9.3.6 Operations, Administration and Maintenance (OAM) Cell Servicing
The RCMP-200 is capable of terminating and monitoring F4 and F5 OAM flows.
Complete processing of Fault Management, Performance Management (PM) and
Continuity Check cells is provided. Activate/Deactivate and Loopback cells are
passed to the Microprocessor Cell Buffer or the Output Cell Interface for external
processing.
For the case of OAM processing, the following applies:
1. If the RCMP-200 is configured as a sink of PM cells, then the BIP-16, current
cell count, MSN, TUC, forward statistics and backward statistics are updated
independent of the outcome of cell policing.
2. If the RCMP-200 is configured as a source of PM cells, then the BIP-16,
current cell count, MSN and TUC are updated dependent of the outcome of
cell policing. That is, those fields are updated if and only if the cells are not
discarded by the RCMP-200.
The contents of the OAM Configuration field at SA[19:16]=0011 determine the
RCMP-200's behavior with respect to a particular connection:

Bit
Name
Action if a logic 1
7
CC_RDI
Setting this bit enables the sending of RDI cells at one
second intervals upon the declaration of a Continuity
Check alarm at a termination point (i.e. the CC_alarm bit
is set).
6
BACKRPT
Enables the generation of backward report cells. A
backward report cell is output for each forward
monitoring cell received at an OAM flow end-point if the
SRCPM bit is a logic 0.
5
Send_AIS
Sends an AIS cell once per second. The cells genrated
are encoded as End-to-End AIS cells.
4
Send_RDI
Sends an RDI cell once per second. The cells genrated
are encoded as End-to-End RDI cells.
