Cisco Enhances LightStream 2020 ATM Switch with Industry-Leading LAN/WAN Services.


BILLERICA, Mass.--(BUSINESS WIRE)--June 19, 1995--Cisco Systems today announced advanced features for its LightStream 2020 enterprise ATM switch that boost performance, integration, connectivity and manageability for applications such as videoconferencing and multimedia.

The new feature set includes ATM, FDDI (Fiber Distributed Data Interface) Often pronounced "fiddy," it was a LAN and MAN access method that had its heyday in the mid-1990s. FDDI was an ANSI standard token passing network that transmitted 100 Mbps over optical fiber up to 10 kilometers.  and Ethernet services for LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used.  and WAN environments that enhance the LightStream 2020's position as the industry's most advanced multi-service enterprise ATM switch. Key new software and hardware features, available in August as part of the Cisco Internetwork Operating System (Cisco IOS) for ATM are: T1/E1 circuit emulation, application-specific quality of service for integrated LAN ports, high-performance multicast service, a frame relay network node interface (networking) Network Node Interface - (NNI) The ATM Forum's specification for connections between network nodes. NNI makes network routing possible. It typically refers to backbone trunk connections between ATM switching equipment.

, a topology map and a new eight-port T3/E3 interface card.

"While many users view ATM as the foundation for the enterprise networks of the future, they need to improve and preserve their investments in existing network infrastructures," said Joe Uniejewski, director of marketing for enterprise ATM products. "As an evolutionary step toward end-to-end ATM, many are adopting switched internetworking solutions that combine an ATM backbone with such traditional interfaces as Ethernet and FDDI. The Cisco LightStream 2020, with the new enhancements, provides an ATM-based multiservice solution that will migrate easily to full ATM at the user's pace."

"Our internetwork topology is a veritable alphabet soup," said Jim Nemchak, director of network services at the University of Colorado University of Colorado may refer to:
  • University of Colorado at Boulder (flagship campus)
  • University of Colorado at Colorado Springs
  • University of Colorado at Denver and Health Sciences Center
  • University of Colorado system
 Health Science Center. "We wanted an ATM solution that could support multiple LAN protocols, interact with our existing interface technology, and deliver wire-speed throughput. The Cisco LightStream 2020, with its new functionality, meets all our needs."

T1/E1 Circuit Emulation, Application-Specific QoS

T1/E1 circuit emulation, based on the ATM Forum AAL (ATM Adaption Layer) The part of the ATM protocol that breaks up application packets into 48-byte payloads which become ATM cells when the 5-byte headers are attached. The AAL resides between the higher layer transport protocols and the ATM layer. 1 specification, lets users interconnect PBX (Private Branch eXchange) An inhouse telephone switching system that interconnects telephone extensions to each other as well as to the outside telephone network (PSTN). , bandwidth managers and video conferencing equipment across a LightStream 2020 network using constant bit rate services. The LightStream 2020 supports up to eight T1/E1 ports per module for a maximum fanout of 72 ports -- the industry's highest port density for an enterprise ATM switch.

Application Specific Quality of Service (AS/QoS), an industry first, extends ATM QoS to FDDI and Ethernet traffic, by application, at both layers 2 and 3. This allows ATM bandwidth and quality of service to be allocated to LAN-based "power users" of multimedia, desktop video, client/server and other applications.

High Performance Multicast, Frame Relay, Topology Map

High Performance Multicast Service (HPMS HPMS Highway Performance Monitoring System
HPMS Harper Park Middle School
HPMS Hierarchical Process Modeling System
HPMS High Performance Mass Spectrometers
HPMS High Performance Monitoring System
HPMS Home Pain Management Systems, Inc.
) allows the LightStream 2020 to forward multicast packets at full line rate within the ATM infrastructure. In conjunction with AS/QoS, HPMS lets the user allocate bandwidth and priority of service by application to multicast groups. The LightStream 2020's HPMS utilizes point-to-multipoint ATM connections to deliver high performance multicast service.

Frame Relay Network Node Interface allows the LightStream 2020 to connect to other vendors' frame relay switches, passing frames through a high-speed ATM infrastructure.

In addition, a new topology map feature allows the user to view network status -- color-coded by traffic type or priority -- and changes in physical topology. A pop-up menu provides detailed information on all LightStream 2020s in the network.

New T3/E3 Hardware Interface Module

An eight-port T3/E3 interface card boosts performance to line speed for up to 72 T3/E3 ports on a 12-slot LightStream 2020 chassis, providing the highest T3/E3 port density of any available switch.

The new release of the Cisco LightStream 2020 will be available in August and will range in price from $21,900 - $200,000.
