-------------------------------------------------------------------- --------------[ D4RKCYDE Present (1999) ]--------------- --------------[ AT&T 5ESS-2OOO Switching Technology ]--------------- -------------------------------------------------------------------- The 5ESS Switch is a most flexible digital exchange for use in the global switching network. Digital switches replaced earlier electromechanical and analog switching systems. The 5ESS equipment switches ISDN voice and data, local voice calls, long distance calls, Internet access, wireless PCS, Advanced Intelligent Network services, interactive video and multimedia services...moving any media on the public switched network. This means the 5ESS Switch provides the system, services and software to transform current networks into multi-functional networks that meet the needs of todays home, business and community. By 1992, the next generation 2000 Switch was created at Bell Laboratories and added to networks worldwide. A digital switch is a single system with multiple applications such as local, toll, operator services. The switch architecture is a modular, distributed architecture with an administrative module, a communications module, and a varying number of switching modules that provide the major processing power in the total communication system. This switch design will allow network providers to offer their customers voice, computer, fax, data, and visual services. FCC (Federal Communication Commission) required quality monitoring process has shown the 5ESS Switch is highly reliable, in fact the 5ESS-2000 switch is four times more reliable than its nearest competitor. Today the 5ESS switch is considered the workhorse of the public telecommunications network in the United States with its lower life cycle costs and its proven record of reliability. Modular Design Advantage ************************ An advantage, when deploying the 5ESS Switch, continues to be its modular design. This modularity allows for ease of implementing ongoing enhancements and allows service providers the ability to change their communication network quickly. The value of the current 5ESS Switch modular architecture and the ease with which is adapts to new technologies has been repeatedly demonstrated. Administrations can deploy new 5ESS Switches in their network, only to find their business requires additional hardware modules and the associated software releases. The new hardware can easily be added to the network's standard growth and modernization plans. The result is an easy, effective, and economical upgrade to a 5ESS-2000 Switch without service disruption. Telephone administrations are often concerned with: Increasing busy hour call completion capacity Minimizing floor space requirements Enabling growth in small increments Integrating multiple applications in one exchange Reducing power consumption and operational costs The 5ESS-2000 Switch architecture and software addresses each of these concerns. Economical access to advanced services via the 5ESS-2000 Switch can be provided to all subscribers no matter where they are located; in metropolitan, suburban or rural areas. A Distributed Architecture ************************** The 5ESS-2000 Switch also features a distributed architecture that employs modular components in all systems and subsystems. This readily accommodates a broad array of growth and configuration options that allow you to easily and economically evolve your network as subscriber demand grows. This flexibility enables you to maintain your competitive edge while saving on sparing, training and documentation. Internet Capacity ***************** Reliability and customer satisfaction are especially important with respect to internet services, since the extensive growth of the Internet has caused an increase in network blockages on existing central offices. However, a new capability, which Lucent refers to as Project Renaissance, helps service providers avoid this problem in a least costly fashion. Today the 5ESS-2000 Switch is the first switch to handle both wireline and wireless traffic. Project Renaissance will modernize and consolidate central offices and networks by using the SM2000 with Digital Network Unit -- SONET-- and the Access Interface Unit to provide increased trunk and line capacity for the service providers network. Project Renaissance also reuses some existing central office equipment. This increased capacity affords opportunities not only for a lower cost structure and simplified network operations, but also a better grade of service with less probability of internet and voice calls being blocked as a result of high internet hold times. Access Interface Unit (AIU) - A new cost-effective non-blocking line unit for the 5ESS Switch that was generally available in 1996. This line unit initially supports enhanced performance and reduced operational costs for analog connections, but will also support ISDN and ADSL in the future. ISDN PRI Expansion - The 5ESS Switch SM-2000 was expanded to handle more PRI terminations in 1996. This capability will lower service provider operational and first-time costs. Provisioning Solutions - The Switch Element Manager Operations Systems will shadow a switch's translation/feature database, making it easier and faster to provision ISDN lines without placing strain on the embedded switch call processors. In early 1997, additional Applications Software will be made available to further enhance the ISDN provisioning process. Provisioning audit services are available to pinpoint trouble spots. Small Exchanges and Remote Capabilities *************************************** Remote line units can support basic and supplementary services and ISDN capabilities. Remote switching systems provide all the duplex switch services of the host exchange and can sustain complete stand alone functionality if remote-to-host facilities are out of service. Small autonomous exchanges, like CDX and VCDX, are configured to support exchange sites where deployment of remotes may be unsuitable. In addition to typical host exchange configurations, the 5ESS Switch offers full service remote switch solutions and interchangeable models to configure the smallest to the largest exchange sites. This simplifies training, documentation, and spare parts while increasing flexibility and services. No longer must network providers procure differing systems for small sites versus large metropolitan exchanges. Over the past seven years the switch has increased busy hour call capacity more than fivefold. The architecture lets the switch add processing power as needed to add extra call capacity. A network service provider need buy only as much capacity as needed to start, then expand later to meet business demands or to bring more features to customers in their market. Thus as business expands, the service provider need only upgrade the modules directly involved, rather than add whole new switches. ---------------{ EOF }-------------| ---------------{ typed up by hybrid }-------------| ---------------{ th0rn@coldmail.com }-------------| D4RKCYDE Communications ---------------{ darkcyde.8m.com }-------------| ---------------{ #darkcyde EfNet }-------------|
