Calling A Ship - Sailor System 5000 MF/HF User Manual

Direct Dial Calls:
If a phone number was included in the call then immediately after reception of the acknowl-
edgement the DSC call is repeated on the working frequency. This call may be used by the
coast station for channel quality evaluation. If the channel quality evaluation indicates that
communication will be satisfactory, the coast station sends a DSC acknowledgement and
starts dialing the subscriber number. Dialing tones may be heard in the speaker or handset.
When the handset is placed on hook after a Direct Dial call a DSC call indicating 'End of call'
is send to terminate the connection. The coast station may respond with a DSC call indicat-
ing the chargeable duration of the connection.
