5.5.1. Establishing an IP communication in RTP mode using SmartRTP.
•
Ensure that the equipment is powered up.
•
Check that the RJ45 cable is correctly connected and secured.
•
Check that the amber indicator lamp integrated into the communications module is
active.
•
Verify the status of the communications interface in the internal menu. Ensure that no
error message appears in the MAIN STATUS menu screen for this communications
module.
•
Establish the appropriate audio configuration (analog / digital input mode, gains, routing
of inputs to the codec, suitable encoding, analog output modes).
•
Set the VU meters at the most suitable adjustment point and check the input audio.
•
Enter the interface configuration and select the “RTP Point to Point” mode.
•
Select the “LOCAL MEDIA PORT” and “DEST MEDIA PORT”: local IP port (through
which the RTP audio is received) and destination IP port (to which the audio will be
sent). Both ports may be the same.
•
Configure the “SmartRTP MODE” option as “ON”.
•
Assign the IP interface to the channel.
•
Press the CALL button associated with the communications channel that is going to
use the IP interface as the connection base; this action will open the connection
configuration menu. Basically, ensure that all the fields are correct, and that they
correspond to what you have configured previously:
o
Check that the assigned IP interface is the desired one.
o
Select the encoding profile to be used in the communication.
o
Select the working mode and the reception buffer size (see paragraph 4.4 of
this manual in order to select the optimal buffer configuration depending on
your application).
o
You have the possibility of using the backup option, with its corresponding
configuration submenu in BACK UP:
Activate or not the backup option.
Select the interface to use as a backup.
Select the encoding mode. Make sure that the mode you select is
compatible with the communications interface selected, especially as
regards the associated bit rates.
Define the minimum time interval for the connection to be considered
down and the communication interface switching to be performed.
Select the number of retries to be made before considering the
communication down.
Define the minimum time interval for the connection to be considered
down if synchronization is not performed, and for the communication
interface switching to be performed.
Define the destination toward which the backup connection is to be
launched. Depending on the communication interface you have
selected as a backup, this destination will be defined by an ISDN
subscriber number, a SIP identifier (URI) or an IP address.
o
Enter manually the IP address to be called.
•
Press the CALL button on the front panel again, or select the DIAL option on screen, to
make the call.
•
Repeat the audio and mode configuration process in the other end. As “SmartRTP“
option is active, the other codec will automatically connect as soon as it starts receiving
RTP traffic, and so there will be no need to dial IP addresses or ports, accept the
incoming call or even configuring the encoding algorithm. Only when “SmartRTP” is not
active, you’ll have to repeat the calling process at the other end (because RTP is
connection-oriented, you also need to connect to the IP of the other unit on both ends).
•
You can monitor the status of the call on the OLED screen:
o
CALLING.
o
CONNECTING (depending on the communication interface and the network
status, this may be a status of extremely brief duration).
