AGS+'s only could handle 16meg, the cpu in a AGS+ is the same as in a 7000 series, (motorola 68040) As of a year ago, I believe I heard that sprint still had AGS+'s in their backbone and were upgrading them to 7000 series equipment. -- Jason Jason Vanick ------------------------------------------ [email protected] Network Operations Manager V: 312-245-9015 MegsInet, Inc. 225 West Ohio St. Suite #400 Chicago, Il 60610
