BLC 6000 Blades

The BLC 6214 is a 48 port ADSL2Plus access multiplexer blade with integrated splitters. The blade takes analog voice input from legacy third-party end office switches or loop carrier equipment and combines the telephone signals with Occam's high performance ADSL2Plus technology on a hybrid analog and digital subscriber line. The end result is a very flexible platform for delivering advanced digital services such as high-speed data and robust televisiona and video services. It is an ideal blade for service providers that want to maximize the value of their traditional telephone delivery network whilt transitioning to a next generation IP-based network infrastructure.

The Gigabit Ethernet ports of the BLC 6214 blade provide integral optical fiber transport for the system. The blade is equipped with ten Gigabit Ethernet ports: four optical and six copper. The Ethernet ports may be used in any configuration or combination for network transport, for blade interconnection or for Ethernet service delivery.

IP Video Optimized

With multiple Gigabit Ethernet transport, the BLC 6214 blade provides sufficient bandwidth to deliver video services today and into the future. It can simultaneously support 512 unique broadcast channels and provides sufficient bandwidth to sustain the expected growth of Video On Demand (VOD), IPTV and other advanced video services.

Like all Occam BLC blades, the BLC 6214 includes IGMP-based multicast optimization to allow 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 eliminates the need for common controls and separate equipment to manage multicast, IP processing and subscriber traffic security.

Service Delivery, Testing and Troubleshooting Tools

The BLC 6214 DSL ports were designed to deliver maximum throughput with the lowest internal electromagnetic noise and port-to-port crosstalk. This ensures the highest train rates and lowest impact from binder loading as take rates increase. The blade supports ADSL2Plus, ATM header compression and loop bonding and supports high impulse noise protection, physical retransmission, seamless rate adaptation (SRA) and frequency “notching” with PSD masks to help prevent any constant or spurious noise on the line that could result in blocking or tiling of the video service. The ADSL interfaces of the Occam BLC 6214 support a range of off-the-shelf ADSL modems including: ADSL G.DMT, ADSL G.DMT with S=1/2, ADSL2 and ADSL2Plus.

Line testing is built into each copper access port. Single ended line testing (SELT) helps service providers properly qualify a customer for a specific level of ADSL service and identify trouble areas in the outside plant that should be addressed before offering robust entertainment services in an area. Dual ended line test (DELT) capabilities of the Occam DSL subsystem allow service providers to proactively conduct quality assurance testing of the physical subscriber line. Dr. DSL, an innovative loop diagnostic software tool, is tightly integrated with Occam’s DSL solutions and provides intuitive, comprehensive DSL performance and benchmark analysis.

Common OS Enhances Blade Operation and Service Management

Like all BLC 6000 blades, the BLC 6214 features OccamOS, a common operating system that spans the entire range of BLC 6000 copper, Gigabit Ethernet and GPON products to provide consistent and uniform system and service attributes. This OS integrates a wide range of Occam copper and optical broadband technological advancements including the company’s patented IP Security Management (IPSM), which allows for dynamic, “hands free” network security.

OccamOS also offers excellent tools to identify and troubleshoot Internet, voice and IPTV delivery problems including a full set of notification events, statistics and service assurance tools that allows for dynamic monitoring of any IPTV stream at any point in the network. And Ethernet Protection Switching (EPS) delivers “carrier grade” network availability, flexible network topologies and use of all network bandwidth through traffic load balancing during normal operation.

Simple Management and Deployment Flexibility

This Occam ADSL2Plus blade can be easily managed through the integrated command line and web interface or through OccamView Element Management System, a robust, carrier-class element management system ( EMS) that manages Occam BLC-based access networks effectively and economically.

The BLC 6214 blade can be deployed standalone, or it can be used in medium- or high-density deployments with other BLC 6000 blades in the BLC 6006 medium capacity chassis or the BLC 6012i/6012 high capacity chassis. A single blade BLC 6214 may be stacked with additional units to add capacity and hardware redundancy, and stacked with other BLC blades for full system capabilities.

Multiple Applications

The BLC 6214 can be used in a variety of applications, including:

• Complete high speed Internet (HSI) IP DSLAM solution
• Low density remote or high capacity CO deployments
• Video optimized access
• Transparent LAN services
• Multiple Gigabit Ethernet optical transport
