Veraz Networks and ZyXEL Deliver End-to-End Mobile WiMAX Solution

Veraz Networks, Inc. (Nasdaq:VRAZ), a leading global provider of IP softswitch and media gateway solutions, today announced it has certified ZyXEL, a top provider of complete broadband access solutions for service providers, as well as business and home users, as a ‘Deployment-ready’ member of the Veraz Open Solution Alliance (VOSA). Together, the Veraz ControlSwitch™ and ZyXEL’s multi-service access node (MSAN) and integrated access devices (IADs) deliver a turnkey solution for operators seeking to grow new revenues and manage operating costs when deploying IP-based telephony services. Operators are seeking ways to quickly roll out new services through both IP access devices (IADs, WiMAX IADs, soft clients) and existing POTS terminals. New multimedia services required by end users can only be delivered with an IMS solution equipped with end-to-end SIP signaling. The Veraz ControlSwitch and ZyXEL’s CPE devices are providing an integrated, easily deployable, all SIP-based solution that enables providers around the world to quickly capitalize on new services. The Veraz/ZyXEL joint solution is already deployed in a tier-one carrier in Europe and in trial with a large incumbent carrier in Asia. The Veraz ControlSwitch provides operators with an extremely cost-effective switching solution, and broad interoperability due to its IMS standards-compliance. The Veraz Open Service Broker enables easy deployment of new services across access equipment. The ZyXEL access equipment--the IES5000 M / ST (Multi Service Access Node) equipped with VoIP Line Cards, ADSL Line Cards, and Management Switch Cards, and the P2302R-P1C, CPE equipment with rich call features, advanced quality of service, and built-in auto-provisioning server--enables a unified services experience across a multitude of access technologies (POTS, ADSL+, VDSL2, G.SHDSL) and also the most recent mobile WiMAX, while simplifying carrier deployments and shortening services adoption time at the end user side. "ZyXEL is a leader in CPE and a recognized pioneer in enabling mobile WiMAX access,” said Francesca Puggioni, Head of Corporate Business Development in Veraz Networks.
