AAL This field displays the ATM Adaptation Layer (AAL).
Class This field displays the type of ATM traffic class: cbr (constant bit rate), rt-vbr (real-time variable bit
rate), nrt-vbr (non real-time variable bit rate), ubr (unspecified bit rate) or abr (available bit rate).
PCR This is the Peak Cell Rate (PCR), the maximum rate at which the sender can send cells.
CDVT This field displays the accepted tolerance of the difference between a cell’s transfer delay and the
expected transfer delay.
SCR/MCR The Sustained Cell Rate (SCR) sets the average cell rate (long-term) that can be transmitted. SCR
applies with the rt-vbr and nrt-vbr traffic classes.
Minimum Cell Rate (MCR) is the minimum rate at which the sender can send cells. MCR applies
with the abr traffic class.
BT/NRM Burst Tolerance (BT) is the maximum number of cells that the port is guaranteed to handle without
any discards. BT applies with the rt-vbr and nrt-vbr traffic classes.
The Number of Resource Management (NRM) cells is the maximum number of cells a source may
send for each forward Resource Management cell. NRM applies with the abr traffic class.
