Sangoma Technologies Announces a New Standard in
Price/Performance for T1/E1/J1

TORONTO, ONTARIO--(CCNMatthews - May 3, 2004) -  

- Advanced Flexible Telecommunication cards redefine cost 
efficiency ratios  for WAN connectivity 

With over 20 years of engineering and technical expertise, 
Sangoma Technologies Corporation (TSXV: STC) (www.sangoma.com), a 
leading provider of connectivity hardware and software products 
for WANs and Internet infrastructure, has introduced its new 
Advanced Flexible Telecommunications (AFT) series of cards. 

The first of these cards to be released is the 2U form factor 
A101 (120mm x 55 mm, 4.7" x 2.2") with a T1/E1/J1 interface. A 
daughterboard can be mounted to make it a dual T1/E1/J1 card or 
to provide other features related to signal processing. The 
3.3v/5v PCI card optionally supports full channelization of the 
DS0s, making it ideal for multichannel hub implementations and 
integration with PCI-based VoIP PBX systems. The flexibility of 
the AFT platform allows easy upgrades to support different Telco 
interfaces and line speeds. Upgrades of the A101 will soon be 
available with hardware-based ATM and SS7 MTP2 support. 

"The A101 allows us to offer a new price/performance standard 
that none of our competitors can match," says Sangoma 
Technologies President and CEO David Mandelstam. "We expect to 
both dominate and expand the integrated T1/E1 connectivity 
marketplace based on our price and unparalleled technology. The 
card's 2U form factor and low power requirements make it ideal 
for OEM Internet Server and voice applications." 

The AFT range of cards is based on programmable hardware 
technology that uses Field Programmable Gate Arrays (FPGAs) to 
efficiently handle the line protocols in hardware. New 
self-configuring drivers to be released with the A101 automate 
the process of line and protocol set-up. 



"The new A101 has an excellent feature set," adds Nathan 
Whittacre of Whittrio, Inc., a Las Vegas-based system integrator 
and service provider. "Most impressive is the size of the new 
card, which allows us to install it into a smaller chassis. 
Sangoma Technologies offers an impressive line of high-speed data 
products for the PC platform, allowing us to be extremely 
creative with the installations to our customers. It has brought 
enterprise quality networking into the budget of small and medium 
sized businesses."
