 rt-VBR (real-time Variable Bit Rate): When rt-VBR is selected, the SCR

and MBS fields are enabled.

PCR: Peak Cell Rate, measured in cells/sec., is the cell rate which the source may

never exceed.

CDVT: Cell Delay Variation Tolerance, is a QoS parameter in ATM network for

managing traffic that is specified when a connection is set up. In CBR

transmissions, CDVT determines the level of jitter that is tolerable for the data

samples taken by the PCR.

SCR: Sustained Cell Rate, measured in cells/sec., is the average cell rate over the

duration of the connection.

MBS: Maximum Burst Size, a traffic parameter that specifies the maximum

number of cells that can be transmitted at the peak cell rate.

Apply Changes: Click to set new PVC QoS mode for the selected PVC. New

parameters will take effect after save into flash memory and reboot the system.

Undo: Discard your settings.
