NTT's 2006 Plan Sees Shift from ADSL to Optical Access

Noting
the effect of wireless substitution, the rapid rise of VoIP, and
increased competition in both residential and business markets
from fixed line competitors, NTT East said it would accelerate
efforts to offer optical IP phone services. The company will
devote itself "to efficiently building optical access
networks as an infrastructure for broadband services and to
ensuring reliability in the field of telecommunications. "



In the coming year through March 2006, the actual number of ADSL
contracts at NTT East is expected to fall, while B-FLETS optical
connections reach one million circuits. For the ongoing optical
access build out, NTT East forecasting CAPEX of 170 billion yen,
up from 130 billion in the preceding year.

Similarly, NTT West sees the fiscal year ending in March 2006 as
critical to its strategy to achieve a dramatic increase in users
of its optical access and IP services. NTT West will also push
its Fiber-optic IP Connection service, aiming to have 800,000 B-FLET's
optical access subscribers by next March, up from 400,000 today.
Its number of ADSL subscribers is also forecast to fall due to
the move to optical access.



NTT West plans to spend 160 billion yen for the optical access
build-out through March 2006, up from 150 billion yen this year.

http://www.ntt.co.jpIn November 2004, Japan's NTT Group outlined its plans to migrate a majority of its customers to a next generation optical access and IP telephony network by 2010. This "medium-term management strategy" is aimed at advancing the company's long-term "Vision for a New Optical Generation," which NTT first disclosed in November 2002. Some specifics of the plan included:

  • NTT intends to migrate the majority of its customers to an optical access network by 2010, taking into account the interests of customers and operators of related businesses. The company said maintaining both metal wire and optical fiber access and fixed telephone networks, as well as IP networks, is a burden on business operations and increases the cost to society.

  • NTT will promote IP telephone services as an alternative to fixed line service and provide a variety of ubiquitous broadband services emphasizing high-speed and interactive features in order to shift 30 million customers from the existing metal wire and fixed telephone network to optical fiber access and next-generation network services by 2010.

  • NTT will move to a flat-rate pricing structure which is not based distances, that gives customers service options that meet their requirements for quality, speed (data volume), reliability and security levels, and with varied rates depending on service content.

  • NTT is currently reevaluating its existing fixed-telephone rates (basic rate, call rates, equipment installation rates) in light of the eventual move to IP telephony. It plans to announce a revision to its basic rates and other fees as a first step in this direction.

  • NTT will promote Fixed-Mobile Convergence, whereby high-speed interactive video communications over optical fiber will be combined with mobile communications services to provide ubiquitous services that can be accessed from PCs, TV sets, mobile telephones or information appliances. Its next-generation network will be based on a common service foundation that merges mobile and fixed communications. Each NTT group company will fill a role that plays to their strengths.

Agilent Shows 10 Gbps XENPAK Over 300m of MM Fiber

Agilent Technologies will demonstrate a 10 Gbps XENPAK fiber optic transceiver transmitting network traffic over 300 meters of multimode fiber at next week's OFC/NFOEC 2005. The demonstration will show Agilent's XENPAK fiber optic transceiver module, featuring EDC, transmitting a 10 Gbps data stream error-free over a distance of 300 meters using legacy multimode FDDI grade 62.5/125 micron fiber. The fiber optic cable will be flexed to vary optical signal polarization and stress the EDC's ability to accommodate a variety of incoming signal characteristics.


In addition, Agilent's Fiber Optic Products Division and Input/Output Solutions Division will demonstrate a 4 Gb/s optical link using its 4G multimode (MM) and single-mode (SM) Fibre Channel optical transceivers and 4G Tachyon Protocol ICs. The demonstration will showcase a PC server generating 4G traffic through an HBA initiator (using Agilent's 4G IC and 4G MM and SM transceivers) to a loop switch (using Agilent's loop switch IC and 4G MM and SM transceivers) that will send 4G traffic to an HBA target.


Agilent is leading the IEEE 802.3aq task force, which is defining a standard for using electronic dispersion compensation (EDC) with 10 Gbps serial Ethernet fiber optic transceivers to economically drive short-range transmissions over legacy multimode fiber. Corporate IT departments are demanding a cost-effective solution for the existing enterprise LAN infrastructure before widespread upgrades to 10 Gb Ethernet are implemented.

Intel Outlines I/O Acceleration Technology

Intel outlined a set of silicon technologies that speed the interaction between network data and server applications by up to 30%. Intel also announced an agreement with Microsoft to support the technology in forthcoming operating systems. The Intel I/O Acceleration Technology (I/OAC) takes a platform approach to address the application performance issues -- such as Web commerce, messaging, storage and server clustering, which are beginning to overwhelm servers' responsiveness.


Intel said that while server CPU performance and network bandwidth has improved over the years, the primary method for moving data has not changed. Today, the processor in a server shoulders the total burden of processing, accessing memory and making protocol computations on every piece of data or packet. As a result, much of the processor's operation is diverted and response time, reliability and the end-users' experience can suffer.


The Intel I/O Acceleration Technology would break up the data-handling job among all of the components that make up the platform -- the processor, chipset, network controller and software. This would reduce the workload on the processor while accelerating the flow of data. The chipset and network controller would be given responsibility for moving data in and out of memory.


Intel has also optimized the TCP/IP protocol for Intel-based servers, which cuts the processor's workload in half, further freeing it to work on other jobs.


Intel said this new platform approach would remedy inadequacies in existing technologies, such as TCP offload engines (TOE), designed to offload the processor of TCP/IP processing. TOE dedicates a specialized and costly chip to offload the protocol computation, but it does not fully address system overhead or memory access, the two largest burdens on the CPU. As a result, TOE is effective only when packets payloads are large, such as those in high-performance database and data-warehousing applications.


Microsoft will provide native support for Intel I/OAT in future Windows Server releases. Those releases also will include technology that balances network TCP/IP traffic streams across multi-core CPUs.

General Bandwidth Raises $18 Million in New Funding

General Bandwidth raised $18 million in new financing for its VoIP equipment. General Bandwidth supplies its G6 Universal Media Gateway platform, which is a carrier class VoIP services platform with the capability to simultaneously support multiple service architectures including legacy Class 5 switches, SIP-based feature servers, and next generation softswitches. The platform is currently being used by more than 40 customers.


Oak Investment Partners led the new round with participation from Sevin Rosen, Venrock Associates, Invesco, Thomas Weisel Capital Partners, Trellis Partners, Star Ventures, Wheatley Partners, HLM, Protostar, Granite Global, Siemens Venture Capital and Texas Instruments. http://www.genband.com
  • In February 2005, General Bandwidth introduced its G6 Reverse Media Gateway designed to enable legacy remote terminals, such as wireline Digital Loop Carriers (DLCs) and cable Host Digital Terminals (HDTs), to migrate from Class 5 call control to IP-based softswitch call control.

  • General Bandwidth said remote terminals using GR-303, TR-08 or V5.2 circuit technology until now have been islands set apart with no effective means of connecting to the new IP-based features and benefits of packet switching technology. Wireline network DLCs and cable network HDTs connect to Class 5 switches over standard GR-303, TR-08 and V5.2 interfaces. With the G6 Reverse MG, these interfaces can be migrated to the G6 platform, using DS-1/E-1 or DS-3/STS-1 connections between the G6 and DLCs/HDTs.

  • General Bandwidth, which supplies a VoIP Media Gateway, named Charlie Vogt as its new president and CEO. He replaces Brendon Mills, who is stepping down. Vogt previously served as President and CEO of Taqua, a supplier of a Class 5 softswitch. Charlie was part of the executive management team with Santera Systems, a Plano, Texas-based developer of a next-generation voice switching technology that was acquired by Tekelec. Prior to Taqua and Santera Systems, Vogt held senior management positions at Accelerated Networks, Ascend Communications, ADTRAN, Motorola and IBM.

  • General Bandwidth raised over $180 million in its previous rounds.

  • In April 2004, it was announced that Alcatel had invested US$15 million in General Bandwidth. The investment further strengthened the three-year OEM relationship between the two companies and allowed for additional development enhancements to their joint FTTP and VoIP offerings.

Cox Selects Nortel for Circuit Switch to VoIP Migration

Cox Communications and Nortel outlined plans for evolving Cox's existing circuit-switched telephony networks to a hybrid TDM/VoIP model. Key points of the plan, which builds on a relationship first announced in 2003, include:

  • Cox currently serves 1.2 million residential and 100,000 business telephony lines in 17 markets across the U.S. It first launched local phone service in Orange County, California in 1997.


  • Cox is currently using two dozen circuit switches to provide these primary line services.


  • Cox is already using VoIP to carry long distance traffic over its national IP backbone and is deploying softswitches in its new VoIP local markets.


  • In this recent deal, Cox has agreed to upgrade at least 10 DMSs to the Nortel Communication Server 2000, expecting to bring more than 50% of its new growth lines to VoIP by the end of 2005.


  • The PacketCable-compliant Nortel Communication Server 2000 solution, integrated with Nuera Communications BTX Gateways, will enable Cox to offer the same quality telephony services that residential and business customers have come to expect from Cox and will position Cox to add rich multimedia services in the further, enhancing the communication capabilities of these Cox customers.


  • There are six steps to the migration -- upgrade the circuit switches to the required hardware baseline to support VoIP; upgrade the core software to a VoIP-enable load in an overnight process; add media gateway controller blades, media gateways and other VoIP hardware; establish connectivity to the VoIP-ready IP bearer network; reconfigure operating system applications to support VoIP; complete pre in-service testing.


  • Cox believes it is more cost-effective to evolve the majority of its circuit switches to hybrid TDM/VoIP than to overlay new softswitches in the existing TDM markets.

  • In June 2004, Cox Communications awarded a multiyear contract to Nuera Communications Inc. to provide media gateways for its nationwide VoIP deployments.


  • In May 2004, Nortel Networks agreed to integrate, sell and support VoIP gateways from Nuera Communications as part of an integrated PacketCable qualified solution.
