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

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
