Provisioning 
This section provides information for provisioning the RF Gateway 1 for NGOD 
operation. 
Prerequisite configurations:  
 GbE input ports, including Video/Data IP address 
 QAM outputs 
 Channel Application Mode  
Channel Application Mode 
To Verify Channel Application Mode 
Navigate to the Qams page. 
1 Select the QAM channels and set the App Mode to NGOD. 
2 Set the TSID appropriately  
Result: App Mode is...

 Component Name  
 Local –  Region Name and Local NameComponent Name – The Name of the 
RFGW-1 
 QAM RF Port 1-12 names - These are used to advertise the QAM Ports to the 
ERM 
Names of the GigE ports 
 Bw Interval and Bw Threshold  The RFGW-1 checks every QAM to see if during 
a Bw Interval, there was a change in the bandwidth that is equal to or greater 
than the Threshold. This is used by the ERM to maintain Bandwidth. To disable 
the reporting, one...

g Connection Time out – This is how long the RFGW-1 waits for an R6 message  
before resetting the connection. 
h Session Time out – This is how long a session is kept alive by the RFGW-1 
without receiving a R6 session refresh (Ping) from the ERM 
i Announce Time out – This is how long the RFGW-1 waits before resending 
an Announce Message.  
 
 
  

 
 
 Status Monitoring 
 
78-4025112-01 Rev H0 241 
 
Status Monitoring 
Status monitoring of the R6/D6 messages between the ERM and the RFGW-1 is 
shown on the Monitor tab of the RFGW. 
The types of messages and the protocol are shown in the tab. The IP Address in the 
first column is the address of the ERM and the number with a dash represents the 
time the connection has been on. For e.g. in the figure below 10.90.146.108 ERM has 
been in the connected state for the last 4555 minutes.

Troubleshooting 
 RFGW-1 QAMs are not recognized by the ERM. 
 Check the “State” on the D6/R6 comm. Config page. If it is in StartUp/Establish 
connection state for more than a few minutes,  the RFGW-1 is unable to 
communicate with the ERM. Check the TCP connections between the RFGW-1 
and the ERM. 
 Check if the Streaming Zone (RegionName.LocalName) is correct. Ensure that 
the ERM is configured in the same Streaming Zone as the...
