Licenses about Control Matrix

I have two Q-Host in different Systems.

I checked the licenses in the different Hosts.

One Host has the license called 'Generic Singage', and another one doesn't have it.

At first, I didn't know the function or the privilege about this license, till someday when I did some test with TAPC protocol, I executed the command 'x l n.... ' and 'x s n ....', but the following things exceed my expectation:

I didn't receive any  echo message from a Q-Host, but I received the echo messages from another Host, such as:
"S ID PAGE_NEW_REQ,
   S ID PAGE_ACTIVE
   ...
   S ID PAGE_TIMEOUT...
...
...
And I was puzzled... I checked and checked....

Finally..I found the different config about the two Host, One has the 'Generic Singage',and another one doesn't.
I thought that I don't get the echo message may be relate to the 'Generic Singage' License.
Then I did a test to verify my conclusion:

I deleted the License 'Generic Singage' from the Host which echo messages, I executed the TAPC command again, and It can not echo me the message before. I added back to the Host, It can echo me the messages.

Through those test.... I get the conclusion..  'Generic Singage' License is relevant to the echo message..

In my system, I have to use the echo message. If what I said above is correct.. I have to got another 'Generic Singage' License.

Does the License Free Or Pay?

How Can I Get It?

Any Help is Appreciated!
   
Thanks, and Good Day!
