The system includes plug-in blades, chassis, cabinets and management software. It supports standard lifeline POTS phones and DSL modems and integrates into CLASS 5 switching via TR08 or GR 303. And it supports IP IADs, Terminal Adapters or IP phones into IP Softswitches. One or the other, or mix and match simultaneously.
The BLC 6000 incorporates a unique distributed architecture that enables system blades to operate in a 12 slot high capacity chassis or in a standalone 1RU chassis.
6252-02 Blade - ADSL2Plus and POTS with Gigabit Ethernet 
The 6252-02 ADSL2Plus Blade provides 48 ports of ADSL2Plus with Lifeline POTS on the same physical interface to deliver voice, data and video services. Subscriber DSL and POTS ports combine with Gigabit Ethernet transport capabilities to position the 6252-02 Blade as the Triple Play workhorse for the future of the access network.
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 6252-02 provides 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 digital video headends in the switch centers and the core network.
The ADSL/POTS ports include an internal soft splitter that requires no additional external hardware. The POTS traffic from all ports is converted to VoIP with MGCP signaling. The voice, data and video traffic are differentiated and transported over the feeder network following the provisioned QoS parameters. At the central office, the voice traffic can be handed directly to a Next Gen softswitch platform, or a BLC 6000 COT can provide standard TR-08/GR-303 connections to a Class 5 switch.
The Gigabit Ethernet capacity of the 6252-02 provides the very high bandwidth required for video services. Network bandwidth must support hundreds of broadcast channels while sustaining the expected growth of Video On Demand. Even a moderate VOD service subscription rate can consume multiple OC-3s during peak viewing time. Each 6252-02 Blade includes 4 Gigabit Ethernet optical fiber ports. A single port can be used to support initial requirements, and additional GigE ports can be brought on-line as the VOD service grows.
The core IP technology of the BLC 6000 includes Multicast IGMP in the 6252-02 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. This capability preserves feeder bandwidth for VOD and data services, and it eliminates the need for deployment of separate IP processing or routers.
Another advantage of the 6252-02 is streamlined network operation with digital video headends. The video streams are MPEG encoded signals in IP packets. The BLC 6000 system creates a native IP delivery network that rips out the complexity of ATM transport. BLC 6000 eliminates the overhead of transporting large video IP packets chopped into ATM cells. The BLC 6000 IP service delivery model includes edge aggregation, which eliminates the virtual circuit provisioning of the ATM model.
The Gigabit Ethernet core of the 6252-02 is a high performance, wire speed Ethernet switch with 10 ports that can be used for optical (4) or copper (6) connections. The Ethernet ports may be used in any configuration or combination for network transport, for blade interconnection or even for Ethernet service delivery.
The 6252-02 Blade can be deployed standalone as the BLC 6252-02 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 6252 Assembly can be stacked with additional units to add capacity and hardware redundancy, and can be stacked with other BLC 6000 Assemblies for full system capabilities.

The BLC 6000 Series FTTP capabilities represent fully integrated advancements of the BLC 6000 Broadband Loop Carrier. The 6312 Optical Line Termination Blade can be deployed in the same network and nodes with all of the other BLC 6000 system capabilities such as ADSL2Plus and Lifeline POTS. The 6312 creates an active optical FTTP network delivering several advantages over the various PON solutions that are available. Active technology is simpler than PON, which requires sophisticated algorithms to avoid traffic collisions over the shared feeder. Active networks are simpler to plan and deploy because they have no splitters that drive cost versus take rate trade-offs. Active technologies allow higher bandwidth per subscriber and are more open to equipment from multiple vendors and to future advancements. Active solutions can cost less, particularly when extending an existing access network with fiber already deployed to remote cabinets.
The 6312 Optical Line Termination Blade and BLC 6312 Assembly provide direct active fiber subscriber access distribution and Gigabit Ethernet transport for the BLC 6000 Broadband Loop Carrier system. The 6312 Blade is a high performance Ethernet switch with 22 Gigabit Ethernet ports: 18 optical and 4 optical/copper.
The 6312 supports Gigabit Fiber Subscriber ports, which work with a series of Occam Networks Optical Network Terminals to provide a variety of capacities in Lifeline POTS and high speed Internet traffic and video services. These ports can deliver symmetrical services for business or residential offerings or asymmetrical services by setting rates in each direction. The 6312 optical Gigabit ports can also support Ethernet Protected Switching for all services.
The 6312 Blade can be deployed standalone as the BLC 6312 Assembly, or it can be used in high density deployments with other BLC 6000 Blades in the BLC 6012 high capacity chassis.

The Gigabit fiber link can be set for total bandwidth in each direction as well as for allocating bandwidth for each service VLAN. Each service can be assigned to one of eight priority levels. Transparent LAN services can be provided to corporations, universities and other large customers whose VLAN tags are transported across the BLC network for private Ethernet networking.
Ethernet Transport Flexibility:
The 6312 Blade and BLC 6312 Assembly are designed for a wide range of network applications. The flexibility of Ethernet switching allows any port to be used for any service or transport.

This flexibility makes the 6312 ideal for high capacity feeder transport for all services in the loop network.
The IBIA of the BLC 6000 features distributed processing intelligence and a unique blade interconnection system that allows the flexibility of cost effective configurations in low, medium and high density applications. Four of the Gigabit ports can be switched to copper Gigabit Ethernet ports, which are typically used for protected interconnection with other blades. The copper GigE ports can also be used to connect other collocated, high speed Ethernet devices to the network such as video headends and Internet routers.
6314 Blade - 10 Gig Optical Line Termination
The 6314 expands the speed of the Ethernet Protected Switching network transport from 1 Gigabit to 10 Gigabits.
