A-2140 Carrier Ethernet Edge Switch

Nokia Siemens Networks A-2140 Carrier Ethernet Edge Switch hasbeen developed specifically for delivering MEF-based E-Line, E-LAN and E-Tree services in the most mission critical customer environments as well as in Central Offices, Carrier Point of Presenceand Collocation Cages with stringent environmental requirements. This 1U MEF-certified device is fully NEBS compliant, equipped with two redundant hot-swappable AC or DC power supplies and Dry Contact alarm interface for alarm management.

In addition to Ethernet services and triple-play services, withNokia Siemens Networks’ industry-leading Circuit EmulationService support, the A-2140 can help service providers to migrate TDM-based traffic seamlessly over a high-perform-ance, cost effective Carrier Ethernet network.

With the rapid increase in the need forhigh bandwidth, and the equally im-pressive increase in the performanceof Ethernet within the LAN environ-ment, the demand for metro networkperformance has never been greater.The biggest challenge for service

Features

• Carrier-class features such as compliance with NEBS, redundantpower supplies, and dry contact

• Multi-service enabled, including E-Line,E-LAN, E-Tree, CES, and triple-playservices, on a single device

• Support for Hard QoS such as CIR,EIR and Priority

• Support for 50ms carrier-class protection without using Spanning Tree Protocol

• High performance and very low delayand jitter

• Strong and comprehensive OAM functions such as Ethernet Loopbacksand per-connection SLA measurement

• Compact with just 1U height

providers of all types is to deliver notonly cost-effective and scalable per-formance, but also, and more impor-tantly, a Carrier Ethernet solution thatfacilitates new services, rapid and easyprovisioning and dramatically reducedoperational costs.

A-Series Switches End-to-End Carrier Ethernet Solution

Product OverviewNokia Siemens Networks A-2140complements the A-2000 series pro-duct line by adding redundant powersupplies in a NEBS compliant chassisfor the most mission critical applicationsand for providing Ethernet servicesfrom Carrier Central Offices, PoPs andCollocation Cages. It is a one rack-unithigh, compact Carrier Ethernet Edge

Switch that delivers cost-effective10/100 Ethernet, Gigabit Ethernet orCES/TDM access interfaces for endcustomers. All the access modules are hot swappable. It has two Gigabit Ethernet SFP/SSF-pluggable ports for connectivity to the Carrier Ethernetcore network. Redundant load-sharingAC and DC power are also hot swapp-able.

The A-2140 can be deployed as high-end CPE working with the Nokia Siemens Networks A-4000 andA-8000 series of Carrier Ethernet CoreSwitches and Nokia Siemens Networks’ASPEN management system. The A-2140 can also be used as an aggre-gation switch working together with theA-100 or A-1180 demarcation deviceto provide a very cost-effective accesssolution. Using these products in con-junction, carriers and service providerscan construct a powerful Metro infra-structure with high performance and efficiency, designed to quickly deliverprofitable communication services.

The A-2140 features 4Gbps non-block-ing switching capacity. It offers up to2,000 protected simultaneous connec-tions supporting point-to-point, point-to-multipoint and multipoint-to-multipoint services. Customer traffic can bemapped to connections using multipleand flexible rules from layer 1 (port-based) up to layer 3 (IP Address, Protocol Type and DSCP bits).

Functions

• Hard QoS supporting CIR,EIR and priority with 64Kbpsand 1Mbps granularity

• Call Admission Control(CAC), ensuring end-to-endbandwidth guarantee

• SONET-like 50ms protectionusing Fast Reroute protocolthat is much faster and morescalable than Spanning Treeor Rapid Spanning Tree protocol

• Strong and comprehensiveOAM functions including fastand pinpoint fault detection,alarm-service correlation,Ethernet loop-backs, as wellas round-trip delay, jitter andpacket loss measurement

• A full set of multicast fea-tures that support scalableand QoS guaranteed triple-play services

• Wire-speed performance

• Very low delay and jitter

• Flexible and intelligent customer traffic mappingmechanisms that allows multi-services on one accessinterface

• Up to 2,000 protected connections per device

• Strong management capability

Applications

Multi-service CPE with HighService Availability for BusinessCustomersThe A-2100 boasts a broad range ofintelligent network services, featuringgranular Quality of Service (QoS) andsub-50ms protection that enable service providers to rapidly provisionsecure Ethernet access with fully MEF-compliant Service Level Agreements(SLAs).• High revenues from multi-services• Fast trouble-shooting with the help

of strong OAM functions• Flexible customer traffic mapping

schemes• Support for single-strand fiber,

reducing fiber cost• Ease of management and service

provisioning

NEBS-compliant Multi-serviceAggregator in Central Office (CO)Suitable for CO and street cabinet de-ployment with NEBS compliance andDry Contact alarm interface, the A-2140 can be used in the CO to aggregate multiple business customersand deliver flexible, affordable E-Line,E-LAN and multicast or E-Tree Ether-net services as well as TDM services.• Rich set of interfaces with high port

density allows aggregating manycustomers of various types

• A complete solution working with A-100, A-1180 and A-210 demarca-tion devices, providing end-to-end management and OAM functions

• Single-strand fiber interfaces, reducing fiber cost almost by half

• Support for TDM grooming functions (T1/E1 to OC-3/STM-1),helping keep the existing TDM-based services unchanged whileproviding new Ethernet services.

FTTH/FTTC Aggregator forTriple-Play ServicesThe A-2140 also delivers triple-playservices in FTTH/FTTC environments.It features all the standards-based mul-ticast functions with full protectionagainst both network failure and videosource failure. Carriers and serviceproviders are able to build a single in-frastructure to serve both business andresidential markets.• Connection-oriented multicast

solution for IPTV that is more scalable than IP-based multicastprotocol such as PIM-SM

• Stringent QoS for guaranteed voiceand video services

• 50ms protection against both network failure and video sourcefailure

• Fast Channel Zapping and IGMPACL

• Support for Open Access Business Model

MEF-Compliant Service AttributesThe A-2140 delivers flexible, affordableFast Ethernet and Gigabit Ethernet access interfaces, supporting point-to-point, point-to-multipoint and multi-point-to-multipoint services. Customertraffic can be mapped to connectionsusing any combination of rules fromlayer 1 to layer 3.The A-2140 fully supports SLAs defined by MEF service definitions including:• Committed Information Rate (CIR)• Excess Information Rate (EIR)• Priority for bounded delay and jitter• Protection levels (sub-10sec or sub-

50ms)

In addition to pure Ethernet connectivity,service providers can migrate legacyTDM traffic onto their Carrier Ethernetnetwork using Nokia Siemens Networks Circuit Emulation Servicesmodules that provide ITU-T compliantE1/T1, E3/T3 and STM-1/OC-3 inter-faces.

Full Protection and ReliabilityThe A-2140 has been designed to deliver the SONET-like reliability thatcarriers demand, but with the price,performance and scalability of CarrierEthernet. Unlike other products thatbase their protection mechanism onSpanning Tree Protocol, which leads to poor scalability, long and non-deter-ministic failover time, the protectionmechanism of the A-2140 is similar to MPLS Fast Reroute, and thus canachieve sub-50ms fail-over time. It also offers an end-to-end protectionmechanism that protects against anytypes of failure within sub-10seconds,according to service profiles.

Industry-Leading Service Provisioning and ManagementSolution Nokia Siemens Networks Service Provisioningfor EthernetNokia Siemens Networks’ ASPEN solution is the industry’s simplest network management and servicemanagement platform for managingCarrier Ethernet services. ASPEN de-livers enhanced service managementcapabilities for rapid service provision-ing, comprehensive network and element management, performanceand fault management, and seamlessintegration with existing OSS applica-tions. ASPEN software allows carriersand service providers to reliably andcost-effectively manage all elements ofthe network to deliver the most reliable,scalable and cost-effective Ethernetservice offerings. Using a multi-layeredmodular architecture, ASPEN softwaresupports large, dynamic carrier-classnetworks and is ideal for minimizinghardware deployment time, serviceplanning, provisioning and monitoring.
