Chapter 8 – Auto Dial-in Feature
Introduction
The auto dial-in feature enables the MultiConnect IP to act as a Telnet client thus facilitating the serial
device to access any Telnet/terminal servers on the IP network (over the built-in modem interface). Once
the session (Serial Client to Server) is opened successfully, it allows two-way traffic between the serial
device and the remote server.
The MultiConnect IP, acting as a Telnet/RAW-TCP client, accommodates the following features when
configured:
• Support to open the session using Telnet client (residing in the MultiConnect IP) in Telnet Mode or
RAW Mode.
• Support to open the session to the specified port from a Serial Command prompt (Manual Dial-in).
• Switching between a Command prompt and a Dial-in session when the session is in Telnet mode.
• Support to open the session to the configured port directly (Serial Auto Dial-in) whenever the serial
port is free.
Prerequisites

The following items must be configured in order to use the dial-in feature:
• Enable Auto dial-in globally on all the serial ports.
# set serial auto-telnet enable
