5.1.1 Menu Operation
Menu selections are accomplished by entering the capital/uppercase letter
displayed for the required option and pressing return. The display will
pass to the next associated sub menu or prompt for operator input. See
Section 2.1 for a full description of control terminal operation.
The following sections provide information on the operation of the various
menu commands. Note that the characters in brackets to the left of the
menu, except at root level, indicate the command characters entered to
reach the current point from the root menu. Where data input is required
this may be entered in binary, decimal or hexadecimal with each entry
having a B, D or H suffix as appropriate. If no suffix is appended 'Decimal'
will be assumed.
The 'Maintenance' and 'Fault' sub menus are fully described in Chapter 6.
Menu structures for cards other than Dual LIU cards fitted in ports 1 and
2 may be found in the relevant reference manual for the card.
Root Menu
When the multiplexer is operated in secure mode, the root menu may be in
one of two states:
a) Open
b) Closed
Closed Mode
The operator can only select the 'Open' option at this point and a prompt
for a password will then be obtained.
() Open >O
password >
The password will be entered with the echo suppressed so that the
operators terminal does not show the password. Once the correct
password is entered the standard root menu will be obtained.
