QFO-C Card Provisioning
The card is provisioned through the craft port on the
SCU or by the FCD. Detailed procedures for
provisioning the QFO-C start on page 11 with the
section labeled Fiber (QFO-C) Main Menu. The
screenshots are accompanied by steps to assist in
provisioning the unit. Table 8 includes a list of the
functions that may be provisioned in the QFO-C card.
Four-Character Display (FCD) Guidelines
This section provides guidelines for using the FCD
menu interface for configuration, provisioning and
system maintenance.
Menu Structure
The menu structure for a card is a multi-layered menu
tree. Each menu level consists of menu elements,
which may be either a main menu or a sub-menu item.
Sub-menus are menu elements that when selected
descend down to the next menu level. Menu items
consist of two types:
• Read-only – Elements that display information
that may change based on the status of the unit,
but are not changeable directly by the user, for

Navigating the Menu Structure
The three-position, return-to-center MODE/SELECT
toggle switch on the SCU provides the FCD menu
interface. The FCD displays strings four characters at
a time. A string greater than four characters long is
displayed as 4-character sub-strings for 1 second per
sub-string. The string repeats when the end of the
string is reached.
Four input values are available from the switch:
Section 61181300L1-5C, Issue 3
example, "STAT OK."
• Read/write – Elements that display information,
but the value may be altered by selecting the
item, for example, "DSX EQ 134 FT." The user
can select the item and change its value.
• MODE – press the switch in the MODE direction
and release it within 1.5 seconds to toggle among
selections on the current menu. The switch must
be held for at least 24 milliseconds.
• SELECT – press the switch in the SELECT
direction and release it within 1.5 seconds to
select a menu item.
The switch must be held for at least 24
milliseconds. If the SELECT switch is held for
more than 1.5 seconds, the input is ignored.
