Ethernet extension and aggregation

Overview

Alcatel-Lucent 1850 TSS-5 provides a low-cost solution for offering access to small to medium-sized enterprise end customers. Alcatel-Lucent 1850 TSS-5 can provide businesses with reliable transport for both voice and data service using DS1/E1, DS3/E3, and Gigabit Ethernet over SONET/SDH protected OC-3/STM-1 or OC-12/STM-4 lines, and aggregation of 10/100BASE-T Ethernet connections for transport over Ethernet.

Description

The following figure shows Alcatel-Lucent 1850 TSS-5s in a few different offices within the same high-rise building. With the ports for OC-3/STM-1, OC-12/STM-4, and OC-48/STM-16 lines on the VLNC50/52/55 SONET/SDH Transport circuit pack and Gigabit Ethernet ports on the VLNC40/42/42B Ethernet Aggregator circuit pack, the Alcatel-Lucent 1850 TSS-5 is perfect for the application pictured below because it can serve as a collection point for various individual business groups collocated in the same office, business unit, floor, or building. It can then transmit SONET, SDH, or Ethernet traffic to an Alcatel-Lucent 1665 Data Multiplexer, Alcatel-Lucent 1665 DMXtend, or Alcatel-Lucent 1850 TSS-5 located in the basement or in a wiring closet, or directly to a service provider's site outside of the building. Applications include DS1/E1, DS3/E3, Private Line Ethernet, and Ethernet Aggregation.

With its Ethernet capabilities, Alcatel-Lucent 1850 TSS-5 can provide secure lines for vital business data within a private LAN. Transparent Ethernet switching through SONET/SDH networks preserves on-site integrity and security of the private LAN through the larger network. Thus, multiple offices using Alcatel-Lucent 1850 TSS-5 at different sites can be connected by the same, secure Ethernet Private Line. In locations where the number of Ethernet connections and bandwidth requirements exceed the SONET/SDH bandwidth of Alcatel-Lucent 1850 TSS-5, Ethernet connections can be aggregated by the VLNC40/42/42B circuit pack onto Gigabit Ethernet connections.

Application advantage

Using the Alcatel-Lucent 1850 TSS-5 in this application results in the following advantages:

Alcatel-Lucent 1850 TSS-5 is designed as an ultra-compact, full-service TDM/Ethernet CPE, eliminating the need for larger NEs or data-specific switches and routers within the building. This is extremely advantageous as the cost of renting space in high-rise basements for telecommunications equipment is high.

• Enhances fiber up the riser distribution within the building

• Offers low-cost Ethernet and TDM Private Line transport

• Enables next generation Ethernet over SONET/SDH services such as VLANs, Transparent LANs, and Ethernet Private Lines

• Supports both electrical and optical Ethernet interfaces

• Low-cost multi-service optical BLEC/Enterprise network

• Strong transmission capability of OC-3/STM-1, OC-12/STM-4, OC-48/STM-16, Gigabit Ethernet interfaces compensates for poor quality fiber within the building

• Reliable, SONET/SDH protection of both voice and packet services

• Aggregation of VLAN and individual Ethernet connections onto Gigabit Ethernet for transport

• Integrated Ethernet switching and Ethernet compatibility with BLEC/enterprise switches
