With its MPLS, circuit emulation, hier- archical quality of service (H-QoS), IEEE 802.1q virtual LAN (VLAN) stacking, and wire-speed non-blocking architec- ture, the 7250 SAS has the versatility, flexibility and reliability to provide access to a whole new stream of rev- enue opportunities for service provid- ers, and feature enhancements and cost savings for private networks. These advanced features, along with extensive OAM tools, a modular design featuring hot-swappable modules with redundant configuration options, and a wide selection of interfaces, allow service providers to cost-effectively deliver a suite of user-centric VPN ser- vices, with strict, per-application SLAs.
Purpose-built for metro service applications
The 7250 SAS is purpose-built to support the data, voice and video applications that are transforming the way enter- prises conduct business. With its ad- vanced feature set, robust design and wire-speed performance, the 7250 SAS provides seamless access to services when networked with the Alcatel- Lucent 7450 Ethernet Service Switch (ESS), the Alcatel-Lucent 7710 Service Router (SR), and the Alcatel-Lucent 7750 SR.
Features
•Integrates MPLS, Ethernet and TDM technologies onto a single MEF 9 and MEF 14 certified platform:
¬MPLS includes Fast Re-Route (FRR), loose-hop label switched paths (LSPs), and Resource Reservation Protocol with Traffic Engineering (RSVP-TE)
¬Ethernet VLAN stacking per IEEE 802.1q with a variety of Fast Eth- ernet and Gigabit Ethernet (GigE) interfaces
¬DS1/E1 CES interface module sup- ports structured and unstructured packetization modes, with Tem- perature Compensated Oscillator (TCXO) and Oven Controlled Oscil- lator (OCXO) options
¬Provides less than 50 ms reliability using FRR, dual homing, dynamic bypass LSPs, and fast ring Ethernet
•Offers H-QoS with up to two levels of hierarchical scheduling and per- service class-based queuing
•Is managed by the 5620 SAM
•Offers MEF OAM, IEEE 802.1ag,
IEEE 802.3ah, service assurance agent (SAA), and Bi-directional Forwarding Detection (BFD) tool kit
•Has hot-swappable, redundant AC or DC power
•Provides dry contact inputs through a DB-9 interface on rear panel
Benefits
•Integrates MPLS, Ethernet and TDM, allowing for a variety of service options
•Extends service intelligence to the customer premises
¬Enables increased revenues through enhanced VPWS, VPLS, IP-VPN and CES service offerings by extending SLAs to the customer premises
¬Enables end-to-end solutions for Carrier Ethernet and CES when net- worked with the 7450 ESS, the 7710 SR and the 7750 SR
¬Provides scaling and operational advantages such as simplified signaling, fewer LSPs, and scalable inter-domain VPLS for large VPLS deployments
•Cost-effectively delivers advanced voice and data services in multi- tenant buildings over the IP/MPLS service infrastructure
•Delivers higher-margin services with access to a full suite of enhanced Carrier Ethernet services to support demanding enterprise applications
•Provides new CES and transparently carries TDM-based data, voice and video applications over the IP/MPLS service infrastructure, while preserv- ing the full array of Class 5 features
•Eliminates service impact and simpli- fies the process of inserting (or re- moving) a new node into an existing ring topology
•Enhances SLAs by proactively moni- toring the status of co-located equip ment in real time
•Offers streamlined management and service assurance with the 5620 SAM and the extensive OAM tool kit
