audio output. To avoid incorrect configuration there are therefore some
restrictions while working with the Prodys IP Family codec as a “DUAL CODEC”:
ƒ
If Encoder 1 is configured in any mode other than DUAL or STEREO/JSTEREO
the Encoder 2 option is disabled and the Prodys IP Family codec will not work
as a “DUAL CODEC”.
The Encoder 2 is not available also when NET = ISDN and bit rate = 128 Kbps.
ƒ
Encoder 2 can only be configured to work in MONO.
Further section shows how the Prodys IP Family codec operates as an ISDN
CODEC in detail. Restrictions are listed for the Encoder 1 in DUAL or STEREO
mode, as well as for receiving calls from other units that are working in any of
these modes.
V.4 Prodys IP Family codec working as a “Double CODEC” over
IP
A Prodys IP Family codec is a stereo signal capable codec. However the codec
provides a mean to split one stereo codec into two independent mono codecs .
This option is enabled at the
NET menu .
ƒ
<Simple Codec>: This is the setting by default. Stereo audio signals and
any compression algorithm might be enabled.
ƒ
<Double Codec>: This setting enables two independent mono codecs.
Following restrictions must be remarked:
d) Only mono signals can be encoded and decoded.
e) PCM and AAC HE streaming is not supported.
f) Apt-X and enhanced Apt-X are supported only at 16kHz
sampling frequency
