R  3_  Spot beam-spot beam handover
R 
R  After a log-on prompt, loss of P-Channel quality or a log-on 
R  renewal request, if the AES attempts to renew its log on and 
R  fails to log-on its previous GES or to the preferred 
R  alternative GES, the AES returns to the latter stages of the 
R  initial search procedure. The AES then scans the spot beam 
R  primary Pd frequencies on its current satellite to identify an 
R  alternate spot beam. 
R 
R  4_  Satellite-Satellite handover
R 
R  If during log-on renewal, the AES is unable to log onto its 
R  previous GES or to another GES in the same satellite region, 
R  then the AES enters search mode. Having selected a new 
R  suitable quality Psmc-Channel (on another satellite in this 
R  case) and update the system table for the new region (if 
R  necessary), the AES carries out a log-on procedure with the 
R  new GES. 
R

 

R  5 Log-off_ 
R 
R  The AES should log off prior to terminating its operation. 
R  This log-off may be initiated either directly or as a result 
R  of some turn-down procedure associated with the end of an 
R  in-service period for the AES. The AES aborts any calls in 
R  progress, and transmits a request for log-off to the logged on 
R  GES. 
R  8. BITE Test_________ 
R  The CFDS (Centralized Fault Display System) permits the SATCOM system faults 
R  to be displayed on the MCDU and to be printed on the printer. 
R  The SATCOM system communicates with the CFDIU through two ARINC 429 buses. 
R  The CFDIU has two operating modes: 
R  - normal mode : during the normal mode, the BITE cyclically monitors the 
R  status of the SATCOM cards and transmits this data to the CFDIU during the 
R  flight. In case of fault detection the BITE stores the information in the 
R  fault memory. 
R  - the menu mode, enables communication between the CFDIU and the SATCOM BITE 
R  through the MCDU. The BITE test can only be activated on ground.

R  (1) SYSTEM REPORT/TEST function 
R  This function enables access to all the electronic systems and to the 
R  SATCOM system. 
R  When the line key adjacent to the SATCOM indication is pushed on the 
R  MCDU, the CFDIU establishes the dialog and provides access to one of 
R  the following items: 
R  - LAST LEG REPORT 
R  - PREVIOUS LEGS REPORT 
R  - LRU IDENTIFICATION 
R  - GROUND SCANNING 
R  - TROUBLE SHOOTING DATA 
R  - CLASS 3 FAULTS 
R  - TEST 
R  - GROUND REPORT. 
R  (a) LAST LEG REPORT 
R  (Ref. Fig. 023) 
R  This report contains the internal computer faults recorded during 
R  the last flight. 
R  If no faults have occurred during the last leg, "No Fault 
R  detected" is displayed.

R  (b) PREVIOUS LEGS REPORT 
R  (Ref. Fig. 024) 
R  The PREVIOUS LEGS REPORT contains class 1 and class 2 Faults that 
R  occurred during the last 63 flights. 
R  (c) LRU IDENTIFICATION 
R  (Ref. Fig. 025) 
R  The LRU IDENTIFICATION displays the HARDWARE (P/N) and the 
R  SOFTWARE (SW/N) Part Number. 
R  (d) GROUND SCANNING 
R  (Ref. Fig. 026) 
R  This function permits the display of 1, 2 and 3 internal and 
R  external faults as they appear as long as this function is 
R  activated. 
R  (e) TROUBLE SHOOTING DATA 
R  (Ref. Fig. 027) 
R  This function permits the display in hexadecimal form of class 1, 
R  2 and 3 external and internal faults. 
R  (f) CLASS 3 FAULTS 
R  (Ref. Fig. 028) 
R  This function permits the display of all the class 3 internal and 
R  external faults.
