Prodys ProntoNet LC - VI.3 ProntoNetLC working as a “DUAL CODEC”

ProntoNetLC User Manual 113
VI.3 ProntoNetLC working as a “DUAL CODEC” over ISDN
When we select ISDN as the communications interface, it is possible to establish
two totally independent MONO connections for each 64 Kbps B Channel. This
means that for each channel or line of communication (Line 1 or Line 2 as seen
by the ProntoNetLC) it is possible to send an audio signal encoded with any of
the available codec algorithms. The menu offers the option to configure Encoder
1 and Encoder 2 separately. However, the user must remember that in this
mode it is only possible to work with MONO signals on each channel, given that
ProntoNetLC has only one stereo audio input and one stereo audio output. To
avoid incorrect configuration there are therefore certain restrictions while
working with the ProntoNetLC as a “DUAL CODEC”:
 If Encoder 1 is configured in any mode other than DUAL or STEREO/JSTEREO
the Encoder 2 option is disabled and the ProntoNetLC will not work as a
“DUAL CODEC”.
The Encoder 2 is not available also when NET = ISDN and bit rate = 128 Kbps.
 Encoder 2 can only be configured to work in MONO.
Section VI.9 looks at how the ProntoNetLC operates as a ISDN CODEC in more
detail, and it will detail other restrictions that need consideration when we
configure Encoder 1 in DUAL or STEREO modes, or when it receives calls from
other units that are working in any of these modes.
VI.4 ProntoNetLC working as a “DUAL CODEC” over IP
31
There are two different operation modes: SIMPLE and DOUBLE mode
32
. In
SIMPLE mode, the unit will work as usual, that means, it cannot establish two
independent communications via IP. In DOUBLE mode, the unit can establish
two independent communications via IP.
In DOUBLE mode over IP, the following restrictions will be applied:
1.- Encoder 1 and Encoder 2 can only be set in MONO.
2.- Encoger 2 (assigned to line 2) can only be set in G722.
This configuration can be set both from the menu and from the Web Page.
31
Operation mode only available when selecting Prodys Proprietary Protocols over IP.
32
From version 4.5.0 onwards.
