In NE Explorer >> DCC Management, the DCC Rate Configuration Tab shows none or few boards with DCC channels enable and obtained, but DCC Resource Allocation Tab shows that the DCC Channels are all taken.
The DCC Channels are configured 10 “Number of Allocation” for 3-Byte Rate and 10 for 9-Byte Rate. In DCC Resources Allocation Tab the user can see that channels are occupied but he/she can not check who is using the channels.
The Inspector Report shows that the DCC channels are all taken or almost all taken.
The NE could lose management.
The solution has to be done using Navegator.
Log in the NE and Run the following Navigator Commands:
:cm-get-dccpara; // This will show the number of DCC channels free and used
:cm-get-bdinfo; // This will show the board and port state information (port-enable/port-disable)
After you check which board has taken the DCC channels, you can disable each port with DCC channels obtained, (the ports that do not need to use the DCC Channels), to release the resources, then those channels can be obtained by the Line Boards that are interconnecting the NEs.
To release the resources, run the following command:
- bid: figure(_UC) => write the Board ID of the one you need to disable the ports
- port: figure(_UC) => write the port that you need to disable
- portstate: port-enable or port-disable => write port-disable
- dccrate: D1-D3 or D4-D12 or D1-D12; => write the DCC Rate you want to disable
After disabling the ports that were consuming the DCC channels resources, check if the boards you need to obtain the DCC channels, have obtained the resources.
Mostly times is cause by line boards that are not connecting equipment among each other obtaining the DCC Channels, even when those won’t be used. For example this happens with the SEP boards.
If transparent transmission is not being used, configure all the Allocation Resources for 3-Byte Rate.
Be sure of the ports of the boards that you need to obtain the resources are enable.
