INVERSE MULTIPLEXING OVER ATM
Unusable_link
Force Links to an unusable state and provide
the cause.
For Rx Links, if the cause is inhibited, the links
are taken through the blocking state to preserve
data sent prior the link being inhibited. If the
cause is a fault or a failure condition, the link is
taken directly to the UNUSABLE state. At this
point, data would have already begun to be
discarded due to the defects detected on the
link.
For Tx Links, data will stop being accepted on
the Unusable links and IMA frames will be
generated consisting of filler cells.
Update_test_ptn
Update_TX_TRL
Update the TX test pattern info to be sent in the
outgoing ICP cells.
This command is used to activate, deactivate,
or change the test pattern that is being sent out
on the Group.
Update the transmit TRL.
When a TRL is changed, three steps are
performed: (1) the TRL sent in the ICP cell is
changed;(2) the TRL used for calculating the
IDCC is changed, and (3) the TRL used in the
stuffing algorithm is changed.
Read_event
Read and clear the latched event status, and
read the link/group status of the specified group
and all its links.
The result read from the internal context
memory is stored in Cmd_data00 through
Cmd_data1F. Refer to RIPP Command Data
Registers for further details.
