Alcatel 1650 SMC / Release 4

Introduction

.SDH (Synchronous Digital Hierarchy) is today the

dominant transport technology in metropolitan and

regional networks.

With the ever-growing demand for high-speed data

communications, Alcatel enhances its leading portfolio of

optical transport equipment with data-aware

functionality – aggregation, switching and forwarding

traffic in the proper data layer – to deliver high

performance multi-technology networking solutions.

Alcatel’s Optical Multi-Service Nodes (OMSN) –

equipped with ISA (Integrated Service Adapter) plug-in

modules – provide world-class Next Generation SDH

functionality and capacity through aggregation of

broadband multi-protocol traffic patterns such as

Ethernet, MPLS, ATM and Packet Ring.

− ability to create new revenues from today’s and

future competitive data services by enforcing and

verifying SLAs (Service Level Agreements) based on

embedded QoS (Quality of Service) patterns.

All this makes the Alcatel 1650 SMC act as an ideal

multi-protocol transport node that reveals its

outstanding performance when used as building block in

access/edge metro rings, where traffic coming from

different clients can be consolidated into common SDH

transport resources by means of cell- or packet-based

statistical multiplexing.

1650SMC Advantages

The main strategic advantages of the OMSN family are:

− Completeness: a comprehensive range of network

elements for all transmission needs, from customer

premises applications to metropolitan networks, to

long-haul and ultra long-haul terrestrial and trans-

oceanic applications.

− Simplicity: the unnumbered possibilities offered by

OMSN for network construction are provided by the

fewest building blocks. Reuse of modules between

different systems is almost total.

− Future-readiness: in addition to traditional

transmission applications, OMSN deals effectively

with data traffic patterns providing aggregation,

switching and forwarding traffic in the proper data

layer.

− Backward compatibility: OMSN guarantees full

inter-working with the existing installed base in

broad terms: from optical compatibility, to DCC

(Data Communications Channels) compatibility, to

network management. In other words, existing

networks can be upgraded with new equipment

without constraints.

Alcatel 1650 SMC Optical Multi-Service Node is an ideal

space saving, next-generation multi-service building

block for local and metropolitan networks, providing

unmatched performances for its room occupation.

1650SMC offers telecom carriers and service providers

the powerful solution to build intelligent optical

networks with integrated TDM and Packet capabilities

and achieve the optimal balance between new

competitive service offerings and traditional revenue-

generating services.

The Alcatel 1650SMC is compliant with the Synchronous

Digital Hierarchy (SDH) defined in ITU-T

Recommendation G.707.

It can be configured as a Multi Line Terminal

Multiplexer, as an Add/Drop Multiplexer or as small

cross-connect for applications in linear links, rings, and

meshed networks. In all applications various network

protection mechanisms are provided.

Alcatel 1650 SMC features all standard PDH and SDH

interfaces from 2Mbps to 622 Mbps and offers Integrated

Service Adapter (ISA) modules specifically designed for

rate-adaptive transport of Ethernet and Gigabit

Ethernet traffic patterns through the optical network

optimizing the transport infrastructure to new data

traffic patterns:

− Ethernet, Gigabit Ethernet, ATM and MPLS-based

Packet Ring switching capabilities for improved data

streams’ connectivity

− cost-effective management and transport of packet-

based data applications within the existing optical

infrastructure – no need to add specific overlay data

networks

− Cost-effectiveness: by sharing replaceable units

(common parts as well as traffic ports) among

different systems but also reusing entire shelves for

stand-alone ADM and large Cross-Connects

configurations, network operators can largely reduce

the impact of spare holding and personnel training

which typically affect overall network operation

costs. The installation of one equipment where

several similar or different ones are normally used

brings relief to costs of ownership.

− Management: no matter how the network is built or

what networking technologies are used for edge and

backbone applications (Ethernet, ATM, SDH, WDM)

OMSN delivers one unified management solution.
