Routing Parameters
The routing paramet er 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

Table7-6 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 c hose n for the virt ual i nterf ac e. The se rvic e
type is used as an index in choosin g 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 th e P C R .
Default: Taken from SCT as a percentage of PCR.
MCR Same as SCR
