TWO-WAY
SERVICE
OPTION
OPERATING
SYSTEM
Being
the first in a series, the Two-Way Service Option
card
is structured with a unique
operating
system which
uses a list
of
numeric commands to accommodate the nu-
merous signalling variables found in the land mobile in-
dustry signalling standards. This operating system requires
the
operator
to first select the
OPTION
position within
the
code
synthesizer
section
of
the R-2200. The follow-
ing
paragraphs
detail
how
the
operator
accesses
these
unique functions.
The functions
of
the R-2200 provided by the Two-Way
Service Option, RTL-4161A, are accessed via a special set
of
Function Codes. Each mode
of
operation has a unique
code which must be entered by the operator. These Func-
tion Codes are listed below.

DECODE
This sequence is for any DPL (DIGITAL PRIVATE LINE)
or
Inverted
DPL
(IDPL) decoding. The
DPL
or
IDPL
modes
of
operation
are accessed by first selecting the
OPTION
position
of
the code synthesizer.

DTMF
DECODE
This sequence allows decoding
of
the standard
16
DTMF
tone pairs. Decoding
of
DTMF tone pairs
is
functional from
3 different sources. The decoder will function
OFF-THE
AIR, with a direct radio connection
or
from the External
Modulation In BNC connector (EXT
MOD), located in the
Modulation
Section
of
the R-2200 front panel. The Func-
tion
Switch must be
in
the
"Gen"
or
"Hi
Gen"
position to
decode
DTMF
tones via the External Modulation BNC
connector. DTMF decoding modes
of
operation include a
BATCH
DECODE mode. When a series
of
DTMF digits
must be decoded, a maximum
of
16
digits can be decoded
and stored in memory.
