New Comcerto 300xv by Mindspeed Selected by ZTE Corp.

Updated: January 07, 2011

 Mindspeed Technologies, Inc. has just developed a new product: the Comcerto 300xv family of VoIP processing devices. Comcerto 300xv uses the company's multi-core Comcerto 300 architecture. This architecture includes support for master/slave modes and multiple booting methods, and is flexible enough to let customers easily differentiate their products. The turnkey device is supported by a reference design package that includes an open-source SIP signaling stack and low-level board support packages.

The device's OpenWrt-based Linux design kit lets customers access hundreds of applications and create a functionally complete routing program, and the software can support wideband voice codecs for high-definition VoIP applications. The Comcerto 300xv device involves two ARM processors, one of which is paired to DSP resources and integrated memory to optimize real-time, low-latency voice processing, and the other of which is dedicated to CSP functions. The two processors are coupled through shared memory to create a media stream processing substream. The inclusion of these two independently configurable interfaces lets the product support a wide range of configuration options, allowing direct control and management of Ethernet switches or passive optical networking (PON) media access control. The Comcerto 300xv software reduces bill of material costs for price-sensitive platforms like multi-dwelling unit equipment, IP-PBX systems, and PON.

The Comcerto brings several advantages to PON platforms. Mindspeed recently announced that “ZTE Corporation, a leading global provider of telecommunications equipment and network solutions, has selected Mindspeed’s Comcerto 300xv...for use in ZTE’s xPON access products.” ZTE is China's largest listed telecommunications manufacturer. Mr. Chen Hairong, hardware director of ZTE's Network Department, described his reasons behind the purchase: “Today’s users increasingly demand higher levels of service from the telecommunications provider. By utilizing the Comcerto 300xv, ZTE is able to provide the large-capacity, high-speed, wide-bandwidth and high-quality data, video, voice and multimedia services necessary to address these demands.” The Comcerto 300xv is scheduled for volume production in the second half of 2010.
