VALID DPL CODES
• AlB ENCODE
Figure 3-24 shows a display for page I of the menu. To
select sequence input, enter a number from I to 4. Enter
Tone A and Tone B frequencies. Each frequency has a
maximum value of 20,000 Hz with a resolution of 0.1
Hz. The system responds to changes in the tone fre-
quency to allow the next complete signaling sequence to
be executed with the new tone frequency. The majority
of two-tone pagers use the first two fixed sequences
listed in the tone sequence table. The operator cannot
change the first two sequences but he can change the last
two. Each delay entry has a maximum value of 10
seconds. The system responds to new entries during an
active sequence to allow the next complete signaling se-
quence to be executed with the new timing mformation.
For triggered sweep on the oscilloscope program the
scope trigger delay to a maximum
10
seconds (0.001
second resolution).
If
time entered exceeds Tone Se-
quence time, the oscilloscope will not trigger. Enter
000.0 to disable trigger delay.

DPL DECODE DISPLAY
• TWO-TONE SEQUENTIAL PAGING
Program a two-tone pager access sequence with Tone A
and Tone B frequencies, tone durations, and time be-
tween tones as defined in figure 3-24. Select Tone Se-
quence mode for the code synthesizer, AlB sequence
all
the Signaling Sequence DISPLAY, and Generate
FUNCTION. The timing format for this mode consists
of Tone A for the programmed time, followed by the
programmed delay, followed, by Tone
B
for the pro-
grammed time, followed by the second programmed
delay. This sequence will repeat in continuous position
but generate only a single sequence in burst position.

place the code number. Table 3-6 lists the valid DPL

TONE ENCODE
Figure 3-25 shows an encode display for page 2 of the
menu. Select either 5-tone or 6-tone paging. Table 3-7
lists the cap code digits and their frequencies. Enter the
cap code digit for the desired output sequence. The code
has a preamble tone number followed by a 5-digit se-
quence number. An X automatically appears at the end
of the cap code. The system responds to changes in the
cap code to allow the next complete signaling sequence
to be executed with the new code information. The sixth
or X tone may not be transmitted by selecting the 5-tone
sequence. If the tone is not transmitted, a delay equal to
the normal tone X time is inserted. With the MODULA-
TION switch in continuous position, the output consists
of the preamble tone followed by a continuous cycling 5
or 6 tone sequence. Cycling terminates only when the
switch is moved to the off position or the mode is
