Telnet Connection - Vidicode V-Tap ISDN PRI Manual

9 Telnet connection

The V-Tap can be accessed with the Telnet (Teletype Network) protocol.
Telnet is an older protocol to access devices remotely with a simple
terminal and then perform maintenance or change settings. Telnet also
uses the TCP protocol with the fixed port number 23.
Running a Telnet client program on the PC makes it possible to connect
to the V-Tap.
After connecting, the V-Tap Name is shown, and some debug
information is constantly sent; Opening and closing of the Tunnel
connection and, when an SD card is used, the opening and closing of
files on the card.
Further there are two commands that can be entered with Telnet:
The command ATMENU will first ask you to enter the Login Password,
which is the same as the one used for web access (default "admin"), and
then brings you in a remote maintenance menu. Once inside the menu,
the tunnel function and SD card storage are stopped.
The menu gives the user the possibility to change the settings, reset the
file counters on the SD card, reset to factory settings and change the
clock. Normally, there is no need to use these functions over Telnet.
The command ATDEBUG is a toggle to enable and disable the output of
more debug information. This is further not described in this manual.
The command ATDTEST jumps to the D-channel trace facility. The ISDN
D-channel is outputted and can be captured and interpreted for debug
purposes. Recording is still possible in sniff mode. In pass-through mode
recording is stopped, and only a trace is made.
A better way to get a D-channel trace is described further on in the
manual in the chapter D-channel trace for debug.
Telnet is disabled by entering ".DT" in Special Settings & Commands.
