China Telecom first in China to deploy Siemens MSPP technology

14 August 2003 Munich Lightwave--Siemens Information and Communications Networks has been commissioned by China Telecom to upgrade the carrier's optical network in Lanzhou in the province of Gansu. China Telecom is planning to deploy Siemens' new SURPASS hiT 7050 multi-service provisioning platform (MSPP) to support data services based on Ethernet in the metro domain alongside traditional SDH-based voice services. The carrier is the first in China to use Siemen's MSPP technology.

Siemens Information and Communications Networks
has been commissioned by China Telecom, to upgrade the carrier's optical network in Lanzhou, in the province of Gansu. China Telecom is planning to deploy Siemens' new SURPASS hiT 7050 multi-service provisioning platform (MSPP) to support data services based on Ethernet in the metro domain alongside traditional SDH-based voice services. The carrier is the first in China to use Siemen's MSPP technology.

The MSPP will allow China Telecom to upgrade its SDH-based network to a convergent network for voice, with a sharply increasing data component. The technology will bring new business opportunities for the carrier thanks to Ethernet services, which can be implemented alongside the SDH-based services with different classes of quality. For example, China Telecom will be able to offer Ethernet services with a guaranteed, flexibly adjustable bandwidth, according to Siemens.

The Surpass hiT 7050 platform is part of Siemens' newly developed Surpass hiT 70xx series. The family of products comprises end-to-end solutions for the metro core domain with Surpass hiT 7070, for the metro access domain extending to linking in large corporate locations with Surpass hiT 7050, and for customer locations with Surpass hiT 7030.

The SDH-based Surpass hiT 70xx series is designed to meet the growing demand for new Ethernet-based data services in metro networks. The compact solution capable of being expanded end-to-end will enable increased transmission capacity to be provided to handle increasing volumes of traffic and services. Optimizing for Ethernet services is achieved with the aid of technologies such as generic framing procedure (GFP), link capacity adjustment scheme (LCAS), resilient packet ring (RPR), and multi-protocol label switching (MPLS). Carriers can therefore dynamically match current bandwidth need to the requirements of the Ethernet services to make optimum use of available
network capacity.

China Telecommunications Corporation (CTC), headquartered in Beijing, is the largest fixed phone operator in the country. China Telecom provides fixed
domestic and international services (including voice, voice over IP, data, video and multimedia), Internet, virtual private networks, broadband, international settlements, as well as professional services including system integration, research and development, and import/export. CTC is the most experienced operator in China with an expansive infrastructure, a team of network professionals and strong research and development capabilities.
