Description
Rate Decrease Factor
Used in the ACR calculation for the relative
rate marking mechanism.
See
Maximum number of cells (user and BRM)
between two in-rate FRM cells.
Configured globally in firmware (via mailbox)
After Trm the next FRM cell is generated if at
least two in-rate cells (user or BRM) have
been sent.
Range x Granularity: (0..15) x 10 ms
Configured in global register
ACR Decrease Time Factor
Time-out of a connection; if no user cells are
received for this time the connection is
considered inactive and has to restart with
ICR.
Controls the bandwidth allocation between
RM cells and user cells. Minimum 2 user cells
must be transmitted between two consecutive
FRM cells.
Tagged cell rate
Limits insertion rate of out-of-rate FRM cells.
Parameter unused,
TCR triggered by Trm time-out (ToT)
Cutoff Decrease Factor
Controls the decrease in ACR as a result of
CRM (see below)
