V.8 The ProntoNet operating as IP codec (NET = IP)
The operation of the ProntoNet as an IP codec offers two operational modes:
UNICAST and MULTICAST.
V.8.1 UNICAST communications
The term UNICAST is used in the networking world to refer to the connection to
a single destination. Applied to the ProntoNet, this is when a point-to-point
connection is created between two units bi-directionally.
V.8.2 Using line 2
It is possible to use line 2 for a unicast unidirectional TX communication, but the
unit will send the same audio as line 1. That is, encoder 2 won’t be used for this
purpose. This option is available from version 3.3.1.
V.8.2.1. Establishing a UNICAST connection from the ProntoNet
The procedure for establishing a connection is very similar to that of making an
ISDN call; we enter the call initiation menu by pressing the CALL 1 key and enter
the IP address of the unit we wish to connect to. As we have already
mentioned, the audio data connection is bi-directional (as in an ISDN codec) and
we need two connections, one in each direction. For this, the ProntoNet that
receives and accepts the call will automatically call back to the originating
ProntoNet and establish a reverse connection.
This is all represented in the following diagram:
