Denver - Allied Telesyn Inc., a longtime leader in stacked Ethernet switches, is venturing into the digital subscriber line, metro Ethernet, managed router and residential gateway markets. Its "triple play over DSL" offering will bring voice, video and data services to smaller rural carriers requiring DSL solutions from both the central office and remote terminals.
Allied Telesyn (Bothell, Wash.) is partnering with GlobespanVirata for that company's ADSL solution and with Broadcom Corp. for a backplane-oriented Ethernet switching fabric.
Chief executive officer Howard Kammerer said Allied Telesyn is fully prepared to meet and beat Cisco targets for products appealing to smaller carriers and to small and medium-size businesses in the access market. The triple-play systems debuting this month will be offered not just to rural independent carriers but to a variety of incumbent and competitive carriers as service provider markets return to health.
Allied intends to use its experience in Ethernet and Internet Protocol to deliver DSL solutions that offer the quality-of-service granularity of asynchronous transfer mode switching, but without the ATM interfaces commonly seen in DSL systems. Chief technical officer Phil Jopa said the company has worked on advanced video provisioning using unique mechanisms, such as ADSL line training based on "errored seconds," for more dependable delivery of multiple digital TV services.
The company also says it has improved the handling of Internet Group Management Protocol for multimedia, collating and grouping together IGMP so that DSL access multiplexers are not clogged with redundant IGMP traffic.
The 7400 DSLAM for remote cabinets and 7700 DSLAM for central offices both use a star architecture backplane and support up to 512 multicast video channels. The environmentally hardened 7400 has seven card slots, while the 7700 has 17 slots. Both are NEBS-hardened and can be equipped with dual power supplies. Allied is working with server and transport-system partners such as Minerva Networks, Myrio, NetInsight, RCA and Tut Systems to offer end-to-end multimedia systems.
