Arcom Selects Sangoma Technologies To Equip Hardened
Edge Router

TORONTO, ONTARIO--(CCNMatthews - Jun 2, 2004) -  

Sangoma's S5145 56K DDS and A101 T1/E1 cards enable easy 
integration and deployment of networking appliances to power and 
utility markets 

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 been selected by Arcom 
(www.arcom.com) of Kansas City and Cambridge UK to integrate 
Sangoma's S5145 56K DDS and new A101 T1/E1 cards into its series 
of environmentally hardened communications appliances. 

Arcom, a manufacturer of embedded operating systems, 
communications gateways and system designs for the power and 
utility industries, will deploy the Sangoma cards into its 
hardened edge routers running on the embedded Linux operating 
system. 

"Our devices are often used in very harsh environments with 
temperatures ranging from well below zero to just around 
boiling," says Arcom's PCP Sales and Product Manager Kurt 
Hochanadel. "As a result, we need robust components for our 
devices. In our trials with several leading North American power 
and utility organizations, we have had great success embedding 
Sangoma's cards into our product line due in large part to the 
superiority of their products as well as the quality of their 
drivers." 

Arcom's appliances are usually placed in remote areas where they 
have to go without on-site maintenance for long periods of time 
and endure extreme temperature changes. A typical application is 
remote meter monitoring for power utilities, an industry segment 
in which Arcom has found a market niche. The appliances including 
the Sangoma cards have successfully completed environmental 
testing in the laboratory and long-term field-testing with 
customers. 

"Arcom's channel agreement with one of the world's largest 
telecommunications outsourcing companies will help drive the 
market and create growth opportunities for our cards," adds 
Sangoma Technologies president and CEO David Mandelstam. "Arcom 
is clearly looking for robustness and simplicity. Our cards 
enable it to deploy a single ruggedized combination router and 
firewall solution, for maximum reliability in these demanding 
environments." 

Sangoma Technologies' current solution set includes: 

- High performance and reliable communications modules for OEM 
projects involving ATM, Frame Relay, X.25, SS7, HDLC, BiSync and 
other protocols 

- WANPIPE(R) internal IP routing solutions over T1, E1, ADSL and 
serial links 

- The WAN Edukit(TM) protocol teaching tool for educational 
institutions 

- POS (Point-of-Sale) interface cards for security and customer 
loyalty applications
