Up VOX
Press this softkey to select uplink voice activated transmission channel
as the timeslot type for the active timeslot.
When you select
Up VOX
for a timeslot, the visual representation of the
timeslot pattern updates.

User File
Press this softkey to display the catalog of binary/bit files stored in the
signal generator’s memory. You can select a custom file from this
catalog for the data pattern or burst shape. Scroll through the listed
files, highlight the desired file, then press the
Select File
softkey.
User File
appears in the
Data
field of the display. If you have selected
User File
for configuring timeslot data fields, the selected file appears in
the
Data
field or the
B
field, both of which are located near the bottom of
the text area of the display.
User files should exactly fill the data fields in a framed transmission
(create the files to fill an integer number of frames). If the end of a user
file does not coincide with the end of a frame, data is truncated in one of
the following ways:
• Enough frames are generated to transmit as much of the data
pattern as will fit into complete frames. The remaining bits of the
data pattern (which are too few to completely fill a frame) are
truncated.
• If two files of unequal sizes are selected for the same framed
transmission, enough frames are generated to transmit as much of
the data pattern of the largest file as will fit into complete frames.
The remaining bits of the data pattern are truncated. The smaller
file is repeated as many times as necessary to completely fill these
frames. Data is truncated for the smaller file to coincide with the end
of the last frame.
• If both a user file and a PN9 or PN15 file are selected for a framed
transmission and the user file is shorter than the PN9/15, enough
frames are generated to transmit the PN9/15. The end of the PN9/15
data coincides with the end of the last frame. The smaller user file is
repeated as many times as necessary to completely fill these frames.
Data is truncated for the smaller file to coincide with the end of the
last frame.
• If both a user file and a PN9 file are selected for a framed
transmission and the user’s file is longer than the PN9, enough
frames are generated to transmit as much of the data pattern as fits
into complete frames. The remaining bits of the data pattern (which
are too few to completely fill a frame) are truncated. The PN9 data is
repeated as many times as necessary to completely fill the frames.
