Remote Management; Using V.120; Using Telnet - Digi TransPort User Manual

Remote management

Digi products equipped with ISDN BRIs can be accessed and controlled remotely via the ISDN
network by using:
• a V.120 connection to access the text command interface
• PPP to access the Web Interface
• PPP to access the text command interface using Telnet
• the X.25 remote command channel
Remote access via any one of these methods can be used to reconfigure the unit, upload/
download files or upgrade the software, examine the event log or protocol analyser traces or to
view statistics.

Using V.120

To establish a remote access session using V.120, initiate a V.120 call as normal using the ATD
command. Enter "%%%" within 5 seconds of the remote unit answering and you will be prompted
to enter your username and password. Correct entry of these will allow access to the text
command interface. If the remote unit has been programmed with a Router Identity string on
the Configuration - System > Device Identity page, the Router Identity will appear as the
command line prompt. Three login attempts are permitted before the connection is reset.

Using Telnet

If you have created a PPP DUN (Dial-up Networking) entry for the remote unit that you wish to
access, any terminal program that supports Telnet may be used to establish a remote
connection.
To initiate the connection, launch the DUN. If the remote unit is configured correctly with one of
the PPP instances enabled for answering, it will connect and the linked computers icon will
appear in the Windows system tray. You may then load your Telnet software.
To configure your Telnet software you must first specify that you require a TCP/IP connection and
then enter the appropriate IP address or hostname (such as 1.2.3.4, 192.168.1.1 or digi.router by
