There are 55xx talkgroup ID's assigned to specific uses at the console. When those are patched to the standard talkgroups, the dynamic 65xxx ID's are created. What we do not know are the 55xx assigned talkgroups. I would not label the 65xxx as anything other than "dynamic patch". The 55xx numbers are considered console assignments as they don't show up directly in any field radios that I know about.
