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 (e.g. 1.2.3.4,
192.168.1.1 or digi.router by default). After ensuring that your software is configured to
connect to TCP port number 23 you may then initiate a new connection.
If the connection is successful you will see a connect confirmation message 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.
