 104268(ADM)
for E3:between 7 and 80000
for T1:between 7 and 3622
for E1:between 7 and 4528
Default : Taken from the SCT which was chosen for the virtual interface. The service
type is used as an index in choosing a value of PCR. The default value of PCR in the
SCT is defined as a percentage of the interface bandwidth.
SCR
Minimum value of 7 cells/sec.
Maximum is limited to the PCR.
Default: Taken from SCT as a percentage of PCR.
MCR
Same as SCR
