October 29, 2007 -- ZyXEL Communications has extended its ADSL product line to include a bonded ADSL2+ CPE router and support for bonded ADSL2+ to ADSL2+ line cards for the company's MSANs (IES6000, IES5000 and IES5005) and standalone ADSL2+ DSLAMs (IES1248 Series).
According to the company, by utilizing ADSL2+ loop bonding, a service provider can combine two existing copper phone lines into a single connection that delivers high-bandwidth access. Via this method, carriers and service providers gain the advantage of a quick, low-cost way to reach more subscribers with advanced broadband services such as VoIP, IP television (IPTV), and triple-play bundles of voice, data, and video.
ZyXEL's bonded ADSL2+ CPE offering, the P663H-51 modem router, will support speeds of up to 48 Mbit/sec downstream and 4 Mbit/sec upstream and include four 10/100 Ethernet LAN ports. Other capabilities include support for TR069 protocol for remote management, SPI firewall, and DOS protection for security and advanced QoS and multicasting features for triple play.
"We would like to offer service providers all the options for broadband access, including ADSL2+, bonded ADSL2+, VDSL2, G.SHDSL and PON so they can choose the solution that best meets their needs," comments Munira Brooks, senior vice president of sales, marketing and business development for ZyXEL. "With bonded ADSL2+ support, now carriers with original ADSL2/2+ technology will be able to offer high bandwidth services to their subscribers without additional investment."
In general, bonded ADSL2+ technology provides high-speed connections for rich media services to customers otherwise out of reach because of their distance from the central office or DLC (digital loop carrier). Multiple streams of high-definition television can be supported using bonded ADSL2+. Carriers can use bonded ADSL2+ in rural areas where copper is much more prevalent and fiber has not been fully deployed; bonded ADSL2+ technology can help maximize the bandwidth and performance opportunities of the "last mile."
The RUS-approved ZyXEL multi-service access node (MSAN) and IP/DSLAM offers a range of options for Fiber to the Neighborhood/Curb (FTTx) deployments. Available in different configurations, the company's IES6000, IES500 and IES5005 products offer line card support for ADSL2/2+, VDSL2, G.SHDSL and POTS/VoIP services.
Additionally, the company's MSAPs support non-blocking Gigabit Ethernet backplane, Gigabit Ethernet ports for uplink including SFP fiber interfaces, advanced QoS, and multicasting features for triple play services and failover-enabled management features. The product line also includes hardened 48-Port ASLA2+DSLAM in the form of the IES1248; and a 16-Port VDSL2 switch, the IES-1616, with an integrated POTS splitter that is ideal for FTTC and FTTB deployments.
