The purpose of this page is to initiate a PAST, to enable/disable a voice
loopback on a selected (physical) channel, to enable/disable a test of the
cockpit voice call light for a selected (logical) channel, and activation of the
cockpit voice go-ahead chime test. See Figure 6-7 for example pages.
(b) Data Fields

Line 1
a
This line displays the title of the page, SAT--N, beginning in column 10,
where N represents 1 or 2 to indicate a single SDU (N = 1), SDU No. 1
(N = 1), or SDU No. 2 (N = 2) as determined by the settings of
configuration pins TP12E and TP12F.
b
If there are current failures to report after the execution of a PAST,
columns 20 thru 24 display p/t in small font, where p represents the
current displayed page, and t represents the total number of pages
needed to show the current failures. The display of the slash is always
in column 22, with p right-justified to the slash and t left-justified to the
slash.

This line displays the message TEST IN PROGRESS 60S beginning in
