AT&T Deploys Distributed Antenna for Resort Coverage

AT&T has deployed a distributed antenna system (DAS) from TE Connectivity to provide coverage at The Broadmoor resort in Colorado Springs, Colorado. The installation includes 75 remote antenna units (RAUs) which are fed by a base station deployed by AT&T's Antenna Solutions Group, providing on-site network capacity for AT&T customers using the 850 and 1900 MHz frequency bands.

TE Connectivity is a preferred partner of AT&T's Antenna Solutions Group, which is using DAS to enhance mobile coverage at major resorts, stadiums, hotels, and other premium properties around the United States.

NTT Makes Progress in Restoring Services in Quake Zone

Thanks to the efforts of thousands of employees and construction workers, NTT has restored service approximately 90 percent of the exchange offices damaged in the March 11th earthquake, leaving 93 exchange offices and approximately 155 thousand circuits waiting to be restored.

The March 23rd status of disaster relief efforts being made by NTT Group companies is as follows:

The earthquake and tsunamis disrupted commercial power supply and caused equipment failure in approximately 1,000 exchange offices. NTT East responded by deploying emergency batteries, emergency power generators and mobile power-supply vehicles to supply power. However, some exchange offices remained inoperable, resulting in the disruption of a total of approximately 1,470 thousand circuits in telephone subscriber lines, ISDN and FLET'S Hikari (FTTH) services as of 6:00 a.m., March 13 (JST). NTT East, with the help of other NTT group companies and construction companies, comprised some 5,000 people in total, to make an all-out effort to restore these services.

The 93 exchange offices yet to be restored include those with physical damage, flooding or disruption of connection to backbone transmission lines in areas severely impacted by the earthquake and/or tsunamis, and those located in the off-limits area surrounding the malfunctioning nuclear power plant. For these reasons, the recovery of most of these exchange offices is expected to require a significant amount of time.

NTT East has installed 2,076 special public telephones in 615 locations available for use free of charge (as of noon, March 23 (JST)).

For NTT Docomo, 6,720 base stations were disrupted. Recovery efforts have reduced the figure to approximately 840 as of 1:00 p.m. on March 23 (JST).

NTT Communications lost approximately 15,000 IP-VPN and e-VLAN circuits and so far all but 2,300 have been restored.

The company also noted some damage to submarine cables and backup routes were put into service. As for NTT Com's data centers, no damages were confirmed.

Etisalat Deploys Verimatrix for IPTV in UAE

Symmetricom Delivers Precise Timing for Packet Backhaul

Symmetricom introduced its "TimeProvider" 1500 (TP1500) packet-based primary reference source (PRS) clock, which can be used in Carrier Ethernet packet backhaul networks as a complement to a traditional cesium clock or a global navigation satellite system (GNSS) antenna installation.

Symmetricom's TP1500 combines the rubidium QUANTUM miniature atomic clock (MAC) and its "PackeTime" technology to deliver primary reference level synchronization in areas where GNSS coverage or antenna deployment is challenged, and supports migration from TDM to Ethernet-based networks. The TP1500 adheres to the IEEE 1588-2008 protocol specification, and leverages the capabilities of its TimeProvider 5000 Grandmaster to provide packet-based PRS services for the radio access network (RAN). The TP1500 product is part of Symmetricom's TimeProvider suite of products that are based on the IEEE 1588-2008 standard.

"The TP1500 is the industry's first packet-based primary reference source solution to enhance traditional synchronization sources," said Manish Gupta, vice president of marketing at Symmetricom. "The TP1500 is another example of Symmetricom's innovative approach to solving customers' challenges, providing a unique packet-based solution that is immune to the interference and antenna deployment challenges of traditional GNSS sources."

cPacket Puts Timestamping Code into Public Domain

CPacket Networks is placing in the public domain a new solution for accurate timestamping of high speed network traffic in real-time.

cPacket provides accurate real-time information by timestamping the applications data on the fly directly "at the wire," before queuing, buffering, or aggregations can alter its timing behavior.

CPacket said its new software enables users and application developers to seamlessly integrate such real-time timestamping into existing solutions, or into open source tools like Tcpdump, Wireshark, and n2disk. When used with hardware timestamping directly at the wire, this software enables any application to take full advantage of the most accurate inline timestamping in a standard format (including pcap, libcap, etc.). The standard format and seamless integration means no changes to the user's application software are required.

cPacket makes this new software and driver available free of charge in the public domain to customers, application developers, other solution vendors, universities and the open source community.

TE Connectivity Wins $400 Million Contract with Australian NBN

This wholesale agreement will enable Open Range to sell LightSquared's next generation satellite capacity. The partnership will also include a 4G nationwide reciprocal roaming arrangement. Under the arrangement, the companies will collaborate on the design, build-out and operation of Open Range's network as well as on product and service evolution

Continuous Computing's ATCA DPI Platforms Tops 320 Gbps

Continuous Computing released its latest FlexTCA integrated platform for deep packet inspection (DPI) network intelligence applications.

Continuous Computing's FlexTCA, which is based on the latest 40G ATCA standards, combines switch, packet processing and compute products. It capitalizes on the company's FlowEngine DPI software framework, which combines the advanced load balancing and packet processing capabilities of an ecosystem of software vendors and the customization capabilities of professional services companies into a package that provides NEPs the complete foundation on which they can build and market advanced DPI applications.

The FlexTCA DPI platform is the first to come with native 100GbE interfaces – dual 100GbE CXP with active/standby capability and the option to aggregate other interface types (e.g., 10GbE SFP+ or 40GbE QSFP) for maximum speed.

Policy enforcement and monitoring have become critical elements of assuring performance in today's bandwidth-constrained networks, and DPI is the key enabling technology," said Mike Coward, chief technology officer and co-founder of Continuous Computing. "With the skyrocketing increase in network traffic from advanced, bandwidth-hungry content like converged voice and video, packet processing solutions need to be able to mirror the resulting massive increase in throughput requirements. With up to 320Gbps system capacity, FlexTCA is the right platform at the right time."

The new FlexTCA platform family includes:

  • Option of 14-, 6- or 2-slot platforms, all of which support 300W+ blades

  • FlexCore™ ATCA-FM81 hub switch supporting 10GbE, 40GbE and 100GbE interfaces

  • FlexPacket™ ATCA-PP81 DPI blade with dual NetLogic Microsystems XLP832 CPUs

  • Optional hardware offload includes NetLogic NL11K KBP (Knowledge-based Processor) TCAM and specialized NetLogic NETL7 NLS2008 RegEx solutions for pattern matching

  • FlexCompute™ ATCA-XE100 compute blade with the latest Intel microprocessors.
