OXXO is a common call sign for all Danish ships. An OXXO telegram is an important message sent to all Danish ships from Danish authorities. This message may be a warning in a crisis or wartime situation about dangers of navigation in certain areas, along with guidelines on precautions to be taken in such situations. Alternatively, it could be an important message to all Danish ships, such as instructions for casting absentee ballots in connection with elections in Denmark.
In the so-called FLEET NET, which is part of the Inmarsat EGC (Enhanced Group Call) service, it is possible to send the same message to all Inmarsat-C terminals with a common ENID (EGC Network Identity) number.
Danish ships with an Inmarsat-C terminal and a call sign ending in 10 (primary station) are assigned ENID 28941.
The ENID coding is performed by NSSLGlobal, which, through the EIK ground station in Norway, sends a signal to the ship's Inmarsat-C terminal with automatic encoding of the number. The ENID number is only encoded if the terminal is open and no other transmission is in progress at the time. Therefore, the encoding signal is sent twice. NSSLGlobal does not receive confirmation that the ENID number has been encoded in the ship’s terminal.
If the ship's printer is turned on, the following message will be printed once the ENID number is encoded (depending on the brand):
| REPORT (nummer) |
Page (nummer) |
UTC time: (dato) |
(Klokkeslæt) |

Typical Errors
In some cases, ENID 28941 may not have been coded into the ship’s Inmarsat-C terminal due to poor reception conditions, accidental blocking of the number on board, or other configuration changes.
Additionally, the number may have been deleted during service/repairs, and the primary station (10) and secondary station (11) may have been swapped.
To check if ENID 28941 is coded/active in the primary station (the one with an INM-C number ending in 10), do the following:
1. In the menu under OPTIONS-CONFIGURATIONS-END, you can see which ENID numbers are coded and whether they are ENABLED or DISABLED. ENID 28941 must be ENABLED.
2. Under ROUTING, you can see whether EGC reports are saved on a disk or printed.
There should be an X next to PRINTER.
The menu design may vary depending on the terminal’s brand.
If ENID 28941 is not on the list, a new coding must be performed by NSSLGlobal. It is possible to contact NSSLGlobal here (preferably by email):
NSSLGlobal.com
Email: info.dk@nsslglobal.com
Phone: +45 36 70 36 03
It would be very helpful to provide information on which satellite the terminal is logged on to. A new coding directly to the relevant ship will then be performed via EIK.
