Sangoma Introduces New High-Performance Data Cards for Mission-Critical Communications

Cards improve performance of synchronous serial applications

TORONTO, ONTARIO--(Marketwire - Feb. 27, 2008) - Sangoma® Technologies Corporation (TSX VENTURE:STC), the premium provider of PC-based telephony hardware and software products for proprietary and open source based networking and telephony solutions, announced today new high speed two-port and four-port synchronous serial data cards that reduce system load. The new A142 and A144 data cards replace the legacy S5141 and S5142 cards. This new design improves system efficiency, supports multi-megabit speeds on all ports and is based on the same advanced engineering as the award-winning AFT product line.

The updated cards are a part of Sangoma's networking product line, and ideal for communicating mission critical radar control and surveillance data, essential to modern air and sea communications. Improvements include field upgradeable firmware, a choice of PCI or PCI Express interface, 2U form factor and two or four high speed RS232 or V.35/X.21/EIA530 ports.

Sangoma has also recently released the A56 data card, which replaced the Sangoma S5145 card. The Sangoma A56 card is the alternative to using an external router when using a 56kbps Digital Data System Line connection, and is ideal for rugged, extreme or remote environments.

"Sangoma has built its reputation on being the most reliable, and it's a moniker we are very protective of," says Kathleen Reed, Sangoma's Marketing Director. "As the premiere provider of voice and data cards, it's critical that our cards just work. It's the main reason we have become the cards of choice for mission-critical applications."
