B. Logging On and Off
Using the MCDU, you can log on to the satellite network manually
or automatically:
• Manual Logon—constrains the logon to use a s
atellite that you select
• Automatic Logon—logs on using the best available satellite as defined by the ORT
If spec
ified in the ORT, the initial system lo
gon happens immediately after the
A781-200 system powers up, with no MCDU input required. If the ORT is not configured
as su
ch, you must initiate the logon from the MCDU (MANUAL LOG-ON or AUTO
LOG-ON command). For more information, see "ORT Overview" on page 3-8.
