PTT - Post, Telephone and Telegraph administration has selected ADC's Cellworx Service Transport Node (STN (SuperTwisted Nematic) A passive matrix LCD technology that provides better contrast than twisted nematic (TN) by twisting the molecules from 180 to 270 degrees. See DSTN. ) to provide voice, frame relay A high-speed packet switching protocol used in wide area networks (WANs). Providing a granular service of up to DS3 speed (45 Mbps), it has become popular for LAN to LAN connections across remote distances, and services are offered by most major carriers. , and ATM transport services The collective functions of layers 1 through 4 of the OSI model. for the PTT's access network. The initial purchase, 13 nodes for three STM-4c rings, represents the first international ATM virtual path ring deployment for any PTT. The total solution, which also includes ADC's ATM Access Concentrators, will be supplied and integrated through ADC's partner Gaohong Telecom Co. Ltd.
In selecting the Cellworx ATM virtual path ring solution, the Beijing PTT chose a more cost-effective architecture to SDH (Synchronous Digital Hierarchy) The European counterpart to SONET. See SONET.
SDH - Synchronous Digital Hierarchy . The Cellworx STN system can save carriers up to 50 percent of first-cost capital savings. Through customization of the STN's network management interface, Gaohong has jointly developed a variant of the STN called the AP-900 to address the specific needs of the Chinese market.
"China's diverse telecom infrastructure is one of the largest in the world," said Karl Rookstool, vice president of marketing for ADC's Broadband Access See broadband and wireless broadband. and Transport Group. "The Beijing PTT's selection of Cellworx ratifies the ATM VP ring solution as an economical, international, carrier-class method of broadband service delivery."
"We are very glad that the AP-900 has become the first market-available, mature ATM virtual path ring product in China," said Ms. Zhao Xirong, chief executive officer of Gaohong Telecom. "Through our joint endeavor with ADC, we have distinguished ourselves among competitors, and we believe that this success will lead us to series of achievements in the future."
The Cellworx STN is an ATM virtual path ring transport element that offers carriers bandwidth-efficient, multiservice delivery to support current and future broadband demand. Providing bandwidth-on-demand, Cellworx STN frees up stranded bandwidth to support more subscribers, without significant infrastructure investments. Cellworx maintains the survivability sur·viv·a·ble
