Refer to Table 6 for a list of the international codes (“country code”) for the Areas/Ocean
Regions. Using the 870 country code (Single Network Access Code) automatically routes
the call to the Mini-M terminal via the proper Area/Ocean Region.
Enter the command ATD followed by a dial number from the DTE. The command is finished
with a press on the <return> button.
If the call is accepted by the Capsat® Telephone it will start the call procedure and display
the message 'Data calling' in the handset.
When the Capsat® Telephone has established the call to the LES the message 'Data-LES
connected' will be displayed in the handset. The LES now calls the subscriber data modem.
When the called data modem answers the call the message 'Data-Data connected' will be
displayed in the handset.
The message e.g. 'CONNECT 2400 ARQ' will be displayed in the handset when the Capsat®
Telephone enters the Data Mode.
The billing of the call starts when the data modem at the LES and the subscriber data modem
have finished negotiating and there is an end-to-end connection between Capsat®
Telephone and the called data modem.
If the 3 escape characters (+++) are entered the Capsat® Telephone will change from Data
Mode into Online Command Mode. In the Online Command Mode the command ATH or
ATH0 can be given to clear the connection.
If the call is billed, payment information is stored in the call log and the call duration is
displayed for some seconds in the display.
The data number has a dial format similar but not equal to the dial format for voice and fax
calls. The dial format for data numbers are as follow:
ATD<Data number><Return>
ATD
l <Short code><Return>
Leading optional fields may be left out.
Making Data Calls From The Handset
A data call can also be started from the handset. There may be situations where it is not
possible to start a data call with an ordinary ATD command from the normal DTE interface,
plug X4 on the Capsat® Telephone e.g. when running with encrypted data. The following
procedure can be used:
Enter call prefix for
automatic calls TT
Enter country code MN
Enter data number
LROTJTJT
Start the data call from
handset GP
The remaining call procedure is as described above for ordinary data calls.
