idleerr
Description
29
Idle Cell Received during IMA status. This status
is maintained by the RDAT to report occurrences
of idle cells on IMA links to PM via the RIPP. This
bit will be set when an idle cell is detected on an
IMA link, and will be cleared when the RDAT
message clear command is issued with the
idleerr_clear bit set (indicating that the RIPP has
acknowledged the problem).
28: 26
25:23 stuff_cnt
Reserved
Current link stuff count. This indicates the
occurrence of the next stuff event. When an ICP
cell is received, this count is set to the value in the
link stuff indication in that cell. In the event of an
errored, invalid, or missing ICP cell, the count will
be automatically decremented (unless the count is
000 or 111). Note that an invalid stuff sequence
will be interpreted as an invalid ICP cell.
111 No imminent stuff event.
110-101
Reserved.
100 Stuff event in 4 ICP cell locations.
011 Stuff event in 3 ICP cell locations.
010 Stuff event in 2 ICP cell locations.
001 Stuff event in 1 ICP cell locations.
000 The next cell received on this link is a stuff
event.
