General specifications

PortaNet is the first really portable audio codec which provides real time audio communications over IP networks. In addition, it comes fitted with an 1-BRI ISDN interface, which allows ISDN connectivity at those places where IP is not available. PortaNet, as a member of the Prodys IP audio codec family, includes all the features of the ProntoNet, but adds some important enhancements in the audio interfaces and operationally for portable use.

These are the PortaNet most important features:

 Analog Audio: PortaNet incorporates a mixer with four MIC/LINE

level configurable audio inputs and an extra line level input that can be mixed to the headphone outputs to provide the international sound to the commentators. It also includes three headphone outputs and two line level analog balanced audio outputs. All the outputs can be configured by the user to suit the audio signal to be carried, to adapt to the needs of different applications.

 Compression algorithms: PortaNet is equipped with the widest

range of compression algorithms without any additional cost: G711, G722, PCM, MPEG1,2 Layer II, Mpeg 1,2 Layer III, MPEG 2,4 AAC LC, MPEG4 AAC LD, MPEG4 AAC HE, Standard and Enhanced apt-X™.

 Communications: IP and ISDN connectivity. With PortaNet it is

possible to establish two independent connections, one for program and the other for coordination.

 Power supply: Desk Top AC/DC Power Converter and an optional

battery which provides 3 hours of autonomy. The battery can be charged on the system and its status can be monitored on the screen.

 Auxiliary data: PortaNet includes a serial port (RS232) and a GPIO

port with 2 inputs and 2 outputs. The auxiliary data can be sent/received along with the audio for remote control/signalling.

 Control and monitoring: The unit can be configured from its front

panel and from its embedded web page. All the controls are configurable remotely. The keypad can be controlled and also blocked from the web page for security reasons.

 Small and lightweight: its weight is about 2 kg. and its dimensions

are: 70 x 285 x 243 mm.

When the unit is starting, the Power LED will be blinking green.

PortaNet User Manual 13 of 156

III.1.2 The front panel and its connectors

In the front panel there are two areas: Audio inputs and Headphone outputs. Because of space restrictions the Auxiliary output level control is also there.

There is an additional fourth input in the rear panel. This input doesn’t have an associated headphone output.

MIC/LINE Audio inputs: There are four MIC/LINE audio inputs. Each audio input

includes a switch to select MIC or LINE level, and another one for selecting whether to supply 48 volts. phantom power to the MIC.

line/mic switch:

 When this switch is in the UP position, the line level input is

selected (maximum input level +20 dBu).

 When this switch is in the DOWN position, this input is

configured to work as a MIC level input.

ph swtich(48 volts. Phantom powered):

 When this switch is in the UP position (OFF), this option is

disabled.

 When this switch is in the down position (ON), this option is

enabled.

Headphone outputs: There are three headphone outputs, each one related to

its corresponding audio input. Signals present on the headphone audio outputs will be dependent on the configuration of the audio headphone matrix available in the PortaNet web browser. More information about it in next chapter about PortaNet’s input and outputs. There are audio level controls for each output and for each ear.

Line level balanced auxiliary audio output: Along with the three headphone

outputs, there is a fourth output called ‘aux’. This audio output is totally independent from the headphone outputs, and it is placed together with these only for space saving reasons. This output is a balanced line level output, with a

PortaNet User Manual 14 of 156

maximum level of +20 dBu. This output is user configurable; that means that it is possible to define which audio signals will be present in this output.

Further information about audio output configuration can be obtained from chapter 5 - PortaNet Blocks.

III.1.3 Rear Panel

The rest of connections are located on the rear panel:

III.1.3.1 Fourth MIC/LINE audio input (in 4).

The same as the inputs from the front panel, it can be configured as LINE or MIC level, and it has the possibility to be phantom powered (48 volts.) However, it doesn’t have a headphone output related. For this purpose, the ‘aux’ output might be used.

III.1.3.1.1 LINE level input (International Sound Input – Int. in)

This is an additional line level input which can be mixed with the headphone outputs to provide the international sound to the commentators.

III.1.3.2 Second auxiliary line level output.

Called REC output, this output can carry the program line signal, the return from the program line or the sum of both signals. This is a balanced XLR connector.

Further information about audio output configuration can be obtained from chapter 5 - PortaNet Blocks.

PortaNet User Manual 15 of 156

III.1.3.3 Auxiliary data: GPIO and RS232 ports.

The GPIO port on a DB9 connector allows remote control/signalling by means of remote contact closures. There are two ground contact inputs and two relay outputs.

Another DB9 connector at the rear panel provides an RS232 port for sending/receiving auxiliary data along with the encoded audio for IP and ISDN communications.

Over ISDN, the auxiliary data and GPIO information will be only available in those compression algorithms which support ancillary data along with the encoded audio, and when this option is enabled.

Over ISDN, it is possible to choose between ProntoNet format and Pronto2/3 format (in which the GPIOs information cannot be sent). To be backward compatible with ISDN Pronto2/3 Prodys devices, select Pronto2/3 format.

When selecting IP as communication interface, the auxiliary data can be sent via a different path, different from the audio one. This method has 3 big advantages: less delay independent from the audio codification delay; the possibility to send/receive auxiliary data regardless of the compression mode used for the audio communication; and the possibility to send/receive the User bit of the AES/EBU frame. The drawback is that the audio and data delay won’t be the same.

III.1.3.4 Ethernet port – the LAN Connector

The LAN socket is an standard 100Base-Tx (10/100 Mbps) Ethernet connection that takes a RJ45 plug. Through this Ethernet port it is possible to transmit and receive audio, as well as manage the equipment. Next to the socket there are three LEDs that indicate different states for the connection and these are very useful in problem-solving situations.

LAN LED’s:

Receiving Data.

Further information can be obtained in the chapter - XIV - Connectors.

From the web interface and the front panel menu it is possible to set the speed and duplex configuration to the following values: AUTO, 10HD, 10FD, 100HD, 100FD1.

III.1.3.5 ISDN Port

The PortaNet incorporates an ISDN terminal adapter that allows connection to a basic rate ISDN line (2B+D). It supports different ISDN protocols (EURO_ISDN, DMS100, AT&T 5ESS and NAT1). There is one RJ45 connector for connecting to an S/T interface S/T (S0).

There is available a special version with U ISDN interface.

III.1.3.6 Power supply

PortaNet comes supplied with a desk top AC/DC converter (16 volts. output) to be connected to the power connector located at the rear panel. The power converter works with an AC input range of 100 to 240 VAC, 50 to 60 Hz. The power switch is located just below the power connector. In addition, there is also available an optional custom

battery pack. Whenever the external power converter is connected, the power is supplied from it, and the battery will be charged when necessary. When the external power converter is unplugged from the unit, the battery will take over.

This option is available from version 5.2.1 onwards.

PortaNet User Manual 17 of 156

The power LED on the upper panel informs about the status of the battery and the power supply. These are the possible status for this led:

-GREEN: The external power converter is powering the unit. The battery is not connected.

-BLINKING ORANGE: The external power converter is powering the unit. The battery is connected and it is being charged on the system.

-ORANGE: The external power converter is not powering the unit. The battery is connected and powering the unit.

-BLINKING RED: The external power converter is not powering the unit. The battery is connected and powering the unit, but it is about to run out (about 20 minutes / 10% of battery capacity).

Once the unit is switched on, the boot sequence will start. This sequence will take about 50 seconds to finish, when the screen will display the status display. When the unit is starting, the Power LED will be blinking green.

PortaNet audio inputs

IV.1 Location

There are four MIC/LINE level inputs, switchable between LINE and MIC level. Three of them are located on the front panel, and the fourth one is on the rear panel. Moreover, there is an additional line level input located on the rear panel which can be mixed to the headphone outputs.

IV.2 Technical specifications

IV.2.1 MIC/LINE level inputs

 All the MIC/LINE level inputs are transformer balanced on a XLR female

connector. These inputs are switchable between MIC and LINE levels by means of a switch placed on the right side of the input connector.

 It is possible to supply phantom power (48 volts.) to each input. There is

a switch on the left side of the input connector for this purpose.

 When the audio inputs are configured as MIC level inputs, sensibility

range is –60 to –25 dBu.

When phantom power is enabled, the whole gain is decreased by 15 dB to compensate for the the higher output of condenser MICs. Thus, the gain range will go from –45 to –10 dBu.

 When the inputs are configured as LINE level inputs, the maximum input

level will be +20 dBu.

 Each input level can be adjusted independently.

IV.2.2 International Sound LINE level input.

 Electronically balanced on a XLR female connector.  Maximum input level is +20 dBu

PortaNet User Manual 19 of 156

IV.3 Audio Level Controls

Each audio input can be adjusted independently. The audio level control can be made locally from the knobs or remotely by using the PortaNet web browser.

Once the audio input gain setting has been selected to be controlled by remote control, the PortaNet reminds this effect on its display upon any attempt to increase or decrease the audio gains locally by means of the audio control knobs.

The International Sound Input level can be adjusted only remotely.

IV.4 Audio input configuration

IV.4.1 ON keys

Each audio input has a key to enable/disable it. When an input is enabled, it will contribute to the audio sent through the program line (line 1). The corresponding LED will light on GREEN, indicating that the input is enabled and going through the line 1.

IV.4.2 TB Keys

PortaNet supports two independent communications via IP or ISDN. Thus, we can establish one connection for the main program, and another one for coordination, or TalkBack program. Each input can be configured to be added to the audio contribution on line 1 or line 2 by means of the ‘TB’ and ‘ON’ keys located on the top surface.

 When an input is connected to line 2 or TalkBack program (pressing the

Tb key) it is disconnected from the program line (line 1). The corresponding LED will light on RED.

 When an input is connected to line 1 or program (pressing the ON key)

it is disconnected from the TalkBack line (line 2). The corresponding LED will light on GREEN.

 When the input is disabled, the led is off.

PortaNet User Manual 20 of 156

When one input leaves the TalkBack line (line 2), this input is disabled for security reasons. This way, this input cannot enter the program line unintentionally. However, it is possible to change this operation mode from the web page. When the Recover Last Mode is selected, the input will recover its previous status when it leaves the TalkBack line.

PortaNet audio Outputs

There are three headphone outputs and two general purpose balanced audio outputs (line level).

V.1 Location

 The three headphone outputs are located together on the front panel.  One of the balanced audio outputs is located on the front panel, called

‘aux’, and the other is on the rear panel, and it is called ‘REC’.

V.2 Headphone outputs.

V.2.1 Technical specifications

 6.3mm Jack connector  Headphone impedance range: 300 – 2K ohms.  Output Impedance < 25 ohms.  Bandwidth 20Hz-20kHz (1dB).  Maximum output level: 6dBu (8 mW) on 300 ohms.  THD+N < 0.01% @ 1kHz.  SNR < 95 dB.  Independent audio sources (local o return) for left and right.  Independent level adjustment for each output.

V.2.2 Operation mode – Headphones Matrix

 The audio sources for the headphones can be selected from the PortaNet

web browser. At the same time, it is possible to define if some of them will be attenuated depending on which line (program or talkback) its corresponding input t is connected.

 The audio sources that can be selected are: Programa, Cue, Talkback Tx,

Talkback Rx and International Sound.

 Program, Cue and International Sound can be selected in each ear

headphone independently.

to the program line or to the talkback line. Also, it allows the user to select whether the signal will be controlled from the audio input keypad.

V.2.2.1 Attenuation when the MIC/LINE level input goes to Talkback or

Program

It is possible to define an automatic attenuation on signals that feed the headphone outputs when the corresponding inputs go from Program to Talkback or vice versa. The attenuation will be carried out according to the following critera:

Program, Cue or International Sound can be attenuated when the corresponding input is connected to the Talkback channel. It is possible to define an independent attenuation level for either of them.

The same thing can be done regarding Talkback Tx and Talkback Rx, that is, either signal can be attenuated when the corresponding input goes to program.

V.2.2.2 Enable from TB Key

“Enable from Tb Key” is an additional option that only is available for Talback Tx and Talkback Rx. When it is enabled, the corresponding signal will be sent to the headphone outputs only when the corresponding input has been connected to the Talkback channel, that is when its corresponding Tb key has been pressed.

To create an audio preset, open the Presets window in the Configuration menu and the click on the “New” button. A new pop up window makes possible to save the current settings and any further modification and to store with the Preset label of your choice (by default “Preset # “).

Once the name of the new preset has been added to the list, it is necessary to press Ok or Apply in order for the audio preset to be stored.

The new audio preset will be created with the current audio configuration.

PortaNet User Manual 30 of 156

In order to check or modify an audio preset, just select the configuration of your choice from the list and press the Modify button2. The “Preset name” indicates the label of the configuration under your focus. Any changes along the “AUDIO INPUT”, “AUDIO OUTPUT” or “AUDIO MISC” menus would be applicable to the selected preset as soon as the OK button is pressed. If instead the Cancel button has been selected then the original preset configuration is kept.

Keep in mind that the edition of any preset configuration will not disturb the current audio settings in operation.

Note: While the current audio configuration matches one of the stored Presets, this will be indicated on the second line of the Preset Configuration panel as “Current Preset: <…..>”. Any mismatch between the Preset Configurations and the actual audio configuration forces the indication “Current Preset: <none>”.

VI.3 Loading a preset

Once a preset has been selected, its configuration can be invoked as active or current by clicking on the “Load” button. The new configuration can be checked by moving through the different audio configuration menus. Until the “Apply” or “Ok” buttons are not pressed, the new audio configuration will not take effect.

VII.4 Configuring the communication interface

Before making any connection it is advisable to check that all the communication interfaces are configured properly. The following is a quick guide to check this configuration and how to modify it when necessary.

VII.4.1 Configuring the ISDN Terminal adapter

The ISDN Terminal adapter carries out all the signalling protocol in an ISDN communication. The parameters to configure it are the following:

a. Communication protocol  Check that the selected protocol is

compatible with the line provided by your Telco. Most countries except the USA now use EISDN.

C O N F P O R T S M E N U

S E T I S D N P O R T

S E T I S D N N E T

b. Local number or ‘LNUM’  An abbreviation for ‘Local Number’. With

this option it is possible to assign a different number to each of the lines available on the basic rate ISDN. In this way we can automatically map incoming calls to each line, as each line will only respond to calls made to this local number. When the local number is programmed the unit only detects as an incoming call those calls that are made to the local number all other calls are not recognised.

S E T I S D N P O R T

S E T I S D N L I N E 1

{ L N U M } C N U M S P I D A N S

c. CNUM  An abbreviation for ‘Calling Number’. This option allows you to

program up to a maximum of three numbers that will work as incoming call filters. When the CNUM option is activated, the PortaNet will respond automatically only to calls made from these CNUM numbers. It is possible to program each line separately.

PortaNet User Manual 34 of 156

{ L A N } I S D N R S 2 3 2

{ I P } D H C P E T H P O R T S

d. SPID  When you are using NAT1 or DMS100 you must enter the correct

Service Profile ID (SPID) numbers for the ISDN BRI circuit.

e. ANS  Automatic or manual response: When automatic response is

selected, the unit will connect automatically to an incoming call, always doing so when there is no restriction imposed by the local number or other such call filters. In manual mode, the incoming calls are indicated on-screen and the user simply presses the corresponding CALL key to go ahead and connect that line.

VII.4.2 Configuring the LAN port

Before making a connection over any IP network it is necessary to configure the IP addressing parameters: IP address, netmask and gateway. PortaNet allows the assignment of the IP parameters either manually or by DHCP.

 Manually  User must enter the following IP parameters manually:

1. IP address.

2. Mask.

3. Gateway IP address

C O N F P O R T S M E N U

L A N C O N F I G

 Automatically  The unit gets the configuration automatically from a

DHCP Server when starting.

VII.5 Checking the communication interfaces

Once the interface has been properly configured, the user can make some tests to confirm that the unit is ready to work. An easy way to check that everything is working fine is to make a ‘loop’ call, by calling our own unit.

VII.6 Connecting PortaNet to the line

Either using ISDN or IP, when plugging the link line cable into the unit, the display should indicate this with the word “IDLE” on the screen.

L 1 : I D L E ( 0 ) I S D N

L 2 : I D L E ( 0 )

PortaNet User Manual 35 of 156

When no link line is detected on the communication interface, the word “DOWN” is displayed.

L 1 : D O W N I S D N

L 2 : D O W N

VII.7 Audio checking

PortaNet is equipped with a Vu meter on the top panel, and furthermore it offers the possibility to get audio level information from the display by pressing the INF key in the menu keypad. Let’s take a look at both types of information:

The VU meter on the top panel measures the audio level just before the compressor/limiter. This level corresponds to the sum of all the inputs which contribute to the program line (line 1), that means, all those inputs whose led is on GREEN. This Vu meter comprises several green leds and a red overload led.

The audio levels obtained from the display with the INF key are digital domain measurements. The input levels are measured before the compression and the output levels are obtained after de decoding process, as can be seen from the following diagrams:

VII.8 Selecting the compression algorithm

The ENC option in the menu allows the user to change the encoding mode. The following points must be taken into account when configuring the encoder:

1. The encoder of line 2 or TalkBack line cannot be configured in any mode other than G722 when IP is the selected network. Over ISDN there are no restrictions regarding the available compression modes for this encoder.

2. The AUTO mode causes the encoder to adopt the configuration detected by the corresponding decoder.

3. The available options will depend on the selected network (IP or ISDN) due to some crucial differences such as the line bandwidth.

When selecting the ENC option on the main menu the following screen appears:

The different options for the Encoder 1 are as follows:

 AUT : Automatic mode.  PCM : Linear audio.  G711.  G722.  MPL2 : MPEG 1,2 Layer II.  MPL3 : MPEG 1,2 Layer III.  AAC2LC: AAC MPEG 2 Low Complexity.  AAC4LC: AAC MPEG 4 Low Complexity.  AAC4LD: AAC MPEG 4 Low Delay.  AAC4HE: AAC MPEG 4 High Efficiency.  Apt-XTM : Standard and Enhanced

VII.9 Decoder operation

The Decoder is totally automatic, except when working over ISDN and receiving J52 and aptX The Decoder of line 2 or TalkBack line is fixed in G722 when the IP interface is selected.

TM.

VII.10 Calling from PortaNet

PortaNet can establish connections both via ISDN and IP networks. The procedure is very similar and can be carried out from the web page or the main menu. Let’s see how to establish a call from the top surface control keypad.

PortaNet User Manual 37 of 156

VII.10.1 CALL1, CALL2 and Phone Book keys

The CALL1 and CALL2 keys give the user access to the call control menu for line 1 and line 2 respectively. The Phone Book key is used for establishing communications using a configuration saved in the Address Book. This book can store both ISDN and IP numbers. Also, each entry of the book can store the compression mode to be used when connecting to the stored number. It is worth mentioning that the encoder of line 2 or TalkBack line cannot be configured when working over IP, and that it is fixed in G722 mode and any other algorithm is discarded.

The fundamental role of these keys is the initiation and termination of a connection. Note that the keys have different functions depending on the communication line status at any given moment. Additionally, the display will also show different information depending on the type of NET selected - IP, or ISDN. Depending on the line’s status, CALL 1 and CALL 2 will function in the following way:

 With the line disconnected:

a) Initiation of a communication: Pressing CALL 1 or CALL 2 will

access the call initiation menu. Depending on the type of NET selected (IP or ISDN) the dialog that you will see will vary. (Note that, CALL 2 only works when PortaNet works as a DUAL codec3).

b) Connecting to an incoming call: if the PortaNet is pre-configured

to manual answering, the CALL 1 or CALL 2 keys will connect the line when an incoming call is detected on the respective lines.

 With a line connected: There are two different functions:

a) A short press will display on-screen the number or IP address of

the current connection.

b) A long press (over 1 second) will disconnect the associated line.

It is possible to program a number of call retries from the PortaNet web page.

DUAL codec: PortaNet is able to operate as a DUAL codec over ISDN and over IP (when

configured in ‘DOUBLE’ mode).

PortaNet User Manual 38 of 156

VII.10.1.1 Establishing a call when PortaNet is configured as an IP

Unicast/Multicast codec

Pressing CALL 1 the screen will display the following:

L A N L 1 M O D E

{ M U L T I C A S T } U N I C A S T

The user must select which kind of communication will be used:

 Unicast Bidirectional  This is a bidirectional point to point connection,

that is, both ends will transmit and receive audio simultaneously. It will be necessary to check the upload and download bandwidth on the link.

 Unicast Unidirectional Tx  This is a unidirectional point to point

communication where only the end which makes the call will send audio.

 Unicast Unidirectional Rx  This is a unidirectional point to point

communication, where the calling end will be the receiver.

 Multicast Tx  This is point to multipoint communication in which the

calling end will join a multicast group as a transmitter.

 Multicast Rx  This is point to multipoint communication in which the

calling end will join a multicast group as a receiver.

Next, depending on the selected option will show:

Pressing CALL 1 the screen will display the following:

M U L T I U N I C A S T C A L L { G r o u p R e d i a l }

Group Redial is the only option available when calling from the front panel. This option will try to re-establish all previous connections, both Tx and Rx.

CALL 2 key is not available under Multi-Unicast mode.

This option is available from version 5.2.1 onwards.

PortaNet User Manual 40 of 156

VII.11 Calling from the Phone Book

This key directly accesses the internal Address Book. By pressing this key we can view and connect to entries in the Address Book (NOTE: To edit or modify entries go to the BOOK option in the main menu). For making connections however, the BOOK key works like this:

Pressing BOOK you enter the Address Book index:

Use the left and right navigation keys to go through the different entries in the Address Book index. By pressing OK we select the item that is on-screen. Now the screen shows the number/numbers to call, or the IP addresses, depending on which ones have been saved.

Pressing OK again will process this information, that is, the PortaNet will configure the Encoder according to the BOOK entry and make the connection over ISDN or IP. By pressing the right arrow key instead of the OK one, the unit will display the saved encoding mode.

L 1 : 1 2 3 4 5 6 7 8 9 0

L 2 : 1 2 3 4 5 6 7 8 9 0

PortaNet User Manual 41 of 156

When you press the BOOK key you will only be shown those entries that are relevant to the NET that is currently activated. So when NET = ISDN, you will only be able to browse previously stored ISDN entries, just as when NET = IP you will only be able to select from relevant IP addresses.

E 1 : M P L 3 - 1 2 8 - M N -

VII.12 Incoming calls

The incoming calls can be connected on line 1 or line 2. It is worth mentioning here that each line has a different application and, for example, over IP, there are different configuration options (line 2 only encodes G722). Line 1 will be the main program and line 2 the coordination or TalkBack program.

Next follows some recommendations to avoid confusion when controlling the lines:

VII.12.1 Receiving ISDN calls

Compatibility: it is compatible with any ISDN audio codec with the same compression modes.

Compression algorithms: There are no restrictions regarding the available compression modes in any line. Encoder and decoder can work in different modes independently.

Automatic and manual answer: Incoming calls can be answered automatically or manually depending on the menu option ‘ANS’. If the ‘ANS’ mode is set to manual, the corresponding CALL key must be pressed to accept the call and connect to it.

- Automatic answer  The call is picked up automatically.

- Manual answer  In this mode, the unit will warn about the incoming call

by blinking the LED of the corresponding line. To pick up the call, press the corresponding CALL key.

Mapping Incoming calls: With the LNUM (local number) option it is possible to assign a different number to each of the lines available on the basic rate ISDN interface. In this way we can automatically map incoming calls to each line, and each line will only respond to those calls which were made to this local number. When the local number is programmed the unit only detects as an incoming call

PortaNet User Manual 42 of 156

those calls that are made to the local number - all other calls are discarded. Thus, the user can control which calls will be connected on program line (line 1), and which ones on the coordination line (line 2).

When there is only one number available for both channels, the first call will be connected on line 1 and the second one on line 2. Thus, before making connections for establishing the TalkBack channel, make sure that the program line has been already connected.

VII.12.2 Incoming calls via IP

Compatibility: PortaNet supports a proprietary IP streaming protocol, only compatible with Prodys IP audio codecs. In addition, support for industrystandard algorithms is provided under the ‘Streaming Protocol’ tab in the Configuration window of PortaNet web page. A preliminary version of all protocols defined as ‘mandatory’ by the EBU group in their N/ACIP (Audio Contribution Over IP) project is supported. This project defines the standard to achieve interoperability between audio codecs over IP.

Available compression modes: Line two can only be configured to G722 (encoder and decoder). Line 1 can be configured to any compression mode. The encoder and the decoder of line 1 can work in different modes.

Automatic answer: The answer mode is always automatic, so the call is answered automatically.

Incoming call mapping: it is not possible to map the incoming calls to a line. And the following rules apply:

PortaNet User Manual 43 of 156

 All the calls made from line 1 in ProntoNet or PortaNet will be received

Capít

through line 1.

 All the calls made from line 2 in ProntoNet or PortaNet will be received

through line 2.

PortaNet User Manual 44 of 156

PortaNet remote control

PortaNet can be controlled remotely by using an Internet Explorer web browser connected through the LAN port. The computer can be locally connected directly via a crossover CAT-5 cable, or remotely from a computer connected to the LAN. To access the PortaNet using Internet Explorer, enter the IP address of the unit in the address bar. Keep in mind that the PortaNet factory IP address is

192.168.100.100 and it could be necessary to modify the network configuration of the computer on which the web browser is running.

Installation Requirements

1.- Pentium 166 or higher.

2.- 64MB RAM minimum.

3.- Operating Systems:

Microsoft Windows XP, Microsoft Windows 2000,

PortaNet User Manual 45 of 156

The first time the user accesses the PortaNet web page, an OCX file has to be downloaded and installed on the computer. Microsoft Internet Explorer can be

configured to block OCX objects installation and/or execution. So, depending on

the configuration of the web browser, a message like the following might appear when first accessing the PortaNet web page:

Go to Internet Options in IExplorer, click on ‘Security’ tab, and set ‘prompt’ when downloading ActiveX signed and unsigned controls at Local and Internet zones.

PortaNet User Manual 46 of 156

Each firmware version might have a different OCX file, so the new OCX should be installed as it is done for the first access to the web page of the unit. If the unit was upgraded and, depending on the ‘cache’ configuration of the Internet explorer, there might be problems when accessing the web page, given that the old web page might be offered by the browser instead of the real one, which should be installed to replace the old one. In this case, a message indicating ‘Incorrect Versions’ will appear as soon as the user click on ‘Control’ or ‘Monitor’ on the login page. Click on F5 to skip the cache entries, and access to the ‘real’ web page. Even after pressing F5 and, depending on the IExplrorer configuration and/or version, this situation might continue. In that case, go to Internet Options in IExplorer, click on ‘General’ tab, and delete temporary files

MORE ABOUT THE PORTANET PORTS

Changing Portanet Ports: The PortaNet configuration menu allows the user to configure which ports the unit will use for its TCP/UDP/IP communications from the web page.

There are two different groups:

 Web Server Port: By default, it is TCP port 80. This is the internal web server

port.

PortaNet User Manual 50 of 156

 Base Port: By default, it is 50011 for TCP and UDP ports. This is the first port

of the range of ports used by the unit. From this base port on, up to 30 ports should opened/forwarded. That is, if the base port is set to 50011, the range of ports goes from 50011 to 50041, both for UDP and TCP, should be opened/forwarded in the corresponding router/firewall (when required).

IMPORTANT

The following should be taken into consideration when changing the web port:

 To access the web page of the unit, the new port has to be indicated in

5. Mask.

6. Gateway IP address

PortaNet User Manual 51 of 156

 Automatically  Check “Obtain an IP address automatically” option to get

the configuration automatically from a DHCP Server.

By setting DHCP, the unit will receive its IP parameters when starting. These IP settings might be different from time to time, that is why PortaNet supports RIP2 protocol. This protocol allows the user to set an ‘internal’ IP address, in order that the unit can be identified regardless of the IP settings provided by the DHCP server.

• DNS support:

By specifying the IP address of a DNS Server, the user can make calls to ‘names’ instead of IP addresses. This new feature is available in any place where an IP address has to be entered. For example: the dial window, the phone book, SNTP IP server address…This is the DNS configuration windows:

port of the range of ports used by the unit. From this base port, up to 30 ports should opened/forwarded. That is, if the base port is set to 50011, the range of ports goes from 50011 to 50041, both for UDP and TCP, should be opened/forwarded in the corresponding router/firewall (when required).

The following things should be taken into consideration when changing the base port:

1. To access the web page of the unit, the new port has to be indicated in the http address bar of the web browser after the IP address, separated by a colon:

http://<IP>:<Web Port> Example: 192.168.0.10:8080

2. To log into the unit, click on the advance features button of the login window:

and specify the base port which we want to connect to:

3. When establishing a call, the new base port must be entered after the IP address, separated by a colon. Example: When calling to a unit which IP address is 192.168.1.2, and base port 40011, the following call destination should be entered into the ‘Dial’ window: 192.168.1.2:40011.

4. When establishing a bidirectional call with Prodys IP codecs, two connections are made automatically, one for each direction. For the

VIII.2.2 System Configuration

Grouped here are functions that affect the general operation of the unit.

 Loop: This sets up an Encoder-Decoder loop. Its purpose is to help the user

to find problems with audio connections. The loop takes place in accordance with the configuration available at that moment.

 PLL: This is a special option that allows you to select the PLL reference clock

when NET = IP.

 Redial:It is possible to configure a number of redials. The PortaNet will try

the connection in the following cases:

1.- The unit is trying the connection for the first time.

2.- The unit was connected and lost the connection because the line dropped or the line was disconnected from the other end.

 Keypad: This option allows the user to lock automatically the frontal panel

keypad. Automatic means that the keypad is locked a short while (around 1 minute) after you just press a key. It is possible to unlock from the keypad by pressing Ok and then *.

This option is available from version 3.3.1.

normal circumstances the indicator should be in the middle Green area.

 Reboot System: A new option to reset remotely a unit was included in the

SYS configuration menu.

 PortaNet external protocol: The PortaNet Software Development Kit

provides a tool to manage the PortaNet units from external applications or devices different than ProdysControl. In this manner, it is possible to customize the control of the units and to integrate them in a global management system.

The protocol is based on which can be managed through two different communication ports: the LAN port and the RS232 B port. For more information, please read ProntoNet SDK User’s Manual.

 IP Codec Mode: There are two different operation modes: SIMPLE and

DOUBLE mode. In SIMPLE mode, the unit will 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:

PortaNet User Manual 63 of 156

1.- Encoder 1 and Encoder 2 can only be set in MONO.

2.- Encoder 2 (assigned to line 2) can only be set in G722.

 Buzzer: It is possible to enable/disable the buzzer from this option. The

buffer warns the user about incoming calls when the unit is configured as an ISDN codec and the answer mode is set to manual.

VIII.2.2.1 TimeDate

This option allows the user to synchronize time and date by using SNTP protocol (Simple Network Time Protocol). SNTP operates always in the client-server model and for this reason, PortaNet can work as SNTP server or SNTP client.

VIII.2.2.2 Password

Whenever the web browser is started, it is necessary to enter a security password. This is the dialog to program it.

PortaNet User Manual 64 of 156

VIII.2.2.3 Aux Data

 RS232: There is one RS232 port for use as auxiliary data port. This port

allows the transmission and reception of data along with the encoded audio. When the option is checked, the corresponding decoder will allow the reception of ancillary data.

When selecting IP as communication interface, the auxiliary data can be sent via a different path, different from the audio one (the auxiliary data are embedded in the audio frames). This method has 3 big advantages: less delay independent from the audio codification delay; the possibility to send/receive auxiliary data regardless of the compression mode used for the audio communication; and the possibility to send/receive the User bit of the AES/EBU frame. The drawback is that the audio and data delay won’t be the same.

 GPO: Under ‘transparent’ configuration, the state of the input will be present

in its homologous output in the device connected at the other end. Since there is only one GPO connector, user must select whether to select GPO information coming from Decoder1 or from Decoder2, or none.

VIII.2.2.4 Software Versions

VIII.2.2.5 Alarms

From this option it is possible to select the IP address where the SNMP traps will be sent. An SNMP manager located at this IP address will receive and process the information according to the SNMP protocol. These SNMP traps will notify alarm information, that is, an SNMP trap will be sent when an alarm is activated or deactivated, with the time and type of alarm. For this to happen, alarms have to be enabled (see chapter VIII.8 Alarms). PortaNet can be fully monitored though SNMP protocol. It is also possible to notify alarm events via email. The user can send alarm information to several email addresses at the same time.

The proceeding to edit a phone book index is as follows:

1. To select one index by clicking on its area.

2. To select ISDN numbers or IP Address depending on which network will be used. Only it is possible to select one of them.

3. To enter the ISDN number/numbers or the IP address according to the before selection.

4. To configure the encoder is optional. In case of that it is not entered, the unit will proceed to call in the current encoder configuration.

PortaNet User Manual 67 of 156

It is possible to Export / Import the Book in XML format. It is also possible to create an html report allowing to preview and print.

The audio compression mode is restored to that one prior to the connection. This allows the user to change the compression mode during the connection, or to make calls through the book entries with compression modes different from the former one.

VIII.2.2.8 Scheduler

The Scheduler allows the user to program calls to be made automatically. For more information read chapter VIII.6 - Scheduler.

VIII.2.3 Streaming

Streaming parameters objectives:

-Provide a ‘test’ tool to check in real time the bandwidth, delay and jitter of

the IP connection between two PortaNets.

-To allow adjustment of the various transmission and reception parameters to

optimize the unit to provide the best quality real-time audio streaming for a particular network connection.

These tools are grouped in the following manner:

1.- Protocol.

2.- Transmission parameters.

3.- Reception parameters.

4.- Test tool.

PortaNet User Manual 69 of 156

VIII.2.3.1 Protocol

Streaming Protocol: This option allows the user to configure the streaming protocol to use for transmission over IP. There are five choices;

• Proprietary: Prodys proprietary IP streaming protocol.

• Proprietary v2: Prodys proprietary IP streaming protocol version 2.

• SIP: SIP is a signaling protocol for creating, modifying, and terminating

sessions with one or more participants. For more information please check the proper section of this document.

• SAP: SAP is a protocol for broadcasting multicast session information.

• CCS NetStart/AudioStar.

VIII.2.3.2 Tx

Audio: This option allows the user to configure the audio transmission parameter (TBP: Time between packets) and to know in advance, the required bandwidth and delay of the connection.

IP: This option allows the user to configure some IP header fields to carry out QoS.

PortaNet User Manual 70 of 156

VIII.2.3.2.1 Audio

The ‘Time Between Packets’ (TBP) parameter is directly related with the packet size and therefore with the occupied bandwidth (overhead) and delay. Therefore, the appropriate value for this parameter is a trade off between delay and bandwidth.

In order to achieve the minimum delay between encoder and decoder it is necessary that the transmission time between packets is minimum as well. However, the greater the TBP, the less bandwidth is required (less overhead), but the more delay there will be in the connection. Otherwise, the smaller the TBP, the smaller the packet size, and the greater the overhead, due to the IP headers in the packets. With this tool, the user can know beforehand the required bandwidth, overhead, packet size and delay for the current compression mode and TBP value.

When the packet size needs to be fragmented, keep in mind that the overhead changes for that reason. When it happens it is indicated as follows:

PortaNet User Manual 71 of 156

VIII.2.3.2.2 IP:

This option allows the user to configure some IP header fields to carry out QoS.

- Streaming Packets Quality of Service: This option allows the user to configure the value in the ToS field in the IP header. This field can be used to carry out QoS in the network.

- Streaming packets Time To Live: Configure the Time To Live parameter.

PortaNet User Manual 72 of 156

VIII.2.3.3 Rx

A decisive factor in real time audio streaming is the ‘jitter’, or delay variation. To deal with the jitter in the connection, PortaNet provides a tool which allows the user to modify the size of the reception buffer, and so, to compensate the jitter. The maximum value for this buffer is 10 sc.

This value can be changed during the audio connection.

VIII.2.3.4 Test

This tool allows the user to check, in real time the upload/download bandwidth, delay, jitter and packet loss in an IP link between two PortaNets. This information will be used to adjust the streaming parameters in order to achieve the best quality in the audio streaming connection.

PortaNet User Manual 73 of 156

This tool is only available when lines are disconnected.

How to run the tests:

1.- First of all the user must enter the IP address of the remote PortaNet. This dialog stores the last used IP addresses.

2.- Select the test you wish to perform.

3.- To run the test just press the test button:

4.- The values will be shown in a graph, as well as the max, min, last, and mean(avg) values.

4.- Press "STOP" to stop the test or "CLEAR" to reset the readings.

5.- The user can limit the bandwidth used by the test tool:

PortaNet User Manual 74 of 156

By default this test will attempt to send as much IP traffic as possible. If you are using this test on a "live" network then it is desirable to limit the test bandwidth to that which will actually be used. It is also possible to simulate the same packet rate and bandwidth as that configured for the audio connection12.

An accurate figure of total bandwidth used (audio data + overhead) can be obtained from the "Audio Configuaration" screen.

Once the test is finished, it is possible to export the results to an XML file.

VIII.2.3.5 Real Time Monitoring

It is possible to monitor the streaming operation in real time by ticking a checkbox.

Available from version 5.0.0 onwards.

PortaNet User Manual 75 of 156

That indication represents the instant decoder buffer occupation.

When indication is green or even yellow means the streaming is working fine. Depending on the algorithm, the variation will be quicker or slower but always should be going up and down from yellow to the center (green).

If the bar moves towards the red area, it means that it is getting closer to buffer overflow (red right) or buffer underflow (red left). Of course, if you have buffer overflow or underflow you will have a cut in the audio. If the indication goes to red for an instant, usually doesn't affect the streaming, but of course, if you have a constant red indication you are having problems with the streaming.

Buffer underflow might be caused by lost packets or because the clock of the AD converter at the transmitter side which runs slower than the DA converter at the receiver side.

Buffer overflow might be caused by the opposite scheme: The clock at the transmitter side is running quicker than the clock at the receiver side.

Prodys PPL adjustment mechanism is aimed at dealing with this clock jitter and thus to compensate for this variation and guarantee proper audio over IP.

This option also enables the Real Time Analyzer control graph under the streaming bar. By clicking on the graph, the real time analyzer window will appear. For more information about the real time analyzer please read chapter IX.6.7 - Proprietary set of Protocols v2.

VIII.3 Call Log

It is also possible to discover automatically all Prodys IP codecs connected to the IP network: In order to make easy the dialling operation over IP networks, a new facility was included in the Dial window. This new tool allows the discovering of the Prodys IP units connected to the network.

There are two options to discover the units on the network:

1.- The PortaNet sends a broadcast message. This is the default option and it is not necessary to enable anything but the network must support

broadcast traffic.

2.- When the broadcast traffic is not allowed over the IP network still it is possible to discover the units on the network. The “IP range search” checkbox must be enabled and a range of IP addresses must be introduced for a quicker search.

After selecting the address, to make the call just click on “Dial”.

VIII.8 Alarms

The alarm window allows the user to select the alarms that the unit will check. The unit will notify the occurrence of each of the selected alarms. It is possible to configure the unit to send SNMP traps or emails to notify alarms information.

VIII.8.1 Selecting Alarms

The unit supports many different alarms. The selection menu is opened by clicking over the Alarm area.

PortaNet User Manual 94 of 156

 Voltage Out of Range 12 v Main: The voltage from the main power supply

(AC/DC) is out of range.

 Voltage Out of Range 12 v Backup: The voltage from the backup power

supply is out of range.

 Voltage Out of Range 3.3 v System: The voltage from the 3.3 DC/DC

converter is out of range.

 Voltage Out of Range 5 v System: The voltage from the 5 DC/DC

converter is out of range.

 Temperature Out of Range: The temperature is out of range (over 50ºC).  LAN NOT Present: Not physical level detected in the LAN port.  LAN Traffic: The LAN traffic is higher than the 90% of the capacity of the

network.

 No Audio input level detected: No audio is present on the input. A

threshold and a time period can be defined to activate the alarm.

 ISDN NOT Present: Not physical level detected in the ISDN port.  Decoder 1/2 Framed Lost: The Line is connected but the decoder is not

framed, but it was framed before. The alarm will be activated also if the unit is turned off. In this case, the alarm will indicate the date and time when the decoder lost the synchronization, that is, when the unit was turned off. The alarm will be activated until the unit is framed once the line is connected again. If the connection is not possible, the alarm will be marked as finished.

 Decoder 1/2 Not Framed: The Line is connected but the decoder is not

framed. This new alarm doesn’t require that the decoder was framed previously. For this reason, it is necessary to specify a window time to decide when the alarm will be activated once that the NOT FRAMED condition has been detected.

Otherwise, the alarm would come up as soon as the connection is established, given that the Decoder needs some time to detect the incoming compression mode.

 Line Disconnected: Line 1/2 has been disconnected unexpectedly,

manually disconnected or both.

 Backup Active: The ISDN backup line is working.  General: In internal hardware error was detected by the software.

 System Power Down: This new alarm allows to know if the unit was turn

off and the time that remained in that condition.

VIII.8.2 Monitoring Alarms

When one of the selected alarms is detected, the alarms window is highlighted

VIII.8.3 Alarms History

The alarms are saved on the non volatile memory of the PortaNet. It means that it is possible to know what happened on the past even if the unit was disconnected of the network. The alarms history can be showed by clicking over the lamp or over “History” option in the alarm selection dialogue.

An historical report of alarms in html allows the user to preview and print alarm events.

VIII.8.4 Alarms Notification

There are two different ways to notify alarm events: SNMP v1 traps and emails.

VIII.8.4.1 SNMP traps

It is possible to select an IP address where the SNMP traps will be sent. An SNMP manager located at this IP address will receive and process the information according to the SNMP protocol. These SNMP traps will notify alarm information, that is, an SNMP trap will be sent when an alarm is activated or deactivated, with the time and type of alarm. For this to happen, alarms have to be enabled (see chapter VIII.2.2.5 - Alarms. PortaNet can be fully monitored though SNMP protocol.

VIII.8.4.2 Email

From the alarm dialog the user can enter several e-mail addresses where this information will be sent, to inform about the changes in the status of any alarm. It is also possible to define the sender address of the email.

How does the PortaNet work?

Given the different nature of the two communication standards that the PortaNet supports, the unit has to adopt different configurations while adapting to the characteristics of each network. What’s more, in certain situations, PortaNet is capable of dealing with two independent communications at the same time. This can be a cause of confusion for the user, who may be expecting a certain behaviour or action from the unit but observes another. This chapter is therefore a practical guide to help in understanding just how the PortaNet unit works under different configurations, especially the more unusual ones.

IX.1 Selecting the communications interface

Firstly, when we refer to the ‘communications interface’ we are always referring to the communications port that is used for the transmission of ‘audio data’. The NET option in the main menu is for setting this up. There are three settings available with the PortaNet:

a. PortaNet operating as “IP CODEC”: The PortaNet will be configured to

establish communications via the Ethernet port using the IP protocol.

b. PortaNet operating as “ISDN CODEC”: The PortaNet will be configured

to establish communications via a basic access ISDN connection. The PortaNet has a multi-protocol ISDN terminal socket ready for connection to a basic rate 2B+D interface.

The Ethernet interface is always available for remote control of the unit, even if it is configured to operate as an ISDN codec.

You should first select the network type - i.e. the communications interface - to be used for audio data transmission and reception. The menu will only show the configuration options relevant to the network type selected. Of course, there are a number of general parameters that will be the same across all network types and so will not be affected when the network type is changed.

IX.2 Configuration parameters that are dependant on the

network type selected

There are two fundamental reasons for which the user must change the PortaNet configuration parameters when a new communications interface is selected:

PortaNet User Manual 99 of 156

 The available bandwidth over the selected network (IP, ISDN). This places

limitations on the bit-rate that can be selected and the amount of compression. As an example: over ISDN it is not possible to send uncompressed audio and the maximum bit-rate for any algorithm is 128Kbps.

 The number of available channels: Number of bidirectional communications

which can be achieved. Note that over ISDN and IP, up to two independent mono communications can be achieved.

The following table shows what the differences between the various communications networks regarding PortaNet operation:

IX.3 PortaNet 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 PortaNet) 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 with MONO signals on each channel. To avoid incorrect configuration there are therefore certain restrictions while working with the PortaNet as a “DUAL CODEC”:

Over IP, the second MONO communication is fixed to G722.
