The Alcatel-Lucent 7705 Service Aggregation Router (SAR) delivers industry-leading IP/MPLS and pseudowire

capabilities in a compact platform that has the ability to groom and aggregate multiple media, service and

transport protocols onto a normalized, economical packet transport infrastructure.

The 7705 SAR is extremely well suitedto the transport needs of the evolvingmobile radio access network (RAN). Theplatform delivers strong convergencecapabilities in the mobile RAN withnative service processing of 2G, 3G and4G traffic. In addition, the platform canprovide a powerful solution for wire -line aggregation and routing in carrierand enterprise applications. For example,the 7705 SAR can be deployed in a T1/E1private line multi plexing environment.

The 7705 SAR owes much of its develop -ment heritage to the Alcatel-LucentService Router (SR) product line. Sharingmuch of the market-leading feature setof that product, the 7705 SAR brings apowerful, service-oriented capability tothe RAN, but in a form factor and pricepoint that are particularly appro priatefor cell sites and hub locations. Withend-to-end service creation under theAlcatel-Lucent 5620 management port -folio, the 7705 SAR greatly aug mentsthe IP/MPLS RAN transport solutionfrom Alcatel-Lucent.

Industry-leading scalability and densityis provided in the 8-slot, two RU versionthat supports up to 96 T1/E1 any service,

any port (ASAP) ports. On the networkuplink side, media connectivity optionsare: Ethernet, Fast Ethernet (FE), GigabitEthernet (GE), or n xT1/E1 multi-linkpoint-to-point protocol (MLPPP). Theplatform can be optionally configuredwith a redundant core control moduleand uplinks. The 7705 SAR-8 has eightslots; two are allocated for controlmod ules, with the remaining six beingavailable for user traffic interfacemodules. The 7705 SAR has a compactmodular architecture, constructed toallow flexible use of line cards foroptimization based upon per-siterequirements.

With the modular architecture comesadditional resilience and flexibility. Thesolution can optionally support 1+1 fullyredundant control and fabric cards.Each line card has dual paths to theactive and standby control and fabriccards. Each slot can be used for anyline card, removing the burden ofcomplex pre-engineering and futurescenario planning. The two line cardssupported in R1.0 are a 16-port ASAPT1/E1 card and an 8-port Ethernet card.

The ASAP card supports ATM, inversemultiplexing over ATM (IMA), TDM andMLPPP. The Ethernet card has six portsof auto-sensing 10/100 Base-T ports plustwo further ports supporting 10/100/1000Base TX with small form factor pluggableoptics (SFPs). Each slot is connected tothe switching fabric via a 1 Gb/s link tohost existing and future interface types.

Service Aggregation and NetworkingIn order to provide the most efficienttransport solution, the 7705 SAR employspseudowire (PWE3) encapsulation meth -ods to map services end to end. Theuse of pseudowires ensures that the keyattributes of the service are maintained,while using a cost-effective packetenvironment to aggregate services.

The 7705 SAR supports draft-ietf-pwe3-cesopsn for the encapsulation and trans-port of TDM traffic, for example, 2G TDMservices. The use of circuit emu lationservice (CES) ensures that only the activetimeslots are transported, keepingbandwidth usage to a mini mum. The

7705 SAR also supports rfc-4717 ATMpseudowires (also known as draft-ietf-pwe3-atm-encap). N:1 cell mode fortransport of ATM-based ser vices issupported. Multiple access ATM portsare bundled together to attain higherspeeds using IMA. The IMA pro tocol is terminated on the 7705 SAR andonly the cells containing user databelonging to a VC/VP structure aretransported.

In addition, the 7705 SAR supports rfc-4448 Ethernet pseudowires for the transportation of Ethernet trafficacross the packet network. In order tooffer greater scalability, all the trafficout of an Ethernet port can be carriedover a single Ethernet pseudowire or,alterna tively, a pseudowire can becreated for each VLAN that is assignedto a differ ent service or end-customer.

When dynamic signaling is deployed, theend-to-end pseudowire is establishedusing T-LDP and the MPLS tunnel viaLDP. In addition to efficient label distri -bution protocol (LDP)-based dynamic

signaling, static provisioning of boththe MPLS tunnel and the pseudowire is also supported.

Quality of Service and Traffic ManagementIt is critical to maintain the end-to-endquality of service (QoS) for packet traffic.Not all types of traffic have the same setof requirements. Voice traffic in particularrequires low latency and jitter (latencyvariation) and also low loss, whereas datatraffic has less strin gent delay require -ments but is very sensitive to loss, aspacket loss can seriously constrain appli -cation through put. In order to offer the required treatment throughout thenetwork, traffic flows with differentrequire ments are identified at the accessand marked in-line with the appropriateQoS metrics. Traffic classification andmarking is carried out based on thefollowing:

Classification (Layer 1/Layer 2/Layer 2.5and/or Layer 3 header):

Timeslot/port

Ethernet port/VLAN

Note: The 7670 RSP supports ATM and Ethernet pseudowires. The 7710/ 7750 SR also supports ATM and Ethernet pseudowires, support for TDM pseudowires will be added in R 6.0.

The 7705 SAR utilizes extensive trafficmanagement policies to ensure fair nesswith detailed classification and hierar -chical scheduling including minimum/maximum, profiled, round robin andstrict priority scheduling and multi-tierpolicing to differentiate and prioritizeindividual services and flows.

Operations, Administration and MaintenanceIn order to ensure continuity of services,the 7705 SAR has a full set of OAMfeatures including:

LSP ping

LSP traceroute

SDP ping

verifies tunnel connectivity, roundtrip delay, etc.

Virtual circuit connectivity verification(VCCV)

verifies service level existence,round trip time, etc.

extends OAM to pseudowireservices

Service Assurance Agent (SAA)

runs in background, automaticallyand regularly collecting networkhealth information from OAMmechanisms such as VCCV andmonitoring for problems such asSLA transgressions.

These features, when under the controlof the 5620 management portfolio,ensure rapid fault detection as well asefficient trouble-shooting. In particular,SLAs can be monitored, transgressionsdetected and reported via the SAA.

SynchronizationCell sites rely on the backhaul networkto provide synchronous interfaces forthe proper delivery of data. In addition,cell sites may rely on the network inter -faces as stable references with which to derive radio frequencies (RFs) and in order to ensure reliable subscriberhandover between cell towers.

The 7705 SAR supports external refer -ence timing, line timing and adaptivetiming in R1.0. The adaptive timing isfully capable of offering end-to-endsynchronization. In addition, the 7705SAR is completely hardware-ready tosupport IEEE1588v2. This IEEE standarddefines a method to minimize the effectsof delay and delay variation (jitter).This is accomplished by a combinationof built-in architectural features andalso powerful QoS mechanisms to mini -mize the delay experienced by synchro -nization traffic. This is a cornerstone ofthe design of the 7705 SAR. A built-inStratum-3 clock is available in the con -trol module to assist in synchronizationmaintenance.

Features

Cost-effective migration from E1/T1-based backhaul to packet-basedtrans port, leveraging Ethernetservices over a wide range of firstmile media.

Resiliency and redundancy including:one-for-one hitless control andswitch card failover, synchronizationredundancy, network uplink resiliencyand redundancy of power feeds.

Powerful, service-aware OAM capa -bilities complemented by the 5620management portfolio for GUI-basednetwork and element configuration,provisioning, fault and performancemanagement.

Dense adaptation of multiple con -verged services onto an economicalpacket infrastructure.

Extends service routing IP/MPLS capa -bilities to the cell site/network edge.

Dynamic tunnel signaling for scaling,ease of establishment and resiliency.

Benefits

Transition from PDH-based connec -tivity to Ethernet-based can greatlyreduce recurring operating expendi -tures (OPEX) such as line lease costs.

Advanced resiliency features lead to improved network uptime, whichcan positively impact customer reten -tion and allow critical services to beoffered for increased revenue.

Modular, flexible architecture alle -viates the burden of complex pre-engineering and future scenarioplanning.

Rapid fault detection and powerfulcommissioning and troubleshootingtools can improve productivity ofoperations staff and reduce networkdowntime.

Multiprotocol and convergence capa -bilities reduce equipment instancesneeded to carry multiple fixed andmobile traffic streams.
