more information, but will be executed when
entered.
• Parameters of the same command may be
chained together as a single entry, with each
parameter separated by a space. The chain
cannot exceed 80 characters, including spaces.
Example: to configure CTS and DSR in the data
port async channel, you could enter the
following string:
data=as cts=on dsr=on
.
(NOTE: The equal sign = may be replaced by a
space.)
List of Parameters
Following is a list of parameters associated with each
of the commands marked with an asterisk in the list
of commands.
AInterface
INput_gain (dB)
-6 through 22
Output_Attn (dB)
0 through 28
OPeration (E&M)
2_wire, 4_wire
Signalling_format (E&M) DC, AC-15, Pulsed_DC
IMpedance
600 ohms, Complex
RINGTYPE (FXS)
2-4_interrupted,
1-2_interrupted
RINGFreq (FXS)
25_Hz, 50_Hz
Extra_gain (E&M 4-wire)
None, 7 dB
Example:
>AI IN=-6 OUT=4 RING T=2-4
IMp=600<cr>
will set the FXS input gain to -6 dB,
the output attenuation to 4, the ringing type to 2-4,
and the line impedance to 600
Ω
NOTE: If your equipment is operated in the U.S.A.
or Canada, input and output levels must be
set to 0 dB. In other countries, follow the
standards of the country wherein the
equipment is used. If there are no specific
standards, set the input and output levels of
your equipment to match the interfacing
telephone equipment.
Be sure to separate each command in the string by
a space.
The parameters above become effective
immediately when entered, but are not stored in
EEPROM (nonvolatile memory) until saved. To save
the newly set parameters in EEPROM, type
>SA

Rate (bps)
1200, 2400, 3600, 4800,
7200, 9600, 14400,
19200, 28800, 38400,
57600
Data_bit

Parity
None, Even, Odd,
Mark, Space
Flow_control
None, Xon/Xoff,
CTS/RTS

Disable/Enable
Example:
>AS RA=7200 D=7 P=O <cr>
will
set the async channel rate to 7200 bps, the number
of data bits 7, and parity to odd.
Be sure to separate each command in the string
with a space.
To save the newly set parameters in EEPROM,
