BLC 6000 Blades
BLC 6214 ADSL2Plus with Gigabit Ethernet, Integrated Splitter
The 6214 ADSL2Plus blade provides 48 subscriber ports using the latest ADSL technology to deliver data and video services. The ADSL2Plus service ports, combined with Gigabit Ethernet feeder transport capabilities position the 6214 blade as the DSL workhorse for the future of the access network.

Broadband consumer services are delivered over standard ADSL lines. The 6214 technology delivers the subscriber bandwidth needed for viable data and video services. The subscriber interfaces support the evolutionary range of off-the-shelf ADSL modems: ADSL G.lite, ADSL DMT, ADSL DMT with S=1/2, ADSL2, and ADSL2Plus. The 6214 acts as a gateway function between the standard ADSL ATM and native IP over Ethernet allowing seamless access network connection to IP routers, Ethernet switches and IP based digital video headend systems in the switch centers and core network.
The Gigabit Ethernet capacity of the 6214 provides the very high bandwidth required for video services. Network bandwidth must support hundreds of broadcast channels and also sustain the expected growth of Video On Demand. Even a moderate VOD service subscription rate can consume multiple OC-3s during peak viewing time. Each 6214 blade supports up to four Gigabit Ethernet optical fiber ports. A single port can be used to support initial requirements, and additional GigE ports brought on line as the VOD service grows.
The core IP technology of the BLC 6000 includes Multicast IGMP in the 6214 and at every node in the network. This feature allows a subscriber request for a broadcast channel to join the stream at the closest point in the network that it exists. This capability preserves feeder bandwidth for VOD and data services, and it eliminates the need for separate IP processing or routers to be deployed.
Another advantage of the 6214 is streamlined network operation with digital video headend systems. The BLC 6000 system creates a native IP delivery network that removes the complexity of ATM transport. The BLC 6000 eliminates the overhead of transporting large video packets chopped into ATM cells. The BLC 6000 IP service delivery model includes edge aggregation that eliminates the virtual circuit provisioning of the ATM model.
The Gigabit Ethernet core of the 6214 is a high performance, wire speed Ethernet switch with ten ports. The Ethernet ports may be used for network transport, for blade interconnection or even Ethernet service delivery.
The 6214 blade can be deployed standalone as the BLC 6214 assembly, or it can be used in high-density deployments with other BLC 6000 blades in the BLC 6012 High Capacity Chassis. The single blade BLC 6214 assembly may be stacked with additional units to add capacity and hardware redundancy, and stacked with other BLC 6000 assemblies for full system capabilities.
The 6214 blade is a complete DSLAM solution including the splitter that allows the POTS lines to be directly attached to the blade and the composite POTS plus ADSL2Plus to be delivered to the subscribers.
