aal1 Ces Partial Fill

A significant source of delay in a structured service is the amount of time it takes to collect enough data to fill a cell. This period of time can be reduced by sending cells that are only partially filled with data (idlePattern octets are added to the ATM payload beyond the partial fill level). This attribute defines the number of payload octets to fill with data. It is applicable to structured services only, and must be set to 47 for unstructured services. On a given AAL1 Function Processor, the maximum cell rate that can be sustained is dependent upon the combined bandwidths of the provisioned services, and (for structured services) the levels of partialFill. The smaller the partialFill level, the greater the cell rate and hence the fewer the services that can be sustained at that fill level.
