arg format
arg name
arg values
-v [h,l,2,2r]
voice source
h=handset, l=4-wire, 2=2-wire, 2r=2-wire wait on ring
-c [e,a,s]
channel
source
e=ethernet, a=RS-422 Asynchronous, s= RS-422
Synchronous
-o [gain]
codec output
gain
0,-3,-6 dB
-p [port]
port number
for channel source == Ethernet
-d [config]
configuration
data
for vad, tone detector, noise suppressor, and echo canceller
(in order) to turn a configuration on use '1' to turn it off use '0'
For example:
"-d 1 0 0 1"
turns vad ON, tone detector OFF, noise suppressor OFF, echo canceller ON
Note: Not all coders support all configuration!
-r [vocoder]
vocoder type
and rate
vocoder type is one of "AMBE+2", "AMBE2000", "ULAW", or
"ALAW" If the vocoder is multi-rate, pass in ",<rate_index>"
to specify the rate
For example:
"-r AMBE2000,4"
specifies the AMBE/AMBE+ vocoder with rate index 4
[ip_addr]
the IP address
to send data to
required only if the channel interface is Ethernet
VOIP Mode Command Example
adsh> dut voip -v l -c e -r AMBE2000,18 192.168.4.173
In this example the Net-2000™ VCU starts VOIP Mode using the 4-wire interface for voice and Ethernet
for the channel using AMBE/AMBE+ rate 18. It communicates with the device at ethernet address
192.168.4.173 with the default UDP port (4000).
FILE mode command:
The File mode command set the Net-2000™ VCU towork in file mode.
