Kallastra, a PCI/cPCI board manufacturer for VoIP, Host Media Processing and Multi-Chassis markets, today announced that C3, a leading supplier of technology platforms for voice processing applications, has selected Kallastra's KeyTrunk300 card for their Multi-Chassis interconnect solution.

The KeyTrunk300 Series offers a very cost-effective, high-density board solution for interconnection of Computer Telephony (CT) chassis. By interconnecting multiple chassis together, single chassis limitations in terms of I/O slots, TDM timeslots, and system capacity can be overcome. In particular, by using Ethernet-based technology, the KeyTrunk300 Series offers a completely scalable system where any number of chassis can be interconnected together.

"We are very pleased with the KeyTrunk300 Series card as it has allowed us to rapidly switch over to a new multi-chassis solution with minimum software and integration effort" explains Wayne Starsmore, Technical Director at C3.

"Kallastra's boards offers us a completely scalable solution, as well as a smooth migration to IP-based networks".

"Kallastra has been working very closely with C3's engineering team, and has been able to deliver and support the products with the features that C3 needs to grow and expand their systems" said Frederic Dickey, Director of Sales and Marketing at Kallastra. "We have been happy to work with C3 and demonstrate the robustness of the Kallastra product, and deliver the features that allow C3 to have a competitive edge in today's market".

The KeyTrunk300 Series provides a scalable solution for open CT systems, and is capable of processing between 128 and 2,016 channels per board. By using a specialised mode where multiple TDM streams are dynamically mapped into single packets, the KeyTrunk300 Series offers an extremely low-latency connection between computer chassis, typically 1 to 2 ms. The KeyTrunk300 Series supports standard TDM bus interfaces as well dual Ethernet ports.
