converge

Product Brief nterprises today are faced with doing more with less and are challenged to find new and innovative ways to control networking costs. To reduce costs, you are more than Networks likelyE considering how to streamline network operations and management by converging your voice, video, and data traffic. Multiservice Switch When implementing a consolidated (WAN) solution, you cannot 7400/15000 Series afford to compromise mission-critical services’ availability. Because corporate voice services are often the most demanding test of a consolidated network, it is important to for Enterprises choose a solution that offers stringent Quality of Service (QoS) to ensure voice traffic receives the highest priority through the network. Therefore, any changes in networking infrastructure must deliver superior availability and reliability, while maintaining traffic priority. To meet this challenge, Nortel Networks offers its market-leading Multiservice Switches to deliver the services and solutions you require. Many enterprises today have multiple disparate networks operated and managed separately. A typical corporation may include a private voice network consisting of PBXs and key systems networked together over private lines, an outsourced ISDN video conferencing solution from a local service provider, and one or more data networks supporting a wide range of diverse applications. The imple- mentation of a Multiservice Switch (MSS) WAN platform provides for the convergence of voice and data networks and brings video conferencing in-house—all at reduced costs. As an integral part of that strategy, Nortel Networks offers the Multiservice Switch 7400 and Multiservice Switch 15000 series of Multiservice WAN Switches for enterprises in both private and public sectors looking for a reliable, cost-effective multiservice WAN platform.

What makes Multiservice Switches in the enterprise exceptional? The Multiservice Switch products are designed to offer reduced total cost of ownership, superior voice quality, business-grade IP services, high-network availability, “rock solid” reliability, and end-to- Multiservice Switch 7460 end QoS for companies wanting to converge multiple networks—making it an ideal solution for the challenges in today’s enterprise networking environment.

Reduced total cost of ownership Nortel Networks Multiservice Switch solution enables enterprises to consolidate voice, video, and data networks into a single consolidated WAN supporting a wide range of access and trunking options—providing significant infrastructure and operational cost savings. Enterprises still relying on Time Division Multiplexing (TDM) networks can reduce up to 79 percent of leased line costs using Multiservice Switch 7400 voice technology.† Using industry- leading multiservice access technology such as the new single-slot, 32-port DS-1/E1 interface supporting IP, ATM, frame relay, and circuit emulation, enterprises can further reduce the customer premises equipment required for their converged network.

Superior voice quality Multiservice Switch 7400’s feature-rich MVP (Multipurpose Voice Processor) voice services are a result of years of telephony experience. It supports the most popular voice signaling protocols such as ETSI Q.SIG, NIS, CAS, Euro ISDN, and MCDN. With MCDN on Multiservice Switch 7400, customers can interconnect the large installed base of Meridian 1* networks over a converged ATM base while preserving the rich set of value-added telephony features. To ensure top-quality voice, Nortel Networks supports features such as tandem passthrough, which eliminates unnecessary decompression and compression cycles for tandemed PBXs, resulting in less delay and improved voice quality.

Actual results may vary if operating factors (for example, deployment scenarios, actual growth rates, and competition) differ from the assumptions made.

2 Nortel Networks voice capabilities not only offer superior voice quality, they also offer the most efficient use of bandwidth. The Multiservice Switch 7400 enterprise voice solution supports voice using the ATM adaptation Layer 5 (AAL5). With AAL5, unused trunk bandwidth can be dynami- cally allocated to support data traffic, giving your network greater bandwidth efficiencies than a reserved bandwidth scheme. For further bandwidth savings, Multiservice Switch 7400 supports high-quality voice compression— from G.726 - ADPCM (32/24 kbps) all the way down to G.729 - CS-ACELP (8 kbps)—with the ability to dynamically compress to higher compression levels upon detecting congestion in the network. Other features that contribute to MSS bandwidth efficiencies include speech activity detection (SAD), which prevents silence from being packetized and sent across the WAN, and fax/ modem detection, which reduces bandwidth by suppressing idle periods between data bursts. Nortel Networks award-winning voice networking capability allows MSS 7400 to interpret private branch exchange (PBX) signaling protocols and route individual calls directly, instead of through a tandem PBX. The best path between the ingress and the egress endpoints is selected on a call-by-call basis using ATM SVCs. When a voice networking PBX call clears, the SVC is torn down, freeing up bandwidth for subsequent calls. This eliminates tandem PBX equipment and can greatly simplify the network topology, providing operational cost savings. Finally, the MSS 7400 MVP-e hardware base is comprehensive, designed to eliminate the need for external equipment such as echo cancellers and gateway converters. All of these above mentioned features are the reason why MSS 7400 is widely deployed by customers relying on superior voice quality for their core business. These include customers in healthcare, finance, education, police, military, transportation, and contact center industries. Not only do these customers save money on facility costs but they also are able to deliver mission-critical applications such as crime prevention, air traffic control, and railway signaling.

Business-grade IP services Multiservice Switch also supports secure, scalable, and reliable IP-Virtual Private Networks (VPNs) with an architecture that offers a cost-effective way of creating multiple, segregated IP-VPNs in a shared environment. Using either virtual routers (RFC 2764) or MPLS (RFC 2547), each Multiservice Switch supports site-to-site IP transport, QoS, and a powerful suite of dynamic IP routing protocols. Multiservice Switch IP-VPNs can be used for separating traffic based on company departments, government entities, or network application. If an enterprise operates a Multiservice Switch network today, IP-VPN capability is achievable through a software upgrade, requiring no change to the network infrastructure. There is no need for flash cutovers on Customer Premises Equipment (CPE). Economies of scale are achieved with the ability to support very large numbers of virtual routes per node using the VPN Extender Card, and non-stop service availability is ensured through Multiservice Switch's carrier-grade IP routing and forwarding capabilities.

3 MSS IP-VPN services operate independently of the core network transport technology, which can be frame relay, ATM, IP, or MPLS. This flexibility enables customers to implement IP-VPNs on existing infrastructures and then migrate smoothly when desired or as new technologies are adopted.

Maximum network availability Responsible for the MSS track record of very high network and service availability are intelligent, self-healing, and self-learning networking systems. Multiservice Switch networking services have been optimized for large enterprise environments, delivering carrier-grade availability. Robust traffic engineering capabilities ensure the network is capable of handling unpredictable events, such as the With Multiservice Switch WAN, loss of a port or link, or sudden surges in traffic volume. Changes in trunking and topology configu- rations can be done without affecting the existing applications. Nortel Networks offers you the Multiservice Switch provides networking systems optimized for both circuit-based traffic and industry's most comprehensive connectionless packet-based traffic across a common trunk infrastructure. Multiservice Switch also aligns to the latest development in standards, such as PNNI and LDP-DU, complete with exten- suite of reliability features, sions for added resiliency. including redundant equipment With Multiservice Switch WAN, Nortel Networks offers you the industry's most comprehensive protection, quick and accurate suite of reliability features, including redundant equipment protection, quick and accurate fault detection, robust networking features, and in-service software upgrades. fault detection, robust networking features, and in-service software “Rock-solid” reliability Multiservice Switch offers high node availability through fully redundant, “hot-swappable” common upgrades. equipment. In addition, a wide selection of optional line and equipment protection redundancy schemes are available, including 1+1 SONET APS/SDH MSP and 1:1 or 1:N redundancy for elec- trical function processors. As a major advantage, the MSS 15000 is architected to support hitless software upgrades, which ensures user connections remain active during the software upgrade process—virtually eliminating one of the main contributors to reduced availability.

End-to-end QoS Designed for industry-leading performance, Multiservice Switch maximizes the use of network resources and minimizes the impact of congestion and failures. A sophisticated traffic management system is used to ensure that the maximum amount of traffic is transmitted on the link, while still ensuring that higher priority traffic gets transmitted first during congestion situations. It allows opti- mization of resources, dynamically allocates bandwidth, reduces traffic congestion, and provides the least possible network latency to guarantee service levels for all traffic types.

Comprehensive network management Critical to any enterprise network is comprehensive network management—the ability to remotely manage, monitor, and respond to issues from anywhere in the network. Built around the FCAPS model, Multiservice Data Manager (MDM) is an open, flexible network management system that provides comprehensive fault management, simplified end-to-end provisioning, and detailed config- uration management for high-quality customer care. MDM also provides the facilities required to easily integrate or expand MSS and MDM into the network and operating environment and efficiently run your operations. With Multiservice Data Manager, enterprises view and manage each MSS node as one of many integrated elements within the network, employ a consistent network view with alarm notification and display systems, activate a suite of applications for functions such as configuration management (provisioning, software distribution, software backup, and restore), fault management, accounting management, statistics management, security management, and synchronization.
