Passport 7400/15000 Series for Enterprises—Multiservice WAN Switches

Many enterprises today have multipledisparate networks operated and man-aged separately. A typical corporationmay include a private voice networkconsisting of PBXs and key systems networked together over private lines, an outsourced ISDN video conferenc-ing solution from a local serviceprovider, and one or more data net-works supporting a wide range ofdiverse applications. The implementa-tion of a highly available multiserviceWAN platform provides for the inte-gration of voice and data networks and brings video conferencing in-house—all at reduced costs.

Product Brief

Enterprises 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 likely considering how to streamline network

operations and management by consolidating your voice, video, and

data traffic.

When implementing a consolidated Wide Area Network (WAN) solution,

you cannot afford to compromise mission-critical services’ availability.

Because corporate voice services are the most demanding test of a consoli-

dated network, it is important to 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 support availability and reliability, while maintaining traffic priority.

To meet this challenge, Nortel Networks offers its market-leading Passport

WAN Switches to deliver the services and solutions you require.

tions through public ATM or framerelay network services where band-width, cost, and improved businessreach are required.

Superior voice quality Passport 7400’s feature-rich MVPvoice services are a result of years oftelephony experience. It supports themost popular voice signaling protocolssuch as ETSI Q.SIG, NIS, CAS, EuroISDN, and MCDN. With MCDN onPassport, customers can interconnectthe huge installed base of Meridian 1networks over a converged ATM basewhile preserving the rich set of value-added telephony features. To ensuretop-quality voice, Nortel Networkssupports features such as tandem pass-through, which eliminates unnecessarydecompression and compression cyclesfor tandemed PBXs, resulting in lessdelay and improved voice quality.

Nortel Networks voice capabilities notonly offer superior voice quality, theyalso offer the most efficient use ofbandwidth. The Passport 7400 enter-prise voice solution supports voiceusing the ATM adaptation Layer 5(AAL5). With AAL5, unused trunkbandwidth can be dynamically allocat-ed to support data traffic, giving yournetwork greater bandwidth efficienciesthan a reserved bandwidth scheme.

For further bandwidth savings,Passport supports high quality voicecompression—from G.726 - ADPCM(32/24 kbps) all the way down toG.729 - CS-ACELP (8 kbps)—withthe ability to dynamically compress to

As an integral part of that strategy,Nortel Networks offers the Passport7400 and Passport 15000 series ofMultiservice WAN Switches for corporate, government, and industryclients looking for a high-availability,multiservice WAN platform.

What makes Passport in the enterprise exceptional? The Passport products are designed tooffer reduced total cost of ownership,superior voice quality, business-grade IPservices, high-network availability, “rocksolid” reliability, and end-to-end QoSfor companies wanting to integrate multiple networks—making it an idealsolution for the challenges in today’senterprise networking environment.(Figure 1)

Reduced total cost of ownership Nortel Networks Passport MultiserviceWAN solution enables enterprises toconsolidate voice, video, and data net-works into a single consolidated WANsupporting a wide range of access andtrunking options—providing signifi-cant infrastructure and operational costsavings. With Passport, enterprises havethe choice of consolidating multipletraffic types over private lines, publicATM, frame relay, and even Multi-protocol Label Switching (MPLS).

Enterprises still relying on TimeDivision Multiplexing (TDM) net-works can realize significant cost savings as well as take advantage ofPassport’s dynamic bandwidth capa-bilities and QoS. Passport seamlesslyincorporates reliable, private connec-

higher compression levels upon detect-ing congestion in the network. Otherfeatures that contribute to Passportbandwidth efficiencies include speechactivity detection (SAD), which pre-vents silence from being packetized and sent across the WAN, and fax/modem detection, which reduces bandwidth by suppressing idle periodsbetween data bursts.

Nortel Networks award-winning voicenetworking capability allows Passportto interpret public branch exchange(PBX) signaling protocols and routeindividual calls directly, instead ofthrough a tandem PBX. The best pathbetween the ingress and the egress end-points is selected on a call-by-call basisusing ATM SVCs. When a voice net-working PBX call clears, the SVC istorn 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 Passport 7400 MVP hard-ware base is comprehensive, designedto eliminate the need for externalequipment such as echo cancellers and gateway converters.

Business-grade IP servicesPassport also supports secure, scalable,and reliable IP-Virtual Private Networks(VPNs) with an architecture that offersa cost-effective way of creating multiple,segregated IP-VPNs in a shared envi-ronment. Using either virtual routers(RFC2764) or MPLS (RFC2547), each Passport supports site-to-site IPtransport, QoS, and dynamic IP routing protocols.

Passport IP-VPNs can be used for separating traffic based on companydepartments or network application.If an enterprise operates a Passport network today, IP-VPN capability isachievable through a software upgrade,requiring no change to the networkinfrastructure. There is no need forflash cutovers or Customer PremisesEquipment (CPE). Economies of scaleare achieved with the ability to sup-port very large numbers of virtualroutes per node using the VPNExtender Card, and non-stop serviceavailability is ensured throughPassport's carrier-grade IP routing and forwarding capabilities.

Passport’s integrated RFC2474 solu-tion provides for classification, mark-ing, and queuing of the IP flows to therequired DiffServ treatment. (Figure 2)IP-VPN SLAs can be established witheach VPN based on Passport’s QoS

attributes such as bandwidth required,acceptable level of packet loss, networktransit delays, and security levels for dif-ferent types of customer traffic. Theseparameters permit customers to detailhow different types of traffic areprocessed based on user, application, ortraffic type. QoS requirements for eachof these traffic types can be mappedonto frame relay, ATM, or MPLS.

Passport IP-VPN services operate inde-pendently of the core network trans-port technology, which can be framerelay, ATM, IP, or MPLS. This flexi-bility enables customers to implementIP-VPNs on existing infrastructuresand then migrate smoothly whendesired or as new technologies areadopted.

As a major advantage, the Passport15000 is architected to support hitlesssoftware upgrades, which ensures userconnections remain active during thesoftware upgrade process—virtuallyeliminating one of the key contributorsto reduced availability.

End-to-end QoS Designed for industry-leading perfor-mance, Passport maximizes the use ofnetwork resources and minimizes theimpact of congestion and failures. Asophisticated traffic management sys-tem—Multiple Priority System(MPS)—is used to ensure that the maxi-mum amount of traffic is transmitted onthe link, while still ensuring that higherpriority traffic gets transmitted first dur-ing congestion situations. It allows opti-mization of resources, dynamically allo-cates bandwidth, reduces traffic conges-tion, and provides the least possible net-work latency to guarantee service levelsfor all traffic types.

Comprehensive networkmanagement Critical to any enterprise network iscomprehensive network management—the ability to remotely manage, monitor,and respond to issues from anywhere inthe network.
