The DSC CALLING directory will accept 200 entries of vessel names and their ship station identity numbers. The
name may be one to ten characters. Letters, numbers and spaces may be used in the name but at least one character
must be entered. An ID number without a name will not be accepted. The ID number must be all nine digits of the
ship station identity number issued by the FCC with the Ship Radio Station License.
The DSC CALLING directory, the GROUP CALLING directory, the TELEPHONE and COAST STATION
directories all require the user to enter specific information in order for the DSC to send DSC calls to other DSC
equipped vessels or shore stations. The basic procedure for entering the information is the same for all of the
directories. The information stored in the directories may be changed or deleted as desired. Entries are automatically
arranged in alphabetical order according to name. A copy of the last completed entry will also appear at the top of
the list.
DSC Group Calling Directory
The DSC GROUP CALLING directory allows vessels with common interests to be listed in a separate directory and
be identified with a common group ID number. When a group call is made, all vessels belonging to that group will
receive the call.
Group ID numbers start with a (0). Presently, the procedure for obtaining group ID numbers is not clear. Please
contact the FCC for the latest information.
The DSC GROUP CALLING directory will accept 50 entries of group names and their group ID numbers. Group
names should uniquely differ from individual names in the DSC calling directory to avoid confusion when calls are
received. The name may be one to ten characters and the ID number must be nine digits. Letters, numbers, and spaces
may be used in the name, but at least one character must be entered. An ID number without a name will not
be accepted.
DSC Coast Station Directory
The DSC COAST STATION directory is used to store the names and DSC ID numbers of public coast stations
equipped to provide telephone service for ship to shore communication. The DSC COAST STATION directory is
combined with the DSC TELEPHONE directory. When a DSC ship to shore telephone call is placed, the coast station
is selected first, then the telephone number is selected.
DSC Telephone Directory
The DSC TELEPHONE directory is used to store names and telephone numbers of individuals or businesses for
direct contact through DSC equipped coast stations. The TELEPHONE directory includes the DSC COAST
STATION directory. When a DSC ship to shore telephone call is placed, the coast station is selected first, then the
telephone number is selected.
DSC Call Waiting Directory
The DSC call waiting directory logs all DSC calls that are received and not answered within 60 seconds. Calls will be
logged while busy with other communications as long as the transmitter is not keyed at the time of the call. If the call
is answered within 60 seconds the call will not be logged. When a call is logged, a message will appear in the Primary
mode display.
The DSC CALL WAITING directory will accept 100 received DSC calls. When a DSC call is received, the caller's
ID number is logged into the CALL WAITING directory with the time of day. If the caller's ID number also resides in
your DSC CALLING directory, the name will also be logged. NO NAME will appear otherwise.
Calls may be returned to any logged entry and any entry may be cleared from the directory but no user entries are
accepted into the CALL WAITING directory. A special feature of the CALL WAITING directory allows NO NAME
calls to be transferred into the DSC CALLING directory.
