9.2 Connection Usage
Once the Ethernet connection has been set up successfully, it is possible to transparently ex-
change data with a remote application, or to administer the LTE terminal. Possible usages are
described in more detail in the following sections.
9.2.1 Access LTE Terminal via Telnet (or SSH)
LTE Terminal can be accessed from a PC via Telnet (or SSH) for administrative purposes, and
there are two types of connection:
• Calling Telnet (or SSH) as described above in Section 9.1 connects to the LTE Terminal’s
embedded Linux system. The Linux shell provides access to files containing the network con-
figuration (see Section 9.2.4) as well as the wireless APN configuration (see Section 9.2.5).
• Calling Telnet with a dedicated port - “1234” - opens a direct link to the LTE module’s COM
port and with that to the LTE module platform. Over this interface it is possible to control the
LTE module, to for instance receive URCs, or query the current firmware version.
