Luminous Joins Sonus' Open Services Partner Alliance to Offer Carrier-Class

Voice and VoIP Metro Solutions



Apr 16, 2001, 01:00 ET from Luminous Networks

    CUPERTINO, Calif., April 16 /PRNewswire/ -- Luminous Networks, the first
 provider of carrier-class optical Ethernet platforms for Metropolitan Area
 Networks, today announced that it has joined the Sonus Networks (Nasdaq:   SONS)
 Open Services Partner Alliance to provide carriers with a cost-effective,
 carrier-class voice and VoIP solution.  The relationship with Sonus has the
 potential to revolutionize services provided by today's telecommunications
 carriers, as it allows them to offer multiple voice and data services from a
 common platform.
     This combination provides carriers with the first toll-quality,
 carrier-class voice and VoIP capability on an optical Ethernet metro platform.
 Luminous' optical Ethernet platform transports aggregated time-division
 multiplexing (TDM) data traffic through Metropolitan Area Networks (MANs).
 The Luminous platform then sends the TDM and VoIP traffic to Sonus
 softswitches and SS7 signaling gateways via the Sonus GSX9000 Open Services
 Switch for integration into the public switched telephone network (PSTN) and
 other voice network systems.
     "We are delighted to work with Luminous to help deliver carrier-class
 voice, VoIP, video and data services on a common optical Ethernet platform in
 Metropolitan Area Networks," said Terri Griffin, vice president of marketing
 programs, Sonus Networks.  "With the addition of Luminous to our partner
 program, Sonus continues to pursue its goal of empowering standards-based
 interoperability between multiple network applications and Sonus products."
     Alex Naqvi, president and CEO of Luminous Networks, added, "As a key
 architect of VoIP infrastructure solutions for the new public network, Sonus
 helps carriers reduce equipment costs, minimize physical co-location space,
 and deliver new revenue-generating services.  The combination of Luminous'
 optical Ethernet platform and Sonus' softswitch solution will improve network
 reliability, and increase scalability and performance for IP-based voice and
 data applications."
     Sonus, a leading provider of voice infrastructure products for
 telecommunications carriers, is at the forefront as the $60-billion legacy
 circuit-switch market migrates to an IP-based  market that transports voice
 and data over the same packet network.  Packet networks are comprised of
 softswitches and Sonus is a leader in the softswitch market that IDC estimates
 will grow from roughly $1.3 billion in 2001 to $5.7 billion in 2004.
     Luminous also announced today that it has joined Sonus Networks' Open
 Services Partner Alliance (OSPA), which helps speed the creation of
 next-generation, integrated solutions for carriers and service providers.  The
 goal of the OSPA is to empower standards-based interoperability between
 applications, hardware vendors and the Sonus product family.  The initiative
 is designed to create integrated solutions for carriers and service providers
 by formalizing independent interoperability testing of third-party products
 with Sonus solutions.
     Luminous Networks provides carrier-class voice and data solutions for
 Metropolitan Area Networks, based on its innovative Resilient Packet Transport
 (RPT) technology, an IP-optimized optical access solution that is
 significantly more efficient than systems burdened with technologies developed
 exclusively for carrying circuit-switched voice traffic.  RPT provides
 telecommunications carriers with support for differentiated data services,
 static and dynamic routing in a single box, scalability, network
 survivability, as well as carrier-class voice services.  RPT is fundamentally
 less complex for network management, ensuring rapid installation and fast
 revenue generation.
     Luminous Networks' PacketWave(TM) optical access switches enable
 Metropolitan Area Network service providers to offer a rich set of IP and
 legacy circuit-based services, all on the same network for transport of TDM
 voice, VoIP, video and data traffic in an efficient and cost-effective manner.
