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 PortaNet that receives and accepts the call will automatically call back to the originating PortaNet and establish a reverse connection.
Page 106 “Prodys eXtended Real Time Protocol (PX-RTP) or SAP (according to the new standard for IP compatibility) will be used. The PortaNet transmitter cannot be in automatic encoding mode. To guarantee a constant delay all the units must synchronise their clocks.
Page 107: Ix.6.5 Multi-Unicast
Depending on the compression mode, up to 10 Tx connections will be available: • MPEG L2, L3 y AAC: Up to 10 Tx + 1 Rx. • PCM, G711, G722, APTX: Up to 3 Tx + 1 Rx. PortaNet User Manual 107 of 156...

(automatic audio synchronisation in all modes). • Prodys Real Time Protocol (P-RTP): This is a protocol based on UDP used for the transmission of audio. • Prodys eXtended Real Time Protocol (PX-RTP). This is a protocol based on UDP used for the transmission of multicast audio.

-Rx occupation: With average, maximum and minimum usage. Very low percentage of buffer occupation will cause audio interruptions and drop- outs. -Jitter: High jitter values will match with low buffer occupation. -Lost and disordered packets. This protocol is available from version 5.2.1 onwards. PortaNet User Manual 109 of 156...

Page 112 SIP Protocol manages by itself to negotiate the convenient communication details with the remote party. For Prodys’ former customers performing a call using SIP is much the same as using Prodys’ proprietary protocols given that the SIP configuration is set.
Page 113: Ix.8 Sap
When selecting SAP as communication protocol, only multicast calls will be available (point-to-multipoint). In addition, the user will have to indicate the announcement IP address and port on which the audio streaming is ‘announced’. PortaNet User Manual 113 of 156...
Page 114 Multicast Rx call types will be available. To launch an audio streaming over IP with SAP the user shall select Multicast Tx as call type from the dialing window, and type in the multicast IP address to send the audio to. PortaNet User Manual 114 of 156...

Page 116: Ix.9 Portanet Operating As An Isdn Codec
PortaNet operating as an ISDN codec The PortaNet as ISDN codec is very similar to the Pronto 3, therefore those users that are familiar with the Pronto 3 will find it easy to operate the PortaNet over ISDN. The most important points that a user must have in mind for this mode are as follows: 1.
Page 117: Ix.9.1 Establishing Isdn Calls
The CALL 1 key is for calling on Line 1 and the CALL 2 key is for calling on Line 2. On pressing the CALL 1 key the display prompts you to enter a number. Once the number is entered and the ENTER key is pressed, the PortaNet will go ahead and make the call.
Page 118: Ix.9.3 Restrictions In Isdn Communications
DUAL CODEC only allows two MONO communications. The display shows an error code to indicate the situation. b. PortaNet receives a call in the line 2 and detects that the audio is encoded in DUAL, JOINT STEREO or STEREO mode at 64 Kbps.
Page 119: Ix.10 How The Backup Mode Works
IX.10 How the backup mode works PortaNet when is configured as IP codec (NET = IP) can use the ISDN connection as backup line, that is, the ISDN will be an alternative communication line when the IP line is dropped.
Page 120: Ix.10.1.1 Portanet Master Operation
Backup Line 64 / 128 Kbps As we can see, the PortaNet configured as MASTER monitors the main line and it decides when the backup ISDN line must start to work. The PortaNet SLAVE only works in ISDN depending on if there is communication by it.
Page 121 (64 o 128 Kbps) when the unit starts working in backup mode. The PortaNet will try the connection as many times as it will be necessary until the connection will be established or until it decides that the main line has been recovered.
Page 122: Ix.10.1.2 Portanet Slave Operation
IX.10.1.2 PortaNet SLAVE operation If the PortaNet works as SLAVE, the entry or exit to the backup mode will be guided by different criterions than the defined ones in the MASTER mode. First of all, it is necessary that the Backup option be enabled.
Page 123 This option is only available from the PortaNet web Page: This option is very useful for an 64kbps ISDN link, where sending a stereo signal could involve a lack in the audio quality. Thus, encoding L+R signal, as a mono signal, will provide a much better audio quality.
Page 124: Portanet Blocks
PortaNet Blocks Knowing the different parts that comprise the PortaNet will help the user understand the various operational modes. The following chapter describes the different elements and their relationships. These sections are arranged in two different groups: Communications and audio.
Page 125: X.2 Audio Mic/Line Inputs
There are four MIC/LINE level audio inputs which can be assigned to either communication channel: PortaNet is equipped with four MIC/LINE level audio inputs, and each input can be configured to accept LINE or MIC level signals. There are two mixers, one for...

3. In IP, the compression mode for line 2 is fixed to G722 mode. Audio input diagram All the four inputs of the PortaNet are balanced XLR connector. Three of them are located on the front panel and the fourth one is on the rear panel. All of them can be configured to accept LINE or MIC levels, and to be phantom powered (48 volts.).
Page 127: Headphone Outputs
In other words, it will depend on whether the input is connected to line 1 or line 2. The audio sources for each headphone can be selected from the PortaNet web browser. At the same time, it is possible to define whether some of them will be attenuated depending on which line (program or talkback) its corresponding input t is connected.

1. A decisive factor in real time audio streaming is the ‘jitter’, or delay variation. To deal with the jitter in the connection, PRODYS provides a tool which allows the user to modify the size of the reception buffer, and so, to compensate for the jitter.
Page 143 2. The audio interruptions could be due to a reduction on the bandwidth in the IP connection. With the ‘Test Streaming’ tool from the web page, the user can measure the download and upload bandwidth between two Prodys IP Codecs. Once the user knows the available bandwidth, it is possible to select the proper bit rate for the compression mode.
Page 144 3. Lost and/or disordered packets might be the cause of audio interruptions. To obtain information about these parameters in real time, the Real Time Network Analyzers can be used.
