Brazilian Provider Delivers Differentiated Services Using Avails Multiservice Access Platforms

Ann Arbor, Michigan, December 5, 2002 -- Avail Networks announced today that Mundivox Communications, a broadband telecom provider based in Rio de Janeiro, Brazil, has deployed Avails Frontera converged access platforms to serve their 1000th corporate client.

Mundivox continues to leverage its proven pay as you grow" strategy, adding new infrastructure to customer locations only when there is sufficient demand to justify the build-out. This strategy also entails partnering with leading solutions providers -- including Avail Networks, Cisco (NASDAQ: CSCO), Lucent Technologies (NYSE: LU), and Sun Microsystems (NASDAQ: SUNW) -- who provide cost-effective platforms that can grow with the customer base.

We continue to win new customers in spite of the challenging economic conditions," noted Alberto Duran, President of Mundivox. Mundivoxs success stems from our commitment to deploy equipment and services only where there is a strong business case, and Avails Frontera solutions support this strategy by providing us a way to offer integrated communication solutions simply and cost effectively."

Avails Frontera products serve as the edge devices that deliver multiple broadband services to 1000 Mundivox corporate clients in over 50 points of presence. Over the course of more than a year of deployment activities, Avail has become the key enabler of the Mundivox value proposition: to provide high quality, competitive, scalable, reliable, and easy-to-use services.

Mundivox delivers specialized network services tailored to meet our business needs," said Pedro Paulo Moreira, Latin America Enterprise Services Manager of Landmark Graphics Co. (a Halliburton company, located on the web at www.lgc.com). We appreciate having the option to add bandwidth and services as we grow our business, without having to purchase new equipment."

Mundivox is a great example of a provider focused clearly on business justification before building out their broadband access network," noted Dave Hartmann, President and CEO of Avail Networks. We are pleased that they continue to be successful in growing a satisfied enterprise customer base with our products."
