Management of Etherlink_IV Devices
Etherlink_IV devices have integrated management and diagnostic functionality. The access to this
functionality is done by:
Connecting the Local Craft Terminal (LCT) or MONITOR interface (RS-232 or USB interface)
to any management terminal (PC with VT100 terminal, for example the application Hyper-
Terminal).
Connecting the local Ethernet interface to any management terminal (PC with Ethernet
network card). In this case you access with a Telnet session or you use the WEB interface to
display some statistics. Also the SNMP (Simple Network Management Protocol) is integrated.
The management and diagnostic functionality is used to configure the devices and to receive
additional information like G.826 parameters or any G.SHDSL link quality.
3.4.1 Management by Local Craft Terminal or MONITOR Interface (RS-232, USB )
Etherlink_IV NTU devices have a standard based RS-232 and USB interface for connecting any
