This bit is set when the RX UTOPIA FIFO associated with an IMA Group overflows. This
bit is cleared by writing 0.
This bit is set when the counter for all cells associated with an IMA Group overflows. (Input
UTOPIA port). This bit is cleared by writing 0.
This bit is set when the counter for Idle Cells associated with an IMA Group overflows.
(Input UTOPIA port). This bit is cleared by writing 0.
This bit is set when the counter for Unassigned Cells associated with an IMA Group
overflows. (Input UTOPIA port). This bit is cleared by writing 0.
This bit is set when the counter for HEC Errored Cells associated with an IMA Group
overflows. (Input UTOPIA port). This bit is cleared by writing 0.
This bit is set when the RX TDM Link counter for bad ICP Cells associated with a link
overflows.
