limits the number of available buffers. Data that is delayed more than the
permitted maximum delay is discarded. If the SU supports applications that are
very sensitive to delay, the value of the Maximum Delay should be decreased.
Valid values range from 300 to 10000 (milliseconds).
The default value is 5000 (milliseconds).
Sets the limit on using the graceful degradation algorithm. In cases of over
demand, the performance of all SUs is degraded proportionally to their CIR
(IR=(100%-k%) x CIR). The graceful degradation algorithm is

in proportion to the demand in the cell. The higher the expected demand in a cell,
the higher the value of the Graceful Degradation Limit. Higher demand can be
expected in cases of significant over
subscription and/or in deployments whe
high number of subscribers are in locations without proper communication wi
