Sangoma Technologies Now Shipping Latest A400 FXO/FXS Analog Telephony Support System

The A400 and REMORA system support up to 48 FXO/FXS ports

TORONTO, ONTARIO--(CCNMatthews - Nov. 30, 2006) - Sangoma Technologies Corporation (TSX VENTURE:STC)(, a leading provider of connectivity hardware and software products for VoIP, TDM voice, WANs and Internet infrastructure, is now shipping its A400 Series -- the high density version of the popular A200 series analog cards.

Identical in operation and configuration and using the same FXO and FXS modules, the A400 system supports twelve ports per main board and REMORA, as compared to four ports for the A200.

"As you need them, additional REMORA cards can be added to the base 12-port A400 card," says Sangoma Technologies president and CEO David Mandelstam. "A single PCI or PCI Express slot host connection can support up to 48 FXO/FXS ports with common synchronous clocking for all channels."

Like all the Sangoma AFT Series, the A400 and REMORA system has field upgradeable firmware to take advantage of enhancements as they become available. Optionally, the A400 supports Sangoma's echo cancellation and voice enhancement DSP daughterboard for carrier grade echo cancellation and voice enhancement.

Since launching the A200 earlier this year, we continue to see a huge demand for analog telephone connections in many countries around the world," adds Mandelstam. "VoIP telephony with all its promise still needs access to the existing PSTN network and many of those connections are analog FXO or FXS. To meet this requirement we are taking an industry lead by providing a price/performance solution that our competitors will now attempt to follow."

The A400 consists of an A400 REMORA daughterboard mounted on the AFT PCI /PCI Express. Each A400 REMORA card can support up to 12 FXO or FXS connections.

Up to three additional A400 REMORA daughterboards can be mounted in empty slot positions beside the A400 assembly, connected to the A400 by a backplane bus connector.

Each 12 port A400 REMORA card is connected by means of a standard 12-line color coded telephone cable terminating at the card in a robust DB25 connector, and ready for hard wiring into a punch block at for the PSTN connection.
