Alcatel-Lucent7250 SAS

SERV I CE ACCE S S S W I TCH

The Alcatel-Lucent7250 Service Access Switch (SAS) is afeature-richcustomer edge device,purpose-builtto increaseservice-providerrevenues and deliver a complete portfolio of Carrier Ethernet services to enterprises. The 7250 SAS is Metro Ethernet Forum (MEF) 9 and MEF 14 certified and supports Multiprotocol Label Switching (MPLS), Ethernet, circuit emulation, and operations, administration and maintenance (OAM) tools. It is managed by theAlcatel-Lucent5620 Service Aware Manager (SAM). The 7250 SAS enables service providers to increase revenues through enhanced service offerings and allows enterprise customers to expand capabilities and decrease costs.

The Alcatel-Lucent7250 SAS gives service providers a competitive edge bycost-effectivelyextending service intelligence to the customer edge. By extending service intelligence to the customer premises, the 7250 SAS allows service providers to extend service level agreements (SLAs) to the

customer premises and provides access to more enhanced Carrier Ethernet services such as virtual private local area network (LAN) services (VPLS) and virtual private wire services (VPWS), which support the increasing demands of enterprise data, voice and video applications. In addition, the 7250 SAS enables service providers to transparently carry Time Division Multiplexing- (TDM) based voice and data applications across an IP/MPLS backbone to

enable new circuit emulation services (CES) and support TDM backhauling applications such as Private Branch Exchange (PBX) backhaul and leased line replacement.

The 7250 SAS gives enterprise customers a competitive advantage by reducing their leased line costs when connectivity is provided by the service provider. The 7250 SAS also increases the services that enterprises can provide to their internal customers. All the benefits of the 7250 SAS gained by a service provider that offers services to enterprises can be realized by enterprise customers who decide to install and manage their own private networks.

With its MPLS, circuit emulation, hierarchical quality of service (H-QoS),IEEE 802.1q virtual LAN (VLAN) stacking, andwire-speednon-blockingarchitecture, the 7250 SAS has the versatility, flexibility and reliability to provide access to a whole new stream of revenue opportunities for service providers, and feature enhancements and cost savings for private networks. These advanced features, along with extensive OAM tools, a modular design featuringhot-swappablemodules with redundant configuration options, and a wide selection of interfaces, allow service providers tocost-effectivelydeliver a suite ofuser-centricVPN services, with strict,per-applicationSLAs.

Purpose-builtfor metro service applications

The 7250 SAS is purpose-builtto support the data, voice and video applications that are transforming the way enterprises conduct business. With its advanced feature set, robust design andwire-speedperformance, the 7250 SAS provides seamless access to services when networked with the AlcatelLucent 7450 Ethernet Service Switch (ESS), theAlcatel-Lucent7710 Service Router (SR), and theAlcatel-Lucent7750 SR.
