IV.3 NET: Selecting a communications port.
The ProntoNet has three different communication ports that allow the unit to
operate over three distinct types of network: IP, ISDN and dedicated digital
networks (X21 port).
The NET option is only available if the lines are not already connected. If they
are busy, the display will show the following text:
Each NET type selection will of course have their own set of configuration
parameters, as will be seen next.
IV.4 ENC: Encoder algorithm selection menu
From this option we can choose the audio Encoder algorithms. Note that the
ProntoNet can operate as a DUAL codec when ISDN is selected as the
communications interface. In this case, it is possible to have two simultaneous
communications that are totally independent and so it is possible to configure the
second Encoder. However, there are operational restrictions in the configuration
of Encoder 2 that depend on the algorithm and mode already selected for
Encoder 1. In chapter VI these restrictions are described in more detail.
If we select ENC from the main menu the following is displayed:
The ENCODER 2 option is only available if NET = ISDN.
IV.4.1 Configuration of Encoder 1:
The configuration of Encoder 1 (and Encoder 2 where available) is done in
stages, starting with the selection of an algorithm and following on with the
different parameters that relate to that particular algorithm. The ProntoNet menu
will always only display the options and parameters that are relevant to each
algorithm’s configuration. Additionally there are certain restrictions associated
