1677 SONET Link

NEXT-GENERATIONMULTISERVICE PLATFORM

Never before have businesses been under such pressure to provide and support multiple high-bandwidthservices while continuing to support traditionalrevenue-generatingservices. TheAlcatel-Lucent1677 SONET Link provides the means to maximize bandwidth availability and to fill that bandwidth effectively.

Meeting Expanding Demands Working with SONET

Businesses have invested billions of dollars in their SONET network infrastructures, their operations systems, and the personnel to run and maintain them. Customers, both consumers and businesses, are now demanding more services, more versatility and more bandwidth, and these demands are expected to continue to rise over the next few years. Consequently, SONET equipment is still called on to provide transport for new and existing services.

Pressure for revenue growth means that services must be deployed in the here and now, without dramatic changes to the network topology or to operational methods. To fully use and expand the capabilities of SONET, next-generationtransport solutions must be able to aggregate disparate native channels at differing bit rates, groom these signals seamlessly, and then efficiently fill the transport “pipes”.

The Alcatel-Lucent1677 SONET Link (SL) fulfills these requirements by combining the functions of legacy SONET add/drop multiplexers (ADMs), thebandwidth-groomingcapability of narrowband, wideband and broadband digitalcross-connects,and the optical

fiber-sharingof dense wavelength division multiplexing (DWDM). TheAlcatel-Lucent1677 SL offersbest-in-classport densities combined with the scalability that is necessary for gradually adding more services. What’s more, thisclass-leadingfeature set comes at a realistic price.

YOUR NEEDS

Most operators have sufficient fiber in the ground to support current and near-futureneeds, provided that the fiber is used effectively. In situations in which more bandwidth is needed, they know that AlcatelLucent has a full range ofstate-of-the-artactive and passive coarse wavelength division multiplexing (CWDM) and DWDM devices. What operators want is a network element (NE) that leverages the existing network, offers data and other services via this network, and grooms signals at the network edge. The NE must produce substantial cost savings over incumbent equipment by providing significantly increased switching capacity and port

density, while at the same time controlling Alcatel-Lucent 1677 SONET Link heat output and power usage.

Scalability for Increasing Capacity

Legacy equipment makes it difficult for businesses to scale their networks to meet ever-changingdemands for increased capacity and newhigh-bandwidthservices. Upgrading the capacity of a traditional SONET ring can be atime-consumingand expensive process, often requiring the replacement of thousands of dollars’ worth of equipment. Deploying new rings could be even more complex and difficult to manage, with even further investment in additional central office equipment to terminate the ring and to switch traffic throughout the network.

As a next-generationSONET solution, theAlcatel-Lucent1677 SL eliminatesscaling-limitationissues and additionalring-upgradecomplexity. The AlcatelLucent 1677 SL provides for future expansion as bandwidth needs grow within metropolitan and regional networks. When a new service offering is created, AlcatelLucent clients can increase support for hundreds of subtended rings from the same NE and from a variety of interfaces, to support the myriad offerings that they will want to provide.

The ability to grow networks with an installed base of equipment provides businesses with rapid returns on their investments and saves operational and

engineering expenses. Key functionality, such as OC-192,VT1.5 grooming and transmultiplexer support, allows AlcatelLucent clients to get ahead of their competition when rolling out nextgeneration services.On-board,point-to-point DS0 grooming eliminates the need for a second NE or forinter-machinetrunks. No competitor’s solution beats theAlcatel-Lucent1677 SL for integrated functionality.

BANDWIDTH MANAGEMENT

Successful businesses efficiently manage bandwidth and network resources. As large metropolitan and regional networks evolve to support hundreds of rings and terabytes of capacity in a region, it is imperative that they have the power and flexibility to switch and groom end-customerservices in the mostresource-efficientway possible. This means taking small, disparate feeds that are currently transported inefficiently and combining them into appropriately sized trunks to maximize return on investment.

The Alcatel-Lucent1677 SL grooms traffic by taking circuits from multiple interfaces and switching them onto one pipe for transport across the network. TheAlcatel-Lucent1677 SL supportsSTS-n(n = 1 to 48c) grooming to make the most efficient use of the carrier’s network infrastructure (see Figure 1). Additionally, two optional modules provide DS0 and VT1.5 switching capability, allowingfine-grainbandwidth management.Full-featuredwideband and narrowband grooming are also possible with thismodest-sizedplatform using the transmultiplexing card, and carriers may deploy this capability as needed.

In contrast to the traditional centralized model, the multi-ringtermination andbandwidth-groomingcapabilities of theAlcatel-Lucent1677 SL fit the emerging optical network model that disperses bandwidth management to the edge of the network.

INTEROPERABILITY

As businesses roll out new network equipment, this equipment must be integrated into their back-officeenvironments and under their operations support systems (OSSs), which provide provisioning, monitoring and management of multiple vendors’ NEs. Hence, the network management architecture must provide standard,user-friendly,open interfaces to allow otherthird-partyvendors to pick up support for the product. This enables them to provide comprehensive management such asend-to-endprovisioning and monitoring across multiple NEs. TheAlcatel-Lucent1677 SL is designed with the goal of deployment in acarrier-classenvironment and includes development for open interfaces for OSS integration. The AlcatelLucent 1677 SL supports interworking standards such as open systems interconnection (OSI) and target ID address resolution protocol (TARP), and these allow integration with other vendors’ systems.

MULTIFUNCTIONALITY

Any new capital expenditure must be justified by increased revenues and profitability, and the Alcatel-Lucent1677 SL provides these benefits. For example, itsmulti-ringfeature allows numerous users and circuits to be supported on one NE, thus eliminating the need for multiple NEs (see Figure 2). This decrease in equipment use results in an immediate reduction

in CAPEX, followed by ongoing savings in OPEX.

In addition to the valuable protection and restoration capabilities of SONET, the Alcatel-Lucent1677 SL offers businesses the opportunity to deliver Gigabit Ethernet services. The Gigabit Ethernet interface of theAlcatel-Lucent1677 SL makes use ofleading-edgetechnology to permit the transport of data services over the existing SONET infrastructure. This capability enables new revenue sources in return for compellingly low deployment costs.

Alcatel-Lucentwas one of the first vendors to support VCAT, the standard that enables businesses to map Ethernet
