Making and receiving calls
To make a call, lift the handset of the connected telephone and dial the desired number. The call will
be made automatically. With the TX2LR model in the default setting, the call will be routed to either
the landline or the mobile network depending on the number dialled. When dialling a number, the
terminal will wait for 3 seconds after the last digit dialled before trying to connect the number. This
delay can be changed using CFG3. However pressing the # key at the end of the number will cause
the terminal to connect immediately.
To override the automatic line selection on an individual call, dial the prefix *9 before the number you
wish to dial and the call will be routed via the mobile network. To manually select the PSTN, press
the recall or flash-hook.
Emergency calls via the mobile network
If the SIM is locked or even if no is SIM installed, it will still be possible to make emergency calls
provided there is sufficient signal coverage. Simply dial the 112 international emergency number or
the country specific emergency number specified by your SIM (e.g. 999 in the UK).
Security features
These commands relate to the security access features of the SIM card and network services.
Commands may be entered by dialling on the connected phone or entering “ATD” followed by the
