atmIfVpcTmAbrCutoffDecreaseFactor 1.3.6.1.4.1.562.2.4.1.114.4.9.2.110.1.17

This attribute is applicable and is displayed only for connections for which the operational Tm abrConnectionType is displayed as sourceDest or virtualSourceDest. This attribute indicates the Cutoff Decrease Factor (CDF) parameter for this connection. When the value of this attribute is non-zero, CDF is computed as the inverse of the value. For example, if the value is 32, the value of CDF is 1/32. When the value of this attribute is 0, CDF is also zero. CDF controls the decrease in the Allowed Cell Rate (ACR) associated with the forwardRmCellLimit attribute, the limit of the number of forward Resource Management (RM) cells which may be sent in the absence of received backward RM cells. When this limit is crossed, the ACR value would be decreased by the amount (CDF*ACR). The ACR is not allowed to fall below the Minimum Cell Rate (MCR), in which case the ACR is set to MCR. For nailed-up connections, this attribute is determined by the provisioned value of the cutoffDecreaseFactor attribute. For signalled connections, it is indicated in the ABR Additional Parameters Information Element.
