Narrative:
Departing elp runway 26L, clearance was to 17000 ft 'deemer 1.' taking runway for takeoff, tower volume was low. We were clearing for takeoff, climb to 'one seven thousand,' which we read back with no argument or correction. On climb out, a light twin was pointed out at 7500 ft at our 11 O'clock position. We saw the traffic which was never a conflict. Then departure questioned if we were given 7000 ft as an altitude. We said no and were then cleared to 17000 ft. The terminology of 'one seven thousand' should be 'seventeen thousand' then the assignment of 'seven thousand' would not be confused on the clearance or the readback.

WE WERE CLRING FOR TKOF, CLB TO 'ONE SEVEN THOUSAND,' WHICH WE READ BACK WITH NO ARGUMENT OR CORRECTION. ON CLBOUT, A LIGHT TWIN WAS POINTED OUT AT 7500 FT AT OUR 11 O'CLOCK POS.
