Management of S-Access Etherlink_II devices
The equipment has integrated functions of management and diagnostics. S-Access Etherlink_II
devices can be connected to the terminal by using the RS232 interface or to a PC with the
VT100 terminal. In addition, devices can be connected to a PC network card or the Ethernet
network, to which the computer is attached. In this case, the Telnet session is used to manage
the equipment, the WEB interface being used to display the statistics.
The management and diagnostics functions allow one to configure devices and to receive
additional information, such as parameters of an xDSL link quality or G.826.
3.8.1 Management of S-Access Etherlink_II with RS232 interface
The management terminal is connected to the
MONITOR
connector, which is either on the front
panel or on the board of the device. After the power supply is switched on, press Enter. The PC
will display the main management menu.
3.8.2 Management of S-Access Etherlink_II with Ethernet interfaces
3.8.2.1 Telnet
The front panel of S-Access Etherlink_II devices contains the Ethernet connector. The local
network containing the management computer (or the PC itself) can be connected to this
connector.
Management is performed by using the Telnet session activated by a standard command:
telnet <IP-address>
in Windows 95 or above. (Any other program can be used to open the Telnet session if it
supports this protocol.)
The TELNET session is used to configure modems remotely as well as other devices connected
to the MONITOR bus of the same AccessGain shelf to which the modem is connected.
After opening the TELNET session, the user authentication is performed. Two types of users
are used: “admin” users, who can change configurations and “user” users who can only view
parameters and statistics. Initially passwords are empty; authentication in this case is not
performed and users automatically have the administrator rights. Only “admin” users can set
passwords for both types of users.
If authentication is successful, the modem main menu is displayed. If authentication fails, it is
repeated up to three times, and after it the connection breaks.
If no symbols are received by the modem over the telnet connection within 5 minutes, this
session breaks and if necessary, the modem is disconnected from the Monitor bus.
3.8.2.2 WEB
The WEB interface is used to display statistics when the S-Access Etherlink_II device is
connected to the management computer via the Ethernet interface. Any WEB browser is used
to access the WEB interface of the S-Access Etherlink_II device (the WEB browser is installed
on a user PC and is used to search and display information in the network). To display the WEB
browser, you should enter
http://X.X.X.X/.
Here, X.X.X.X is the IP-address of the device.
After the connection with the WEB interface is established, the active window of the browser
displays the following statistics:
