Central Scott upgrades with Occam Networks to offer new broadband services, GPON systems
MAY 19, 2010 -- Occam Networks Inc., a broadband access supplier offering multiservice access platform (MSAP) systems based on pure packet technologies, announced that Central Scott Telephone in Eldridge, Iowa, has deployed Occam solutions in two upgrade projects.Central Scott is upgrading its DSL network to improve the quality of current voice and data services, as well as future video services to be offered. It is also completing a competitive fiber overbuild to make advanced services available to the neighboring Quad Cities area.Occam solutions replaced an existing non-carrier grade Ethernet ring that served Central Scott’s three exchanges, but lacked the capacity and flexibility to handle the VoIP service Central Scott introduced. The provider also had limited fiber facilities in its CLEC territory in Bettendorf and Davenport, Iowa, requiring it to lease capacity from other carriers to reach customers. After curing these quality issues, Central Scott expanded its services to include unserved areas, offering access speeds to its business customers of over 100Mbps for some.Central Scott also has completed a competitive overbuild into the Quad Cities area, home to more than 300,000 potential subscribers. Central Scott chose to deploy GPON service in Occam’s BLC 6000 MSAP and began offering 4-5Mbps service.Central Scott is serving the area’s anchor institutions, such as schools and government, as well as networking several medical facilities with connections as fast as 100Mbps. These new rings are connected to Iowa Network Services (INS), an organization of 127 independent telephone companies that operates a statewide fiber optic network.
ZyXEL launches dual-WAN, multi-service, VDSL2 FTTN/FTTH gateway
MAY 18, 2010 -- ZyXEL Communications Inc. has announced the P2812HNU, a single gateway that supports copper, fiber-to-the-node (FTTN) and fiber-to-the-home (FTTH) deployments.The P2812HNU, with dual-WAN, offers a range of connectivity options. An integrated VDSL2 modem enables service providers to support up to 100/50 Mbps over newer PTM networks -- along with ADSL2+ fallback to accommodate existing networks. The gateway also has a dedicated Gigabit Ethernet WAN port for FTTH deployments.In addition to broadband access, the P2812HNU acts as a home networking unit with 300-Mbps 802.11n wireless, four Gigabit Ethernet LAN ports, and two SIP-based VoIP ports. On the management side, the device supports TR-069 for remote management."The P2812HNU is one of our most versatile offerings," said Brian Feng, senior vice president of ZyXEL. "It offers operators multiple deployment, management and service options, including triple-play and VoIP."
Alcatel-Lucent Bell Labs ‘phantom mode’ pumps 300 Mbps over two DSL lines
APRIL 21, 2010 -- Alcatel-Lucent (Euronext Paris and NYSE: ALU) says that its research arm, Bell Labs, has successfully demonstrated a technology that boosts the transmission speeds achievable over two DSL lines. In a lab test of “DSL Phantom Mode,” Bell Labs achieved downstream transmission speeds of 300 Mbps over distances up to 400 m (or 100 Mbps at 1 km).The technology promises to enable service providers to maximize the transmission capabilities of existing copper infrastructure to support triple-play services “for years to come,” the company asserts.The DSL Phantom Mode involves the creation of a virtual or “phantom” channel that supplements the two physical wires that are the standard configuration for copper transmission lines. Bell Labs combines this mode with such standard techniques as vectoring (which eliminates crosstalk between copper wires) and bonding (which aggregates the capacity of multiple lines).“Alcatel-Lucent Bell Labs’ DSL Phantom Mode lab test adds a whole new dimension to the ongoing ‘100 Mbps for all’ debate. The fact that existing copper loops can facilitate 300 Mbps at 400 meters reshapes the whole next-generation broadband competitive environment -- and will open up a wide range of new business opportunities for ‘traditional’ DSL players,” comments Kamalini Ganguly, analyst from Ovum. “This announcement shows that Alcatel-Lucent is seriously looking at all possible innovations to help its customers speed up the deployment of next-generation access networks, through a smart mix of advanced copper and fiber technologies.”Further research is being conducted to refine deployment models and determine a specific set of customer premises equipment (CPE) models compatible with the DSL Phantom Mode technology. The company is not predicting when the technology will be commercially available.
