Alcatel-Lucent 1643 AMS - 3 Security administration; Overview

Multi-service application with the TransLAN
®
option board
...................................................................................................................................................................................................................................
The TransLAN
®
option board, enables the SDH network elements to provide Ethernet
over SDH, and offers variable data applications on top of the traditional TDM
applications. This results in cost-effective, simple and reliable multi-service solutions
for customers. TransLAN
®
can provide VLAN functions, and bandwidth can be shared
for different customers.
Direct LAN-to-LAN interconnect (two LAN’s)
The most straightforward application of the TransLAN
®
option board is to interconnect
two LAN segments that are at a distance that cannot be reached with a simple Ethernet
repeater, since that would violate the collision domain size rules. Both LAN’s do not
have to be of the same speed. It is possible to interconnect a 10BASE-T and a
100BASE-T LAN this way. This application is shown in the figure below:
Direct LAN-to-LAN interconnect (Multiple LAN’s)
A next step in complexity is to interconnect multiple LAN’s, more than two, at
different locations. It is possible to associate a single LAN port with two or more
WAN ports. In this way multiple sites can be interconnected, forming a fully Layer 2
switched WAN Ethernet network. This application is shown in the figure below.
