Session Refresh 
The RFGW-1 generates an input pid conflict alarm (Alarms/Events section) if any ES 
or the PMT pid in an MPTS is the same as a pid already in use in the same MPTS. 
Recall that it is the users responsibility to ensure that the pids in an MPTS are 
unique.  To clear the pid conflict alarm it is necessary to not only resolve the input 
pid conflict at the source e.g. the DCM but also to refresh the associated sessions as 
seen...

Once the PID conflict is resolved at the headend device, then after refreshing the 
session, the PID conflict alarm will be cleared. The state in the Input Monitor page 
will also change to Active only after the session refresh is completed. Even if the 
input PID conflict is resolved, but the session refresh button is not clicked, then state 
in Input monitor page will remain as Input PID conflict

Fault Management of the RF Gateway 1 
The RF Gateway 1 supports automatic detection and user notification of changes in 
the system.  Changes may be classified as either Events or Alarms.  Alarms carry a 
state while events are important instances that occur in time and are reported.  For 
example, Link Lost and Link OK are two well-defined states and are associated with 
an alarm. Events Startup, Configuration Backup, and Second...
