Chapter 10, Signaling Encoder (AF Generator 2)
AMPS-TACS NAMPS-NTACS Encoder
Data Rate
This setting determines the rate that the FOCC and FVC information are output.
Operating Considerations
This field specifies the data rate for the signal being decoded, and must be set
before using the AMPS-TACS/NAMPS-NTACS Decoder.
DSAT (FVC)
This field is available only in NAMP-NTAC mode.
This field is used to specify the 24-bit digital supervisory audio tone (DSAT)
sequence. The seven standard sequences are: 2556CB, 255B2B, 256A9B,
25AD4D, 26AB2B, 26B2AD, and 2969AB. (These codes are the inverse of the
seven DST codes.)
DSAT is output continuously when
Send DSAT is selected, and is only stopped
when
Stop DSAT is selected. If message or DST information is sent using Send,
the DSAT signal is temporarily interrupted until that information has been sent.
(The
Status: field in the upper-right corner of the screen indicates what type of
data is being sent.)
