A Get operation on this variable retrieves the LLSDCC Carrier GCC value. Setting this variable to NONE removes OSPF circuit and LLSDCC carrier info. It is a NO-op if the GCC is initially NONE. Setting the variable to any other value would create LLSDCC COMMS with that GCC value. unknonw is not a valid value for any set operation. An unknown value for a get may indicate problems retrieving the GCC from the facility. Avoid issuing set commands when an unknonw value is retrieved. This variable is available upon GET-EXACT only. No value is shown for GET-NEXT operations.
