Passport 7400/15000 Series for EnterprisesMultiservice 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-houseall 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 7400s 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
voicecompressionfrom 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 networksmaking it an
idealsolution for the challenges in todaysenterprise networking
environment.(Figure 1)

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 ofPassports dynamic bandwidth capa-bilities and QoS.

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.
Passports 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

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.
Maximum network availability Responsible for Passports track
recordof very high network and service availability are
intelligent, self-healing, and self-learning networking
systems.Passport networking services havebeen optimized for large
enterpriseenvironments, delivering carrier-gradeavailability.
