Description 

QAM channel restarted, 
packet dropped 

CRITICAL 

The QAM module does not manage to synch properly to the 
signal received from the internal IP-output card. This causes 
the QAM module to restart the channel.  
 
The reason could be either: 
1)  
No services are configured, such that only NULL packets are 
sent to the QAM, hence the QAM does not find a PCR.  
 
2) 
The PCR that it receives is too jittery – which may happen 
when the services being sent to the modulator has been 
descrambled from an IPIN MPTS. If this is the case try to use 
the Alt CAM descrambling  mode for the services being 
descrambled
