TOLLBRIDGE TECHNOLOGIES AND COPPER MOUNTAIN NETWORKS FORM TECHNOLOGY AND MARKETING PARTNERSHIP
Two Companies Partner to Deliver Toll-Quality Multiline Voice-over-DSL Solutions to Existing and Prospective CLEC Customers Sunnyvale and Palo Alto, Calif., June 1, 1999 - - TollBridge Technologies and Copper Mountain Networks (NASDAQ: CMTN) announced today a technology and marketing partnership for delivering IP-based multiline voice over Digital Subscriber Line (DSL) broadband access. The two companies have tested the interoperability of their respective product families to ensure that the integrated solution delivers toll-quality voice in the local loop. The companies are marketing the joint solution to their respective customer bases: voice and data Competitive Local Exchange Companies (CLECs) seeking LEC bypass strategies for attracting small and mid-sized business subscribers. In addition, TollBridge is licensing its TollVoice technology to Copper Mountain for integration into Customer Premise Equipment (CPE). TollBridge and Copper Mountain are working together to develop reference-standard CPE designs to license to Copper Mountain's CopperCompatible partners to accelerate the broader availability of CPE products that interoperate with the TollBridge-Copper Mountain solution.

"Copper Mountain's DSL platform has been deployed in the largest data CLEC broadband access networks nationwide," said Jim Grady, TollBridge vice president of marketing. "By partnering with TollBridge, Copper Mountain offers its customers a way to improve the return on their DSL infrastructure investment by offering voice services to small businesses over DSL access lines. Small businesses currently have no competitive alternative to the LEC for voice service today, and pay the highest prices of any voice customer. These businesses represent a $46 billion opportunity for voice services." "Now that our customers have built out their nationwide DSL networks, they are ready to add advanced services to the dedicated data services currently delivered through the Copper Mountain platform," said John Reister, director of product marketing at Copper Mountain. "The TollBridge solution naturally interoperates with Copper Mountain products to enable our data CLEC customers to partner with voice CLECs to offer toll-quality voice services to their subscribers, to reduce customer churn, and to increase potential revenue per DSL. In a market as competitive as the local loop, the carriers that are first to deliver value-added, bundled services should have a strong advantage." Packet-Based End-to-End
The TollBridge-Copper Mountain voice-over-DSL solution provides new operational efficiencies for voice in the local loop because it is IP packet-based from end-to-end. TollBridge's TollVoice architecture packs samples from multiple voice calls into a single IP packet and transmits voice along with end-user data traffic over the broadband DSL link. Unlike the H.323 protocol, the TollVoice multiline-per-packet solution ensures the most efficient use of network resources. TollVoice prioritizes voice over data to ensure the bandwidth is available to provide toll quality. To deliver full-featured voice, the TollBridge system uses only the voice coding standards and rates supported by the Class 5 digital telephony switch. Taking advantage of the ample bandwidth available through DSL, the TollBridge solution supports full-rate 64 kbps and 32 kbps voice. The TollBridge TollVoice architecture can support up to 24 lines of voice on a single DSL copper pair. As part of the partnership agreement, TollBridge and Copper Mountain are developing ways to increase the efficiency of the network to support even more voice traffic per DSL link. At the customer premise, the TollBridge TB50 CPE interfaces to the Copper Mountain CopperRocket DSL CPE, or any other CPE that is certified by Copper Mountain as CopperCompatible. To date more than a dozen CPE devices-including the TollBridge products-have been certified. Copper Mountain initiated the CopperCompatible interoperability program to ensure service providers and DSL users could have multiple competitive sources for innovative, compatible CPE. Through this program, other CPE vendors can benefit from the TollVoice technology licensed by Copper Mountain. When individual data streams reach Copper Mountain CopperEdge DSL concentrators at the local CO, the CopperEdge grooms and aggregates the traffic into a single data stream and delivers it over high-speed links to the data CLEC's regional data center. There, the voice traffic is passed on to the TollBridge TB200 Local Exchange Gateway at the voice CLEC's regional Point-of-Presence (POP). The TB200 unpacks the voice channels, converts them back into circuits, and passes the voice calls on to the Class 5 switch using the BellCore GR-303 protocol. "Because ICG already has a nationwide DSL network with NorthPoint Communications and Copper Mountain DSL equipment, we are currently testing a TollBridge-Copper Mountain configuration in our lab that would integrate a voice data solution without making substantial operational changes to our network," said Jon Lowry, senior director of ISP Markets at ICG Communications (NASDAQ: ICGX). "Such an integrated voice/data solution over SDSL could become a very cost effective method of delivering toll-quality voice services to new customers which ICG might not otherwise serve." "NorthPoint designed its network with cutting-edge technology in anticipation of supporting additional business-critical applications like voice services," said John Stormer, vice president of marketing at NorthPoint Communications (NASDAQ: NPNT). "We are excited about solutions like these that will allow our customers to offer high-quality voice and data over our advanced DSL network." About TollBridge Technologies
