 Related Information

This document describes how you can establish a Telnet connection to the End−point Network Element
(ENE) or the Multi−Layer (ML) Series cards on the ENE through a Gateway Network Element (GNE) from
external networks. In order to do so, you can use PuTTY, which is an application that supports SOCKS
version 5.

The GNE serves as an intermediary for connection with the ENEs. The GNE functions as a proxy firewall and
an IP−address multiplexer, which allows connections to ENEs from areas outside internal networks.
