This read-write integer sets the Minimum Cell Rate (MCR) guaranteed for a standard ABR connection, explicitly noted to include bandwidth consumed by both data cells and in-rate RM cells combined, and bounded by the logical port's actual speed. Admins configure this as the floor rate the ABR connection is entitled to regardless of congestion feedback, similar in spirit to the general ausmConnMCR but specific to the standard ABR TM4.0 parameter set. For example, when calculating whether a port has spare capacity for additional connections, an admin must remember that this MCR figure already accounts for RM cell overhead, not just user data.
