AVM selects Lantiq technology for its new VDSL and Wi-Fi 11AC flagship gateway

LanTIq VDSL solution will be FRITZ! Box 7490 brings powerful power, and with the help of intelligent acceleration that can offload the CPU, the maximum data rate reaches 150Mbps

Munich / Nubiberg, Germany-October 18, 2013- Leading broadband access and home network technology provider Lantiq (LanTIq) has announced that the Berlin-based communications specialist AVM has selected LanTIq Integrated system-on-a-chip (SoC) is the latest generation of VDSL2 / 2 + flagship gateway FRITZ! Box 7490 provides processing power.

LanTIq VDSL SoC can support the highest data rate and stable broadband performance, and has VDSL2 / 2 + / ADSL2 / 2 + broadband, and includes ITU-T function enhancements such as Vectoring to provide data rates up to 150Mbps. With Lantiq's unique intelligent acceleration engine, the minimum CPU load can be achieved, and FRITZ! Box 7490 can even achieve excellent Gigabit routing performance.

comment

Peter Faxel, AVM ’s executive vice president of products and technology, said: “Lantiq provides high-end technology that perfectly meets the performance needs of our top models. Therefore, our customers will enjoy the superior quality of their broadband connections. Various benefits from our work. Our work based on Lantiq ’s VDSL / ADSL solution allows us to provide high-end VDSL gateways with excellent gigabit routing performance. "

Dirk Wieberneit, Senior Vice President and General Manager of the Client Equipment (CPE) Business Unit at Lantiq, said: "With our ultra-fast vRX VDSL chipset, we enable our customers to provide DSL gateways with unprecedented routing traffic at the highest data rates. Our VDSL chipset enables broadband equipment suppliers to flexibly produce routers and gateways. These devices can support various advanced customer services, and the number of components is less than any other available chipset solutions, while providing the best Quality Service (QoS). "

Highlights and benefits

· Lantiq's VDSL Vectoring solution in compliance with ITU-T standards enables operations to provide access rates of up to 150 Mbits. Accordingly, PHY Layer Retransmission also achieves the highest possible quality of service (QoS) for media content ).

· The high-performance data processing based on Lantiq's XWAY ™ VRX VDSL SoC offloads the 11AC Wi-Fi subsystem and minimizes the load on the main CPU.

Supply

Lantiq is now shipping large quantities of its XWAY â„¢ VRX series, and Fritzbox! 7490 is commercially available.

Applications:

The Grounding Transformer is a kind of auxiliary transformer that used to offer an earth point for the Delta-Star system. They are typically used for providing a path to ground for unbalanced load current and for fault currents on system where a suitable ground is otherwise not available.

Design:

The grounding transformers are generally designed with one of the two configurations: Zig-Zag (Zn) with or without an auxiliary winding or a Wye (Ynd) with a delta connected secondary. The Zig-Zag connection is preferred as it is more cost effective and have smaller size than the Delta-Wye unit. For more safety, neutral earthing resistors (NER) are often used in conjunction with the grounding transformer to limit neutral ground fault current magnitude. The rated voltage of the NER should be equal to the line to ground voltage of the grounding transformer. The current rating and duration should match the grounding transformer
