Alcatel-Lucent 1665 DMX as an Ethernet hub using LNW170

Overview

When Alcatel-Lucent 1665 DMX is equipped with the LNW170 and used as a metro Ethernet hub, it presents many advantages over other next–Generation and non next–Generation metro ADMs.

Description

At the metro edge, the 1665 Portfolio provides integrated CPE/MSPP functionality. With Ethernet over SONET (EoS), the 1665 Portfolio supports Ethernet packet rings up to 2.5 Gb/s. It supports 802.1Q or transparent (stacked VLAN) modes and can provide 802.1w rapid spanning tree restoration (802.1d also supported) whether functioning in Private Line or Packet Ring mode.

As shown in the figure above, the LNW170 contains external ports and a 9Gb/s switch with enough capacity to aggregate 2.5 Gb/s of protected spoke traffic and hand it off through one or more GbE ports to the hub. The integrated packet switch can connect multiple packet rings and/or point-to-point "spokes". Alcatel-Lucent 1665 DMX also supports optical/Ethernet hairpinning at full-rate GbE line speed. Finally, with the LNW170, Alcatel-Lucent 1665 DMX provides optical 100BASE-ZX/LX/FX and 1000BASE-X, along with electrical 10/100BASE-T and 1000BASE-T ports on one card for data traffic aggregation at the metro edge or data traffic hand-off at the metro core.

Application advantages

Alcatel-Lucent 1665 DMX provides superior Ethernet aggregation and switch capacity with the LNW170. Each LNW170 supports an industry leading, single circuit pack capacity of 2.5Gbps. It supports both optical 100BASE-ZX/LX/FX and 1000BASE-SX/LX/ZX, along with electrical 10/100BASE-T and 1000BASE-T optical ports on the same pack, allowing you to provision the most appropriate and rate-specific data cross-connections for your network. This helps you to get the most out of your investment in both metro edge and data core NEs.

With an array of Ethernet topologies to choose from, Alcatel-Lucent 1665 DMX allows you to deploy the most appropriate network for your customers' needs. Support of industry standard private lines and Packet rings, with both SONET and spanning tree protection schemes, ensures your ability to interwork with CPE networks and provide your customers with the highest level of reliability possible. R5.1 also makes such billable services as CIR and PIR available in structuring Enterprise SLAs. Meeting the reliability requirements of stringent SLAs is easier given R5.1's support of LCAS, which enables hitless bandwidth provisioning.

Alcatel-Lucent 1665 DMX provides all of these capabilities within an industry leading TDM NE that scales from DS1/E1 to OC-192 in the same, compact unit. This makes Alcatel-Lucent 1665 DMX capable of aggregating both Ethernet and SONET traffic with the highest levels of speed, security, and sophistication possible.
