xcel's Integrated SS7 Enables Suntek to Gain China Network Access Certification Protocol Variant Approved by China MPT for Network Connection HYANNIS, Mass.--(BUSINESS WIRE)--May 7, 1998-- Excel Switching Corporation (Nasdaq:XLSW - news) announced today that, utilizing Excel's SS7 software, the Suntek Group of Guangzhou, China has successfully passed MTP1-3 and China TUP signaling testing by the Chinese Ministry of Posts and Telecommunications, now known as the Ministry of Information Industry.
