Adax Provides Portable, Rapid Development Platforms for 3G

Adax, the industry leader in high performance wide area communications and signaling infrastructure, has completed its line-up of convergence technologies with the introduction of 10/100 BaseT Ethernet capabilities for its HDC multiple protocol controller.

Adding the Ethernet ports to the HDC provides direct connectivity to the Internet and other IP networks, enabling Adax to offer the complete solution for the convergence of IP with PSTN networks. The new boards serve as the signaling interface for convergence networks, softswitches and next generation network gateways, says Adax, whose products lie at the heart of telecoms systems from giants such as Alcatel, Ericsson, Lucent and Nortel.

“With the addition of Ethernet capabilities to our ATM Plus controllers last month, and now the HDC cards, this completes our convergence technology set,” said Robin Kent, Director of European operations at Adax. “Together with Adax’ SCTP/T software for high reliability IP signaling , our convergence hardware meets the signaling challenges of VoIP and multimedia wireless networks.”

Adax and SCTP SCTP is designed to transport PSTN signaling messages over IP networks. The Adax implementation of SCTP for telecoms, SCTP/T, has been designed for Convergence, Wireless and Intelligent Networks. Adax SCTP/T takes advantage of Adax’ high performance hardware, pushing critical parts of the protocol onto the on-board processors. Included in this is the heartbeat processor to establish and secure connections. This enables IP telephony networks to achieve the same levels of service, quality and reliability as those expected from a Public Switched Telephony Network (PSTN).

Adax HDC The HDC card is a high density, fully channelised, multiple protocol platform. It is dynamically configurable, providing up to 128 channels of SS7 MTP-2, SCTP, LAPB/D, Frame Relay, X.25 or HDLC in any combination per board. Four T1/E1 interfaces are provided through the QCX daughter card, and the HDC also has two 10/100 BaseT Ethernet ports available for connection to the Internet and other IP networks.

The HDC card provides a scalable solution for telco, industrial and other high-reliability applications (from PCs to enterprise servers), as the H.110 bus allows for the cross connection of multiple boards. Simultaneously, the high port density of the HDC card reduces slot space, resulting in a cost-effective solution. Four slots in a chassis result in 512 channels of processing. HDC has hot swap and hot plug capabilities and can be removed from service without interrupting the higher layers and applications in process.

Powerful on-board processors perform many transactions per second and provide efficient bandwidth management, freeing the host CPU and maximising its processing power for higher layers and applications. Adax claims the HDC achieves this performance without compromising the reliability that the telecommunications market requires.
