IX.5 About how the Decoder works and automatic searching
The PortaNet Decoder system doesn't need to be configured as it is totally
automatic. However, it is necessary to point out some aspects of how it works as
it depends on the format of incoming data. The PortaNet is able to synchronise
automatically to the following algorithms under the following conditions:
Algorithm
G711
G722
MPEG1,2 LII
MPEG1,2 LIII
MPEG2,4 AAC LC
MPEG 4 AAC LD
Mpeg AAC HE &
aptX
Linear Audio
Taking into account the previous table the user must also bear in mind the
following:
1. Over ISDN, it is only possible to set different encoding and decoding
algorithms independently, with those algorithms that support automatic
synchronising. For example, it is possible to transmit on G722 and receive on
MPEG Layer II.

IP Codec
(NET = IP)
aptX not with SIP/SAP

as IP protocols.
PCM
ISDN Codec
(NET = ISDN)
YES
The system detects
incoming calls such as
voice calls and
configures the Encoder
and Decoder to G711.
YES
Needs G722 encoded
audio since it is
synchronised by means
of statistical framework.
It does not work if
encoder is
configured to aptX ,
AAC HE or J52.
YES
It does not work if
encoder is
configured to aptX ,
AAC HE or J52.
YES
It is necessary that the
Encoder is also
configured to AAC or
