Released  
13.7 IMA Performance Parameters and Failure Alarms Support  
A number of IMA performance parameters and failure alarms are defined in the IMA spec  
(section 12.2.2) as a standardized interface to IMA unit management functions. The following  
text summarizes the support provided by S/UNI-IMA-4 to implement those functions.

S/UNI-IMA-4 provides read access to the TX LSM in RIPP  
link context records. Note after link start-up, it is up to PM  
to put the LSM into UNUSABLE state.  
R-131  
RX-UUS-IMA  
S/UNI-IMA-4 provides read access to the RX LSM in link  
context records. Note after link start-up, it is up to PM to  
put the LSM into UNUSABLE state.

S/UNI-IMA-4 may generate an interrupt once FE TX LSM is  
in UNUSABLE state, PM may then read the FE LSM state  
in the RIPP context memory to determine the case.  
O-22  
RX-FC-FE  
S/UNI-IMA-4 may generate an interrupt once FE RX LSM  
is in UNUSABLE state, or an RDI-IMA indication is sent by  
FE.
