At or Below crossing restrictions on an RNAV departure
Was assigned an RNAV departure with cross at or below fix ABC at 7000 ft and then at or below fix XYZ at 9000. We than checked in with departure control and we were told to climb and maintain FL270.
I was of the understanding that you still must comply with the crossing restrictions, ABC at 7000 and XYZ at 9000, before we can climb and maintain FL270?
If this is true than what phraseology must ATC use to disregard the at or below crossing restictions?
Thanks for help with this,
RS
