CDO's were ATCO's? Really...they weren't in my day. They were Clearance delivery officers and the guys I knew were ex ATCA's ...none of whom held an ATCO license.They certainly took requests on VHF but they were referred to the appropriate planner. The clearance came from the planner and was "read" to the aircraft by the CDO.
