y. If no data is received from
the Ethernet port during the last N seconds, the unit is allowed to transmit N
out any delay. For example, after a period of inactivity of
128 Kbps can transmit up to 128 Kbits x 0.5 =
64 Kbits without any delay.

A special algorithm for graceful degradation is incorporated into the AU, ensuring
that the degradation of performance for each individual Subscriber Unit is
proportional to its CIR.
The MIR/CIR algorithm uses buffers to control the flow of data. To balance the
performance over time, a special Burst Duration algorithm is employed to enable
higher transmission rates after a period of inactivit
