Sourcecom boldly launches the first of a new breed of networking platform -- the BANC 6000 DSLAM-Plus.WESTLAKE VILLAGE, Calif.--(BUSINESS WIRE)--Sept. 9, 1996-- Sourcecom has once again shattered technology barriers by delivering the BANC [French, Bench.] The location where a court customarily or permanently sits. When a court is sitting in banc (or en banc), it means that a meeting or session of all the judges of a court is taking place. 6000 DSLAM-Plus -- the industry's first LAN/WAN-Frame-and-Cell-switching-and-routing access product that enables telcos to construct the next-generation, mammoth-scale XDSL-based public broadband access See broadband and wireless broadband. networks prescribed by Sourcecom's standards-setting BroadWave blueprint. (See BroadWave news release.) Christopher J. Rust, Sourcecom's Broadband product manager, stated: "We have custom-designed the BANC 6000 to support the highly specialized requirements of broadband subscribers and providers. The BANC 6000 sets a new industry benchmark in performance, cost and functionality. It switches and routes frames and cells at multi-megabit per second wire speeds, and at a drastic price/performance advantage over existing single-function platforms." Enterprise and Campus Solutions Don't Apply No campus nor enterprise platform -- router, Ethernet switch A device that connects clients and servers to each other in an Ethernet network. See switched Ethernet. , WAN switch, ATM switch/multiplexer or filtering bridge -- has the right functionality, cost points, performance or form factors to support the specialized needs of public Broadband Access Networks. While others are trying to retrofit their campus and enterprise devices to meet those needs, Sourcecom has "distilled" these devices down to their basic elements; extracted the pertinent elements of each; added a suite of service-specific networking functions -- including the InnerWare Broadband Access Networking Services (BANS) (see BroadWave news release) -- and combined it all in the BANC 6000. From Trials to Deployment Within the Access Provider Wire Center, such as a Telco Central Office, the BANC 6000 serves as the aggregator of XDSL connected subscribers to the ATM or Frame Relay A high-speed packet switching protocol used in wide area networks (WANs). Providing a granular service of up to DS3 speed (45 Mbps), it has become popular for LAN to LAN connections across remote distances, and services are offered by most major carriers. backbone. Through the BANC 6000, subscribers have access to multi-megabit services like work-at-home Transparent LAN Services A service from a carrier that links remote Ethernets together. It is called "transparent" because the connected Ethernets are viewed as one Ethernet by the customer, regardless of the technology employed by the carrier in between. (TLS (1) (Transport Layer Security) A security protocol from the IETF that is based on the Secure Sockets Layer (SSL) 3.0 protocol developed by Netscape. TLS uses digital certificates to authenticate the user as well as authenticate the network (in a wireless ), on-line services such as America Online See AOL. , and Internet Access See how to access the Internet. . Building upon the trial models (see BroadWave news release), the BANC 6000 simultaneously replaces Ethernet termination in the XDSL modems, the Ethernet switch and the enterprise router. For cell-based models, the BANC 6000 replaces the cell termination in the XDSL modems as well as the associated ATM switch or multiplexer. All of these functions are soft-configurable in a single BANC 6000. Distributed BANC Group: Over 1,000 XDSL Lines and 65,000 Subscribers The BANC 6000 DSLAM (DSL Access Multiplexor) A central office (CO) device for ADSL service that intermixes voice traffic and DSL traffic onto a customer's DSL line. It also separates incoming phone and data signals and directs them onto the appropriate carrier's network. See DSL. Plus offers a unique scaleability method that matches providers' provisions of 1,000 subscriber sites to an OC3C OC3C Optical Carrier level 3 - Concatenated (single channel for 155.52 Mbps leased line) ATM link. In a distributed BANC Group, up to 32 BANC 6000s can be cascaded onto a 33rd BANC 6000 in a star topology See star network. offering connectivity up to 1,024 subscriber sites. The 33rd BANC can be replicated for maximum network resiliency. This configuration limits the impact of any single BANC 6000 failure to 32 subscriber sites. Alternatively, the BANC units can be aggregated using an off-the-shelf ATM or Frame Relay switch. A BANC group of 33 BANCs is capable of supporting up to 1,024 subscriber sites or as many as 65,536 uniquely addressable Reachable. When something is addressable, it can be identified and manipulated independently of its surroundings. For example, screen pixels and RAM memory are addressable. Each of the screen's picture elements can be individually turned on and off, and each of the memory's bytes can be PCs or subscribers. The Future of Silicon Integration Today The BANC 6000 takes full advantage of Distributed InnerWare (see BroadWave news release). The BANC 6000's architecture, fully integrated onto a single board, employs a Gigabit bus and a set of four distributed InnerWare Multi-Layer Switching Elements (MLSE MLSE Maximum Likelihood Sequence Estimation (algorithm) MLSE Maple Leafs Sports Entertainment MLSE Model Law Structural Engineer MLSE Maintenance Loop Signaling Entity MLSE Maximum Likelihood Sequence Estimator ), supporting a total of 32 WAN ports. Each MLSE is a combination of ASICs and highly optimized firmware, and is capable of switching either cells or layer 2 and layer 3 frames at full wire speeds for a group of 8 ports. Each of the 8 MLSE WAN ports supports up to an aggregate of 12 Mbps of bandwidth (upstream plus downstream), allocated through a dynamic, self-detecting procedure that allows the BANC to support all XDSL speeds available today and the foreseeable future. An ATM uplink module supports one OC3-C 155Mbps backbone attachment, while a Frame Relay uplink module supports two, primary and backup, 8Mbps Frame Relay backbone connections. The uplink module allows the provider to provision the correct size uplink for each unique stage of service ramp. The Control Element (CE) resides in an independent processor and provides management, configuration and overall system control. Through BANC's ATM backbone support, providers have the flexibility to connect to both traditional ATM switches as well as Ipsilon-compliant IP switches, without requiring expensive standalone enterprise routers. (See Sourcecom/Ipsilon news release.) Simultaneous Wire Speed Performance on All Ports The BANC 6000 saturates all links at wire-speeds, delivering an aggregate throughput of more than 500,000 packets or cells per second per BANC 6000 or 16 million packets or cells per second per distributed BANC group. Unsurpassed Investment Protection Because the BANC 6000 is built to support cells and frames, providers' investments are protected. With the deployment of subscriber cell-based devices, a BANC 6000 can be soft-configured for cells or frames in groups of eight ports (per MLSE). This allows BANC 6000 based infrastructures to support data applications today and video-on-demand and other cell-based applications tomorrow. Decoupled Transmission Connectivity Each of the 32 ports offer a V.35 connection in increments of four ports per cable. The transmission technology, such as ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line and HDSL See DSL. HDSL - High bit-rate Digital Subscriber Line modems, are attached through the V.35 connections. This decoupling Decoupling The occurrence of returns on asset classes diverging from their normal pattern of correlation. Notes: Take for example stock and corporate bond returns, which normally rise and fall together. allows the variety of XDSL modems and speeds to be supported immediately and allows for optimum evolution of networking and transmission equipment, while protecting investments and maximizing network resiliency. InnerWare BANS Software Suite The BANC 6000 supports InnerWare BANS Phase II for maximum subscriber and provider service flexibility. InnerWare BANS supports both frame- and cell-mode service models, allowing frames or cells to be delivered to a subscriber site. InnerWare BANS also supports dedicated frame-mode virtual circuits ideal for work-at-home service offerings, as well as public Virtual LANs (VLAN See virtual LAN. VLAN - Virtual Local Area Network ) based on shared virtual circuits tailored for online and Internet access services. (See BroadWave news release for additional details on InnerWare BANS.) A New Management Paradigm The BANC 6000 leverages standard SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc. platforms, Java for Web-based management, and the distribution of management proxy agents for cost-sensitive subscriber equipment. An extensive set of MIBs provide the basis for GUI-based applications to manage all aspects of the BANC 6000 and associated subscriber gear.
