Committed Information Rate (CIR) describes how congestion
control is handled. Off indicates that no attempt
at congestion control is made. Constant indicates that
data is sent at a constant rate (set using usrfrCIRMinRate
and usrfrCIRMaxRate). Variable indicates that the BECN bit
of the Q.922 header is monitored. When the BECN bit
indicates that the Frame Relay switch is experiencing
congestion over this DLCI, the transmission rate will
be slowed to usrfrCircuitCIRMinRate. When the bit indicates
alleviation of congestion, the transmission rate will
be incrementally increased back to usrfrCircuitCIRMaxRate.
