The CN 5140 features ahigh-capacity switching fabric with 24Gigabit Ethernet (GbE) ports in a compact2 RU form factor that allows front accessto power and all system interfaces. TheCN 5140 has an extended temperaturerange (-40 to +65C) and a robust physicaldesign that supports deployment in awide variety of unconditionedenvironments, including GR-487 and ETSI-compliant outdoor cabinets. Because theswitch provides both SFP and RJ-45connectors for each of its 24 GbEinterface ports, the CN 5140 can supportservice aggregation, transport, anddemarcation applications in a wide varietyof network topologies, including fiber andmicrowave rings, point-to-point fiber,microwave mesh, fiber or copper tosubscriber, MTU/ MDU/FTTx, and more.

The CN 5140 is based on Ciena’s fieldproven True Carrier Ethernet™technology, deployed by dozens ofnetwork operators in tens of thousands ofbusinesses, homes, and mobile basestation cell sites. The switch combines thelow cost and high capacity of Ethernetwith the reliability, management, andservice quality usually associated withSONET/SDH networking systems. The CN 5140 software architecture is based onthe common service-aware operatingsystem used in all Ciena service deliveryand aggregation switches to provideoperational efficiency and consistentsystem and service attributes.

The core of the CN 5140 is a high-performance switching platform thatincorporates the latest innovations in

Ethernet switching technology, controlplane protocols, and encapsulationtechniques, and Carrier EthernetOperations, Administration, andMaintenance (OAM) mechanisms. Theresult of these combined capabilities is astate-of-the-art design that enables theCN 5140 to deliver the sophisticatedQuality of Service (QoS) capabilities,superior Virtual LAN (VLAN) and virtualswitching functions, and robustmanagement and performancemonitoring features required to supportcarrier-grade Layer 2 Virtual PrivateNetworks (L2VPNs), mission-critical data,high-speed Internet, and high-quality IPTVand VoIP services.

The advanced design and service-richarchitecture of the CN 5140 enablenetwork operators to deploy reliable andscalable offerings that leverage theinherent high capacity and cost-effectiveness of Ethernet technology togenerate maximum revenue. Ethernetbusiness, transport, wireless backhaul, andresidential services can be rolled outquickly and reliably, with low cost persubscriber and optimum utilization ofnetwork resources.

The CN 5140includes 24 GbEports thatsupport100/1000 Mb/soperation overfiber via SFPconnectors, and 10/100/1000 Mb/soperation overcopper via RJ-45connectors.

Carrier-ClassQoS

The CN 5140 implements carrier-class, MEF-14-compliantQoS mechanisms that enable the delivery of a wide range of traffic types and rates over a single access infrastructurewithout interference or degradation.

These capabilities include:

> Rich classification of traffic flows based on Layer1through Layer 4 parameters, including physical port,MAC address, VLAN tag, and IP or Layer 4 port address

> Flexible priority resolution for Class of Service mappingbased on priority settings contained in IP packet headersand VLAN, MPLS, and PBB-TE tags

> Sophisticated ingress metering for CommittedInformation Rate (CIR), Excess Information Rate (EIR),Committed Burst Size (CBS), and Excess Burst Size (EBS)service delivery

> Two-rate Three-Color Marking (trTCM) and Random EarlyDrop (RED) for sophisticated congestion handling

Carrier Ethernet Services, Transport, PBB-TE

The CN 5140 offers a variety of Carrier Ethernet transportoptions, including:

> 802.1q VLANs

> 802.1ad Provider VLANs (Q-in-Q)

> MEF Ethernet connections—including Ethernet VirtualPrivate Line/LAN/Tree services

> 802.1Qay PBB-TE (Provider Backbone Bridging-TrafficEngineering) tunnels with PBB-TE Ethernet virtual circuits

Ciena is an industry leader in the implementation of PBB-TE, which extends and adapts Ethernet to providecarrier-grade transport over Metro and Wide AreaNetworks (MANs and WANs). The CN 5140’s advancedPBB-TE feature set delivers a reliable, resilient, and cost-effective transport solution, ideal for delivering a variety ofnew services to a fast-growing customer base. This featureset includes the PBB-TE tunneling protocol with built-inbackup tunnels, a dual homing tunnel option, tunnel

Based on extensions to current Ethernet standards, PBB-TE-enabled products maintain compatibility withexisting Ethernet deployments, enabling the CN 5140 to deliver a wide range of connectivity services withguaranteed QoS while interoperating seamlessly with an installed base of multi-vendor switching and routingsystems that do not support PBB-TE. Because theadvantages of PBB-TE are available without necessitatingmajor changes to existing network equipment orarchitectures, the CN 5140 offers superior investment protection.

Proven Service-Aware Operating System

The CN 5140 software architecture is based on thecommon service-aware operating system used in all Cienaservice delivery and aggregation switches. This operatingsystem delivers consistent benefits across all Ethernetaccess and aggregation applications, including:

> Rapid implementation of the latest advances in Ethernettechnologies, new services, and standards proposed bythe IEEE, IETF, and MEF

> Interoperability with Ethernet equipment from othervendors

> Improved efficiency and cost savings resulting from acommon deployment and service provisioning model

> Ubiquitous service offerings, permitting rapid rollout ofnew services across the entire network

The CN 5140 software is designed to deliver plug-and-play activation, making new service rollout fast and easy.The switch also supports an advanced automaticactivation feature that can upgrade default settings todeploy operator-specific configurations, reducing newplatform integration time and enabling network operators to extend services to new subscribers rapidly and efficiently.

Carrier-Grade Ethernet OAM

The CN 5140 supports a rich set of OAM features definedin the latest versions of IEEE, ITU, and IETF standards,including:

> IEEE 802.3ah Ethernet in the First Mile (EFM) physicallayer OAM, including link events and remote loopback

> IEEE 802.1ag Connectivity Fault Management (CFM),including MAC Ping/Traceroute and Continuity Check

> ITU Y.1731 performance management

> 802.1AB Link Layer Discovery Protocol (LLDP)

> IETF Two-Way Active Management Protocol (TWAMP)with complete sender and receiver capabilities

These capabilities enable the CN 5140 to monitor thestatus of system and network links; measure theperformance of customer Ethernet services; confirm thatlink and service throughput and quality conform toSLAs;and distribute this management information acrosspoint-to-point, point-to multipoint, and multipoint-to-multipoint connections.

Ethernet Services Manager (ESM)

Ciena’s Ethernet Services Manager (ESM) is agroundbreaking carrier-grade, automated serviceactivation, creation, and management platform formanaging service delivery and aggregation networks,allowing users to:

> Build and deploy large-scale Carrier Ethernet networksquickly and easily
