Imagination on Light - can youimagine?

Can you imagine? - Billions andbillions of colourful photons - movingwith their natural speed which is thespeed of light and each of them iscarrying the essence of modern life -information, voices, images.

Our modern way of life isinconceivable without -communication - information moving- being made available at every endof the globe, take it or leave it -shared experiences, immediateknowledge and instantaneousresponse, expanded horizons andzoomed magnifications, small-talk ordeep discussion, creation of wealthand virtual movement of assets,

moving images and still pictures andand and ...

Being in touch and - or - being ableto stay in touch gives the opportunityand freedom to communicate bywhatever means deem appropriateand - or - necessary. Naturally thisdoesn't come about just on its own.This requires an infrastructure beingmade available anywhere at anyspeed, anytime in any shade.

The solution to this infrastructurechallenge is optical networking -optical because it is the only meansto efficiently carry the amount ofinformation requested over longdistances - networking becauseinformation has specific sources anddefined destinations.

Challenges on Light

Requests for new bandwidth, requestsfor more bandwidth, requests forbandwidth somewhere else or someother time - challenges on light to bemet.Permanent changes in demands forbandwidths call for immediatefulfilment - customer satisfaction ismandatory to establish and maintaina strong competitive position. Andeventually we are not talking justsmall scale - this happens on everyscale imaginable - access, metro,backbone - regional, international,global - restricted only by the naturalreach of mankind.Hence, the underlying infrastructuresneed to respond to these demands,i.e. to support the full range ofservices, to enable immediateintroduction and provision of newservices, to facilitate new networktopologies, to optimize network costthrough high-speed transmission and

wavelength multiplexed exploitationof fibres, and finally to manage andadminister all this efficiently andeffectively - and all that withinvestments closely synchronized torevenues.

Impossible ?

Flexibility on Light

Not at all - Alcatel's answer to this isits Optinex™ product familycomprising network elements of thespeed, capacity and size you needand a management system enablingfast and safe management andadministration of the resultingnetwork.

The flagship within this family is theintelligent Alcatel Optinex™Multiservice Core Gateway (OMSG) 1674 Lambda Gate,because it concentrates up-to-nowunreached capacities in one singlenetwork element.

The 1674 Lambda Gate evolvesaccording to your needs andrequirements. The variety of interfacesoffered by the 1674 Lambda Gatecovers the entire range of interfacesof current deployments, i.e. STM-16,STM-4, STM-1, 140 Mb/s PDH, andfeatures in addition Alcatel's highspeed interface at 10 Gb/s STM-64 carrying VC-4-nc signals. All interfaces allow any concatenation(VC-4-4c/16c/64c) compliant withthis interface. Further, the 1674Lambda Gate offers optical channelnetwork interfaces of 2.7 and 10.7Gb/s and transparently processes theoptical channels according to theemerging standards - and, foraccessing the optical layer, the 1674Lambda Gate provides userinterfaces to serve any 2.5 and 9.9Gb/s SDH signal on optical channels.The capabilities of the 2.7 and 10.7 Gb/s interfaces allow a trueprocessing of optical signals in thesystems and even groom andsegregate any signal above

150 Mb/s into and from these opticalsignals. With the 1674 Lambda Gate,we have the world-wide first systemnot only supporting high speed linksbut also offering the facilities toflexibly manage many of them. Thus, the 1674 Lambda Gate addsconsiderable value to either theoptical network or the SDH network,but the 1674 Lambda Gate displaysactually its unique advantage inbetween them, allowing your networkto evolve smoothly - either way.

Hence, the 1674 Lambda Gateserves• on the one hand as a gateway

between the optical network andexisting installations ofSDH/SONET networks and thus,increases the value of your legacyand

• on the other hand in conjunctionwith our DWDM product family asthe flexibility point for opticalchannels in the optical network.

Not being taken too lightly

The 1674 Lambda Gate is truly across connect and has - of course -the rich feature set required from thisnetwork element • real time signal processing• real time signal and performance

monitoring• efficient protection and restoration

capability • blocking-free cross connecting

capability between any ports• growth on demand and

scaleability aligning revenues andinvestments

• real time management• in-services upgrades and

extensions• support of all conceivable

networking applications

• effective management of IP andATM traffic on the SDH layer

• and and and

Within the network, the 1674 Lambda Gate grows accordingto your needs in serving yourcustomers, but not in a single spot.The innovative system-internalcapability of being able to bridgeconsiderable distances betweensubsystems using high speed fibreinterconnections, allows a distributedinstallation giving you access to thesystem exactly where you need it -and it's still one system. We namedthis capability "room protection".

The 1674 Lambda Gate comes inthree variants to optimize networkcost and applications.

Light on Light

Light on light is the low footprint lowcapacity high speed variant of the1674 Lambda Gate R1 - especiallydesigned for interconnecting 2.5 or10 Gb/s rings and dropping some ofthe traffic. A typical applicationinterconnects three 10 Gb/s ringsfrom which 20 Gb/s are dropped -and all this in two racks includingredundant common parts !!

High on Light

High on light is the low footprint highcapacity high speed variant of the1674 Lambda Gate R1 developed forhigh capacity applications as it cancross connect up to 5 Tb/s, i.e. 5120 Gb/s, even offering access tothe optical layer through an OpticalChannel Interface (OCh-I/F). This machine has thus a variety ofapplications - it is deployed inmeshed networks, in ring networksand in a combination thereof. It serves any need you may come upwith through its flexible applicationunder any circumstances - it is thepoint of flexibility you need in yournetwork.

Deep into Light

Deep into light you go with the 1674 Lambda Gate R2. Next to allthe features available in the 1674Lambda Gate R1, this system offersoperators interfacing capabilities onoptical channels. Hence, theincreased effectiveness provided bythis capability results in an optimizednetwork design where optical traffic iscross-connected on the optical layeror on the SDH layer - your networkdesign determines the choice.
