Services You Can Bank On
As we’ve seen, the Alcatel-Lucent 7450 ESS provides the kind of technological advances required to operate in a service provider environment. Table 2 describes how the Alcatel-Lucent 7450 ESS enables Ethernet services that address the service provider’s inter-region and nationwide requirements.
The Alcatel-Lucent 7450 ESS can also be a key component in a network design that calls for service interworking between frame relay/ATM and Ethernet. The Alcatel-Lucent 7450 ESS can deliver and receive Ethernet traffic from the Alcatel-Lucent 7670 Routing Switch Platform (RSP), which handles the service interworking. With service interworking, providers can deploy the most appropriate access technology at each site in the network. This enables them to maintain current service offerings where appropriate, while provid- ing new Ethernet-based services over the same VPN. The ability to provide a unified frame relay/ATMto Ethernet VPN is critical for service providers who want to offer high-speed Ethernet services, and protect their existing network investment and customer services.

ACompelling Business Case
The numbers are in and the business case is clear: deploying Ethernet business services using the Alcatel-Lucent 7450 ESS is a wise investment. Alcatel- Lucent’s analysis, conducted using fairly conservative estimates for growth, indicate that even considering the initial setup costs, service providers can expect to achieve a positive cash flow within the first two years of implementing Ethernet business services using the Alcatel-Lucent 7450 ESS.
Whether the need is for VPLS or VLL services alone, or these services bundled with Internet access, the business case is solid. Major factors contributing to this positive projection are the operational efficiency improvements and service assurance enabled by Alcatel-Lucent’s service-aware OA&M toolkit, template- based provisioning and the superior service management support provided
Name | Description | Advantages Offered |

BUSIN E SS SERVICE | S | |
| | |
Ethernet virtual leased line (VLL)
Point-to-point Layer 2 service interconnecting two sites. Also known as Ethernet private line (EPL) or Ethernet line (E-line).
Provides similar functionality to a frame relay or ATM leased line service, but with potential cost savings and ease of use. In demand by enterprises who want to focus on Ethernet offerings.
Ethernet virtual private line service (VPLS)
Multipoint-to-multipoint Layer 2 Ethernet services that interconnect many sites as if they were part of a single LAN. Also known as transparent LAN service (TLS) and Ethernet LAN (E-LAN)
A premier service providing high bandwidth capacity (greater than T1/E1), multiple QoS levels, scalability and the ability to offer rigorous SLAs. VPLS expands the next-generation VPN service market.

Consumer Triple Play residential services | Scalable aggregation of subscribers using Ethernet/ |
| VPLS. Initial aggregation may be done via any access |
| node, such as an Ethernet DSLAM or an Ethernet passive |
| optical network node, with handoff to the 7450 ESS. |
Provides an alternative to ATM or optical aggregation of traffic from access nodes. Facilitates bundling of services, which in turn can aid in customer retention.
Internet access and IP-VPN backhaul | Services delivered using a combination of the Alcatel- |
