High Density Protocol Solution from Adax offers enough Streaming Power to "Build a Signaling Node in a PC"

Third generation Intelligent Network (IN) applications such as Signaling Transfer Points, Base Station Controllers and Mobile Switching centers that require high density channelised signaling can now execute up to 128 independent protocol streams via a single PCI or cPCI board from Adax. The new Adax High Density Channelised (HDC) platform delivers enough channelised control across multiple protocols to support IN developments in the emerging 3G wireless, wireline, mobile IP and advanced datacom markets.

The HDC-cPCI platform has the ability to execute its 128 protocol streams with up to 32 channels of the SS7 MTP-2 protocol or 128 channels of a wide variety of standard protocols including LAPB/LAPD, Frame Relay, LAPV5 and X.25. This takes place on time division multiplexed (TDM) DS0 channels and 4 T1/E1 trunks on a single card.

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 as many as 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.

The T1 or E1 connections are provided to the HDC board by the Adax ANC-QCX Network Controller card, which also provides the CSU/DSU functionality. The HDC board provides access to all the DS0s in a trunk line, and accepts incoming T1/E1 lines via the QCX daughter card. The QCX then breaks the data into 32 DS0s (E1) which can then be flexibly allocated.

“The HDC-cPCI card is designed for the next generation IN systems and sets a new standard for communications process performance in wireless, telco, mobile IP and advanced datacom applications – it will even allow a signaling node to be built in a PC," commented Robin Kent, Director of European Operations at Adax. "Adax designed the card in anticipation of the protocol tasks that have not yet been defined, but will surely appear in this frantically evolving communications sector.”

The HDC is available now for the Sun Solaris 32 and 64 bit operating systems and will shortly be available for most of the main UNIX operating systems including: HP-UX, AIX, Unixware and Linux.
