China Broadcast and CATV Deploys RAD's IPmux Provision Value-Added Services over Gigabit Ethernet Network

Their first customer in Jiangsu province was the State Tax Bureau, which wanted to use Jiangyin CATV's GbE backbone to transport data and voice between its various offices throughout the Jiangyin region. Jiangyin CATV chose to implement a private, high speed virtual leased line services network based on RAD's IPmux-4 TDM over IP (TDMoIP) gateway. TDMoIP technology enables voice, video and data traffic to be carried transparently over high bandwidth packet networks. "RAD's TDMoIP solution, based on the IPmux-4, gave us a cost-effective and seamless path to enter the value-added service market quickly," states Mr. Peng Sun, General Manager at Jiangyin CATV. "TDMoIP is ideal for supporting the range of services -- from n x 64kbps up to E1 and H.320 videoconferencing -- that we want to offer business and government customers."

The IPmux-4 is deployed at each site to deliver leased line and legacy services over the GbE backbone network, which consists of Nortel Accelar GbE switches. Currently, 20 IPmux-4 units are installed and operating at 14 different offices.

"We are very pleased with RAD's solution and have plans to install an additional 40 IPmux units. The IPmux is easy to install and configure, which enabled us to perform the initial installation and commissioning in only one week," adds Sun. The IPmux received high marks from the professional testing lab in China, which operates under the umbrella of the China Science Academy.

RAD's solution has allowed Jiangyin CATV to launch a range of value-added services quickly and with minimal investment by leveraging its existing GbE infrastructure. This has accelerated its entry into the market as a competitive carrier. "The low entry cost of the IPmux, along with the potential revenue from these new services, enables us to offer E1 leased lines at a price comparable to that charged by the incumbent operator for a 64 kbps circuit," explains Sun.
