Narrative:
From over pachuca VOR, vectors ILS runway 23L. Cleared to 11000 ft in VFR conditions, terrain visible. ATC cleared us to 10000 ft. At 10500 ft, received terrain warning as we passed over higher terrain which was visible. No terrain was showing on egpws and rate of descent was less than 1000 FPM. Subsequent vector to ILS runway 23L was inside OM. Ended up with visual approach. ATC kept us high and fast until 5-6 mi from runway. We were stable for final 1000 ft. Contributing factors. ATC speed request to hold 250 KTS until close to airport. Vector off planned arrival route and late descent for final approach from ATC.

Title: AN A320 FLC RPT REGARDING AN OFF COURSE DSCNT, APCH, VECTOR THAT CONTRIBUTED TO A LATER GPWS ALERT FROM TERRAIN CLRNC CONSIDERATIONS NE OF MMEX, FO.
Narrative: FROM OVER PACHUCA VOR, VECTORS ILS RWY 23L. CLRED TO 11000 FT IN VFR CONDITIONS, TERRAIN VISIBLE. ATC CLRED US TO 10000 FT. AT 10500 FT, RECEIVED TERRAIN WARNING AS WE PASSED OVER HIGHER TERRAIN WHICH WAS VISIBLE. NO TERRAIN WAS SHOWING ON EGPWS AND RATE OF DSCNT WAS LESS THAN 1000 FPM. SUBSEQUENT VECTOR TO ILS RWY 23L WAS INSIDE OM. ENDED UP WITH VISUAL APCH. ATC KEPT US HIGH AND FAST UNTIL 5-6 MI FROM RWY. WE WERE STABLE FOR FINAL 1000 FT. CONTRIBUTING FACTORS. ATC SPD REQUEST TO HOLD 250 KTS UNTIL CLOSE TO ARPT. VECTOR OFF PLANNED ARR RTE AND LATE DSCNT FOR FINAL APCH FROM ATC.
