BEIJING -- Yangquan Coal Industry (Group) Co., Ltd, a large state-owned coal enterprise in China, has selected Nokia Siemens Networks as its major supplier to migrate its traditional fixed network to a Next Generation Network (NGN) Solution that will provide the company with new, converged voice and data applications and multi-media services. Nokia Siemens Networks' solution will allow Yangquan to introduce these new communication services quickly and cost effectively.

The decision to upgrade was prompted by the inefficiency of Yangquan Coal Industry Group's current company-wide network, which required support for two different PSTN switches. The NGN solution from Nokia Siemens Networks will optimize the company's existing fixed network by replacing the legacy switches, provide an increased number of flexible access nodes, and implement an Integrated Access Device (IAD), a customer-hosted device that acts as a media gateway for accessing an IP network that will enable Yangquan Coal Industry Group to efficiently scale up to the number of users.

Says Zheng Haishan, Chairman of Telecommunications Technology Company Of Yangquan Coal Industry Group, "When we decided to upgrade our existing network and were evaluating between vendors, what struck us about Nokia Siemens Networks was their high performance products, rich, technical expertise, good service support and customer-focused attitude. We are keen to work with them to deliver new age flexible voice and multimedia services to our end users."
