TX_LASR_ACT
32-bit vector in which each bit corresponds to
one TX physical link in the TIMA Transmit LID
to Physical Link Mapping Table.
“0”: the link is not currently involved in a LASR
procedure.
“1”: the link is currently involved in an active
LASR procedure.

RX_FE_INFO_VALID
This indicates whether the context data fields
captured from incoming ICP cells) or not.
‘0’: Invalid.
‘1’: Valid.
This bit is set internally by RIPP during group
start-up upon capturing the first valid incoming
ICP cells.
This field will remain at its current value during
a group-restart.

RX_M
Receive IMA frame length (M). This parameter
is captured from incoming ICP cells during
group-start-up negotiation process, and later
used by RDAT in the receive IMA operation.
“00”: M = 32
“01”: M = 64
“10”: M = 128
“11”: M = 256

FE_SYM_MODE
FE_IMA_OAM_LABEL
RX_SCCI
Group symmetrical mode as indicated by the
FE in the latest ICP cell analyzed
IMA OAM label value as indicated by the FE in
the latest ICP cell analyzed
Current RX SCCI value for the group. This
value is captured from the incoming ICP cells
and used to determine whether the ICP cell
should be processed.
This field will remain at its current value during
a group-restart.
7:0
RX_IMA_ID
Stores the RX_IMA_ID. The value may be
copied from the RX_IMA_ID_CFG field in the
configuration memory if the
RX_IMA_ID_CFG_EN bit is set, otherwise it is
captured from the first incoming ICP cell after
the group is added or restarted.
