-rscr
addcon, cnfcon
Remote sustained cell rate (SCR). Specifies the SCR from a
remote endpoint to a local endpoint (3-5651328 cells per
second). SCR is the maximum cell rate that a connection can
sustain for long periods.
-lmbs
addcon, cnfcon
Specifies the MBS from a local endpoint to a remote
endpoint, in the range from 1-5000000 cells. MBS is the
maximum number of cells that can burst at the PCR and still
be compliant. In the operation of the GCRA (Generic Cell
Rate Algorithm), the MBS and SCR are closely related in
the generation of the burst tolerance. According to buffering
and the correct operation of the ATM chipset, the maximum
MBS is derived from the configured SCR, and the relative
values of SCR and PCR. The maximum obtained MBS will
reduce as the SCR becomes lower, and as the gap between
PCR and SCR gets larger.

PCR and SCR gets larger.
-lcdv
addcon, cnfcon
The local cell delay variation (CDV) parameter specifies the
maximum peak-to-peak CDV allowed from the local
endpoint to the remote endpoint. The range is 0 to 16777215
microseconds.
-rcdv
addcon, cnfcon
The remote CDV parameter specifies the maximum
peak-to-peak CDV from the remote endpoint to the local
endpoint. The range is 0 to 16777215 microseconds.
-lctd
addcon, cnfcon
The local CTD parameter specifies the maximum
cumulative CTD allowed from a local endpoint to a remote
endpoint. The range is 0 to 65535 milliseconds.
-rctd
addcon, cnfcon
The remote CTD parameter specifies the maximum
cumulative CTD allowed from the remote endpoint to the
local endpoint. The range is 0 to 65535 milliseconds.
-lmcr
addcon, cnfcon
Local minimum cell rate
OC3: 50 – 353207 cps
T3: 50 – 96000 (PLCP) cps or 104268 (ADM) cps
E3: 50 – 80000 cps
T1: 50-3622 cps
E1: 50-4528 cps
