(communications) Asynchronous Transfer Mode - (ATM, or "fast packet") A method for the dynamic allocation of bandwidth using a fixed-size packet (called a cell). See also ATM Forum, Wideband ATM. ATM acronyms. Indiana acronyms. (ATM) layer solution for broadband multiservice network equipment. PMC-Sierra's PM7325 S/UNI-ATLAS-3200 (ATM LAyer Solution) offers broadband service providers the ability to police, monitor and manage network traffic across multiservice core, edge, access and Metro-DWDM equipment. Rapid 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. and third-generation (3G) wireless base station deployment in the access network is driving demand for higher speed ATM aggregation at the edge and core of the data network (see Figure 1). Leveraging embedded DRAM technology, the S/UNI-ATLAS-3200 offers 30% less systems power and 32% less system board space than alternative solutions. With its industry standard POS-PHY Level 3 interface, PMC-Sierra's new S/UNI-ATLAS-3200 enables 2.5Gbit/s wire speed ATM traffic aggregation, more efficient network equipment architectures, lower overall system cost and faster time-to-market. Industry Standard Traffic Policing, Fault and Performance Management Functions Guarantee Quality of Service 2.5 G/bits wire speed address resolution, traffic policing, fault and performance management and statistics gathering features in the S/UNI-ATLAS-3200 empower equipment service providers to offer advanced traffic engineering and real-time network management required for quality of service. The S/UNI-ATLAS-3200's ITU-T See ITU. ITU-T - International Telecommunications Union I.610 compliant Operation and Maintenance (OAM (Operations Administration Maintenance) Refers to managing and maintaining a network or network device. The P in "OAM&P" adds "provisioning" to the list, which is a telephone company term for setting up a service. ) features allow customers to monitor network service availability and performance. On-chip fault management features allow network operators to detect and isolate network faults on any of the 64K virtual connections (VCs) allowing problems to be identified and corrected without noticeable network service interruptions. The traffic policing functions of the S/UNI-ATLAS-3200 are ITU-T I.371 and TM4.1 compliant, enabling service providers and network operators to ensure that service-level agreements are honored between user and carrier as well as between two carriers. The S/UNI-ATLAS-3200 also contains extensive cell and frame counters that collect and monitor traffic statistics on a per connection basis to perform billing functions that are essential components of a contractual subscription service plan. Embedded DRAM Vastly Simplifies System Design and Improves Power and Board Density The new S/UNI-ATLAS-3200 is the networking industry's only ATM Layer device to feature 64-Mbit of embedded DRAM. At 4 Watts typical, its embedded DRAM layout offers nearly one-third (30%) power consumption and one-third (32%) board space savings when compared to alternative configurations implementing SRAM See static RAM. SRAM - static random-access memory externally. This embedded DRAM technology significantly simplifies system design by reducing the amount of external RAM procurement and signal routing required. Additionally, a patented high-performance and look-up binary search algorithm A binary search algorithm (or binary chop) is a technique for finding a particular value in a sorted list. It makes progressively better guesses, and closes in on the sought value by selecting the median element in a list, comparing its value to the target value, and resolves an unrestricted range of virtual path identifier/virtual channel identifier (VPI/VCI VPI/VCI Virtual Path Identifier/Virtual Channel Identifier (used in Asynchronous Transfer Mode) ) addresses at one-fourth the cost of external content 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 (CAM) memory designs. Complete Port Card Architectural Solutions from T1 to OC-48 The S/UNI-ATLAS-3200 builds on PMC-Sierra's complete portfolio of physical layer, protocol processing, traffic management and switch fabric devices ranging from T1 to OC-48 line rates. The S/UNI-ATLAS-3200, which seamlessly integrates with PMC-Sierra's CHESS(TM) chip set, enables the processing of ATM traffic for next generation multiservice switches. "The S/UNI-ATLAS-3200 follows our earlier RCMP-800 (Routing Control, Monitoring, Policing) and ATLAS-800 product generations," said Steve Perna, vice president and general manager PMC-Sierra's Optical Networking Communications between computers, telephones and other electronic devices using light. An optical network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain. See optical fiber. Division. "The seamless integration An addition of a new application, routine or device that works smoothly with the existing system. It implies that the new feature or program can be installed and used without problems. Contrast with "transparent," which implies that there is no discernible change after installation. between S/UNI-ATLAS and our entire OC-48 physical layer, traffic management and switch fabric devices form a complete end-to-end system architecture for the exploding metro-DWDM multiservice edge and core switching markets. Our clear roadmap beyond OC-48 ensures continued system equipment upgrade with PMC-Sierra's standards-compliant, off-the-shelf solutions." Unique Packet Bypass Mode Allows Single IP/MPLS/ATM Port Card Design The S/UNI-ATLAS-3200 device features line and system side interfaces that are POS-PHY Level 3 (PL3) and UTOPIA Level 3 (UL3) standards compliant for simultaneous packet and cell transfer, and cell-only transfer respectively. The device contains a unique packet bypass mode which allows cell processing and simultaneous packet bypass to an external Internet Protocol/MultiProtocol Label Switching (networking) label switching - A routing technique that uses information from existing IP routing protocols to identify IP datagrams with labels and forwards them to a modified switch or router, which then uses the labels to switch the datagrams through the network. (IP/MPLS IP/MPLS Internet Protocol/Multi-Protocol Label Switching ) engine such as a network processor or an IP classification engine. True multiservice processing can be engineered on a single line card (see Figure 2). In systems configured with an MPLS (1) (MultiProtocol Lambda Switching) The earlier name for GMPLS. See GMPLS.
