Cause Code
Note
Description
1F21
Call Failed, LES Timeout, No Answer
LES is clearing the call because appropriate “off--hook” signaling from the terrestrial called
party has not been received by the LES within the allowed time limit.
1.
1F61
Call Failed, Terrestrial Circuit Failure
LES is clearing the call because of the detection of a failure in the relevant terrestrial circuit.
1.
1F62
Call Failed, Early Clear Terrestrial Circuit
LES is clearing the call before the “MES Connect”.
1.
NOTES:
1.
These cause codes are defined by the Inmarsat System Definition Manual (SDM).
2.
The user probably attempted to place a call too soon after logging in or too soon after the last call attempt. The
user must wait at least 20 seconds before making a mobile--originated call. Ask the customer to be patient and try
again.
3.
If this cause code occurs during call setup, there could be a problem with a particular LES channel unit. The
channel unit may need to be reset. This cause code may also occur after the call has been connected. This
problem may also occur during an NCS outage.
4.
Check which ISP or AA commissioned the phone or smart card.
5.
Verify that the customer’s smart card information (including the Ki) is entered in the ACE database at the LES. For
fixed--16--mobile calls through non--COMSAT LESs. Please dial the terminal IMN instead of the smart card IMN.
6.
Verify that the customer’s smart card information (including Ki) is entered in the ACE database at the LES.
7.
Verify that the appropriate NCS is operational. NCS channels for a particular spot beam could be blocked or
unavailable.
8.
Frequencies/channels at the NCS for a particular spot beam and for a specific service could be blocked or
unavailable/not assigned or congested.
9.
Verify that the LES is enabled for the particular service at the NCS
10. Verify that the MES/LES is lease--marked if appropriate
11. Verify that the Aero--HSD/F MES is using the new generation of signaling units
12. Verify that the MES is enabled for the particular service at the NCS; e.g., MPDS.
13. The antenna was not pointed correctly or is blocked.
14. The antenna cable is defective.
15. The M4 LES Channel Unit needs to be reset from the front panel.
