We begin shipping the 56Kbps modems for the traditional MAX family immediately. We currently have over 550,000 ports of the MAX and MAX TNT 56Kbps installed in ISPs worldwide. The GRF is being used, or is in the testing phase, with 20 of the 35 U.S. backbone providers. New customer wins for the GRF 400 this quarter include Essential Communications and Connect One. Overall, the GRF product is right on track with our internal plan and we are very pleased with the progress it has made this quarter.
Frame relay appears be strengthening.
We continue to build our market position in frame relay this quarter with the new customers, including Frontier, Teleport Communication Group, and MetroNet Communications. We continue to be pleased with the success and acceptance of the CBX-500. On a going-forward basis, we will be reporting revenue breakouts on a business units basis, rather than on a products basis. The effort to increase the presence of Cascade in international markets paid off this quarter with a new customers in German, Switzerland, and France. International demand for Ascend products was tempered this quarter by production transition issues.
