Alcatel-Lucent 1665 DMXtend as an Ethernet Hub

Overview

When Alcatel-Lucent 1665 DMXtend is 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 Alcatel-Lucent 1665 DMXtend provides integrated CPE/MSPP functionality. With Ethernet over SONET (EoS), the 1665 Portfolio supports full- or sub-rate GbE packet rings. It supports Transparent (802.1q) or Stacked VLANs 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 contain enough capacity and external ports to aggregate and transmit 2.5 Gigabits per second of Ethernet traffic. The integrated packet switch can connect multiple packet rings and/or point-to-point "spokes". Alcatel-Lucent 1665 DMXtend also supports optical/Ethernet hairpinning at full-rate GbE line speed. With the LNW170, Alcatel-Lucent 1665 DMXtend provides the option of 10/100/1000BASE-T or 1000BASE-X, and 100BASE-LX 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 DMXtend provides superior Ethernet aggregation and switch capacity. Each LNW170 supports an industry leading, single circuit pack capacity of 2.5Gbps. It supports 10/100/1000BASE-T or 1000BASE-X, and 100BASE-LX 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 chose from, Alcatel-Lucent 1665 DMXtend 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. Billable services such as CIR and PIR are available in structuring Enterprise SLAs. Meeting the reliability requirements of stringent SLAs is easier given support of LCAS, which enables hitless bandwidth provisioning.

Alcatel-Lucent 1665 DMXtend 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 DMXtend capable of aggregating both Ethernet and SONET traffic with the highest levels of speed, security, and sophistication possible.
