Do you mean "Arca N.A. Telecom Index"?
The Arca N.A. Telecom RIC is .XTC or 0#.XTC for chain.
I suspect that you are upgrading from an old version that use 4-part subject name convention.
.NaE means "not from the exchange". It is used in the old 4-part subject name convention where request subject must consist of "<Server>.<Service>.<Item>.<Exchange>".
RFA 8.0 nolonger use 4-part subject name and doesn't need .NaE extension with consolidated RICs anymore.
