The Clarets fell behind at Portman Road when David Norris struck for the Tractor Boys but Carlisle's injury-time equaliser gave Brian Laws' men a point.
Carlisle feels the result demonstrated the kind of mettle his side will need to keep producing over the next nine months.
He said: "We know the Championship. We know it's going to be a fight to the bitter end but we are ready for it and I think we showed that.
"A point is very welcome and I'm sure we'll look back at it fondly come the end of the season."
