Chapter 1 : Introduction

The EQUITEL audio over IP devices family allows the transmission and reception of music channels and audio
messages over IP, using standard IP network hardware.

These devices provide a unified solution for transmitting audio signals such as background music, advertising and
informational messages, to one or more destinations.

By supporting multiple protocols and encoders, these devices are indicated in broadcasting application s, VoIP
and Internet radio. In addition to leveraging existing infrastructure and devices such as SIP phones.

Music server (E430), Encoder (E421) and console (E495 / E497) send audio input through the network. This
process is known as "streaming". Streams can also be generated by other devices, like a PC running an
application or a SIP phone.

Decoders (E411, E413 or E415) can receive selected channels (i.e. "streams") from the network and convert it
back to an analog audio signal.

Mixer (E417), besides the same features than the decoders, includes the option to use audio coming from files
stored in a USB memory or analog signals in its MIC or LINE inputs.

The selection of the actual stream, local file or analog signal to be sent to the output is made based on a
powerful but very easy to configure priority schema.

The figure shows a schematic of this family of devices usage:

Figure 1 - EQUITEL Audio over IP devices usage schema

E430 IP music and announcements server. User’s manual Page 2

This document is the user's manual for the encoding members of the family:

E430 - Server

 Generates Icecast

1

and RTP2 streams for background music.

 Provides announcements from digital audio files, periodical

or scheduled.

1

Icecast is a streaming media server software distributed under the GNU GPL, version 2

2

RTP is a transport protocol, the audio is sent in RAW format or following the RFC2250 protocol, according to configuration

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 3

Chapter 2 : Functionality

2.1 Audio source types

The E430 server can transmit sound from mp3, ogg, wma and wav audio files. Some of them may require a
conversion, which is automatically made when transferring them from a PC.

2.2 Announcements, scheduled and BGM – RTP generators

The E430 server can send audio files over a RTP network to up to 100 different destinations in three different
qualities:

 G711/A:

This is the recommended quality for voice transmission, it sends audio with a bitrate of 64 kb/s (8 bits
per sample, 8000Hz sample frequency). It is one of the most commonly used standards in VoIP
technology.

 PCM 11025 Mono:

This is the recommended quality for music transmission and data bandwidth saving, it sends audio with
a bitrate of 176,4 kb/s for each destination (16 bits per sample, 11025Hz sample frequency).

 PCM 32000 Mono:

This is the recommended quality for music transmission, it sends audio with a bitrate of 512 kb/s (16
bits per sample, 32000Hz sample frequency).

 MP3:

This is the higher quality available, it sends mp3 audio with a bitrate up to 192 kbps (16 bits per
sample, 44100Hz sample frequency).

2.3 BGM - Icecast generators

Up to 6 different radio stations with mp3 quality can be generated, each one of them supports up to 100
clients, but network bandwidth has to be considered, depending on the qualities:

 64 kbps stereo (per client)
 96 kbps stereo (per client)
 128 kbps stereo (per client)
 192 kbps stereo (per client)
 Source quality. It sends the mp3 files without converting them, provided they have constant bitrate

with a bitrate up to 192 kbps

4.1 Accessing the device

Connect the device to the Ethernet network and the power supply.

Press the power button if necessary (A blue light comes from it when it is turned on).

The devices are configured in factory to acquire its IP address by DHCP. If your network has a DCHP server, it
will assign a valid IP to the device about 40 seconds after turning the device on.

If there is no DHCP server or is not accessible for any reason, after approximately 1 minute of not being able
to connect, the device will configure itself with the following access parameters:

IP:

192.168.1.1

Subnet Mask:

255.255.255.0

Gateway:

192.168.1.254

To know the IP address of the device in order to gain access to it:

 Use the free "EQUITEL Devices Searcher" application, for locating Equitel devices in an Ethernet

network. This app is available at ENA main website

In this example the E430 IP address is ‘192.168.1.161’.

Once the IP is known, you can access the web server as detailed in the following section. For further details
about discovering a device, please see section 5.3

NOTE: When accessing the web page, a Javascript enabled browser is needed. The following were tested:

4.2.2. Generators

This page contains the ‘Destinations, ‘Announcements’, ‘Scheduled’ and ‘Icecast’ subsections.

4.2.2.1. Destinations

Prior to configuring an announcements or scheduled generator, you should set the possible
destinations of the audio. Each destination is the combination of an IP address and a RTP port.
Additionally, an ID may be specified to ease the configuration (ENA decoders may have different
qualities in different ports, so it is a good idea to set an ID according to the quality). A more detailed
configuration is available at section 5.4

VERY IMPORTANT. Once you’ve finished the destinations configuration, press Apply so as to make
them available for the generators.

E430 IP music and announcements server. User’s manual Page 13

o Normal, to sequence files in alphabetical order.
o Random, to send files in random order.

 Destinations: A list of all the destinations available. As stated before, be cautious about the

qualities, to avoid sending audio in a format the destinations don’t have configured.

 Announcement files: Each generator have a fixed folder which contains the .wav audio files

available for broadcast. You can change it only when the generator is first added. The default
folder ‘\’ may be used.

 Audio file selection: A list of files matching the selected quality in the music folder is shown when

pressing View files . Then you may check the files you want this generator to send. Files will be
sent in alphabetical order.

To add new files from the PC, press Add files and select files from the PC, once converted the
new files will be listed after pressing View files .

Press Apply to commit all changes made in the generator (if the configuration is invalid then an error
message will be shown next to these buttons). Press Close to discard changes made in the generator.

NOTE: Added files won’t be lost. To ease the uploading process, files are converted to all available wav
qualities, in such a way that the action of changing quality does not affect which files are choosable to
be sent.

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 14

4.2.2.3. Scheduled

This generator sends an announcement with a fixed schedule.

Similarly to the announcements generator, a short briefing is shown, to know more about the
configuration process, view section 5.6

 Id: Field to distinguish this generator from others.
 Quality

4

: Quality of the audio sent. It must match the destinations one.

 Start automatically: If checked, the generator will start to check the conditions for sending

files right after saving the configuration, and when the device boots up. If unchecked, the
generator has to be enabled manually at the ‘Status’ section.

 File: File to send. The folder for this generator is always ‘\Scheduled’ (as each generator only

sends one message), and the add files option is added, which works just the same as the
section in the announcements generator.

 Destinations: A list of all the destinations available. As stated before, be cautious about the

qualities, to avoid sending audio in a format the destinations do not have configured.

 Schedule: List of individual conditions that must meet the system time in order to send the

announcement:

o If it is set to don’t care (*), the condition won’t be checked.
o In this example, the minute is the first condition specified, which means that the

announcement will be sent on the hour. This allows for an advanced schedule, if
several conditions are set.

Press Apply to commit changes made in the generator (if the configuration is invalid then an error
message will be shown next to this buttons). Press Close to discard changes made in the generator.

4

When quality is MP3, you should check which firmware version the ENA decoders have, as it may be necessary to activate the

‘Legacy RTP mp3’ checkbox in the Network configuration.

Figure 10 - Scheduled generator configuration

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 15

4.2.2.4. BGM - Icecast

This generator allows you to create an mp3 stream in the Icecast format.

Here is an outline, for additional information, go to section 5.7

 Id: Field to distinguish this generator from others.
 Bitrate: Quality of the mp3 stream. Mp3 files are converted on-the-fly

5

unless the ‘source files’

option is selected. In that case, only mp3 files with a CBR6 up to 192kbps will be streamed.

 Stream URL: This is the complete address to set in any receiver. Different generators do require

different stream URLs. It is advisable to end the URL in .mp3, although it is not compulsory.
In this example, the Icecast URL to set in a decoder would be:

‘http://192.168.1.185:8000/streamE430.mp3’

 Start automatically: If checked, the generator will start the stream right after saving the

configuration, and when the device boots up. If unchecked, the generator has to be started
manually at the ‘Status’ section.

 Emission mode:

o Normal, to sequence files in alphabetical order.
o Random, to send files in random order.

 Music folder: Each generator have a fixed folder which contains the .mp3 audio files available for

broadcast. You can change it only when the generator is first added. If you want to share the
files among generators, default folder ‘\’ may be used.

5

This means the files are converted right before they are used. This conversion adds some CPU work overhead.

6

CBR stands for Constant Bitrate. Mp3 files can also be variable bitrate (VBR) or average bitrate (ABR) ones.

Figure 11 - Icecast generator configuration

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 16

 Audio file selection: A list of mp3 files in the music folder is shown when pressing View files . To

add files from the PC, press Add files and select files from the PC, once they are converted (if
they are not .mp3 files compliant with the ‘source files’ option) the new files will be listed after
pressing View files . Files checked will be sent in alphabetical order.

Press Apply to commit changes made in the generator (if the configuration is invalid then an error
message will be shown next to this buttons). Press Close to discard changes made in the generator.

4.2.2.5. BGM – RTP

This generator allows you to create an RTP stream in mp3 or pcm formats. Files are sent continuously.
For a detailed example of configuration, go to section ***

 Id: Field to distinguish this generator from others.
 Quality

4.3 FTP server

The device provides access to the music folders via the FTP protocol. This may be useful to mass deletion of
audio files and folders. However, only advanced users should take advantage of this possibility, as a
configuration reset may be needed if files are being used in the device configuration.

You should NOT add new files from your computer via FTP, unless you’re sure the audio formats match the

formats of the generators, and this is ensured by the upload & conversion process available at the web
generators configuration.

IMPORTANT. The right way to work with the audio files via FTP is:

 Reset current configuration via the web server (view section 4.2.3.4)
 Connect to the ftp server and modify the files you want.

The credentials for accessing the ftp server are:

User:

Chapter 5 : Step-by-step configuration example

5.1 Device arrangement

The E430 is easy to setup, let’s suppose we have these devices:

Devices IP adresses:

 E430: ‘192.168.1.120’
 E413: ‘192.168.1.130’
 E415: ‘192.168.1.131’
 E417: ‘192.168.1.132’

5.2 Devices requirements

The E430 emitter should have at least this configuration:

 An announcements generator for E413, E415 and E417.
 A scheduled generator for E417.
 BGM music via an Icecast stream for any device connected to the network.
 BGM – RTP stream for E413 and E415.

There are three receivers:

 An E413 decoder, which will play periodical announcements from the E430 device, and BGM music from

the RTP stream.

 An E415 decoder, which will also play the announcements, and BGM music from the Icecast stream or

the RTP stream in the meanwhile.

Figure 19 - Device arrangement example

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 23

 An E417 decoder, which will be playing background music from an USB pendrive or the Icecast stream

and both periodical and scheduled announcements. We consider scheduled announcements as higher
priority ones. We want the higher quality available.

This is a summary of the decoders configuration, translating the previous information into their priority
model, and assigning a valid RTP port or a valid URL for the Icecast stream (to further information on how to
configure them, please have a look at the ENA decoders manual):

5.3 Generic settings

First of all, we should check the network settings. To do that, we start the “Discover” App, which
allows us to find the E430 device in the network, know its ip and change its network settings. And then, we
press Find devices . The E430 device must be switched on.

Figure 20 - Discover of the E430 device

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 24

Once it is discovered, we can change the settings to match that of our scenario. That is, assigning it
an static IP, 192.168.1.120. We select it so its configuration is available at the right side of the app and
introduce the new settings.

After pressing Accept , a confirmation dialog shows, after confirming it we press Find devices again.
As a result of our actions we can see the device changes its IP, which makes it possible to continue with the
rest of the configuration.

5.4 Destinations configuration

We enter the E430 webpage by entering the recently set IP 192.168.1.120 in our browser.
Afterwards, we enter the ‘Generators’ tab. There the first subpage is ‘Destinations’. Before starting to
configure this section, we have to wonder: ‘how many destinations do we need?’

The destinations apply to announcements, scheduled and BGM-RTP generators, and we need one for each
device channel (a destination is an IP/port combination). Recalling from the introductory example, these are
the advertisement channels for each device:

E413 (IP address 192.168.1.130)

 AD2 channel: PCM 32000 Mono, RTP port 6002. (Announcements, normal priority)
 BGM2 channel: RTP, MP3, Port 6004 (BGM – RTP)

E415 (IP address 192.168.1.131)

 AD2 channel: PCM 32000 Mono, RTP port 6002. (Announcements, normal priority)
 BGM2 channel: RTP, MP3, Port 6004 (BGM – RTP)

E417 (IP address 192.168.1.132)

 AD1 channel: PCM 32000 Mono, RTP port 6000. (Scheduled, high priority)
 AD2 channel: PCM 32000 Mono, RTP port 6002. (Announcements, normal priority)

Consequently, four destinations will be added, we label them with a meaningful id:

 Destination 1-> Id: ‘E413 Ad2 announcements’, IP: ‘192.168.1.130’, Port: ‘6002’
 Destination 2-> Id: ‘E415 Ad2 announcements’, IP: ‘192.168.1.131’, Port: ‘6002’
 Destination 3-> Id: ‘E417 Ad1 scheduled’, IP: ‘192.168.1.132’, Port: ‘6000’
 Destination 4-> Id: ‘E417 Ad2 announcements’, IP: ‘192.168.1.132’, Port: ‘6002’

After entering the information in the web (by pressing Add and Edit when necessary) , this is the result.

5.5 Announcements generators configuration

We wanted periodical announcements for both decoders. Assuming the announcements files must
be the same for them, there is only one generator to setup. Let’s enter the ‘Announcements’ tab inside
‘Generators’, and press Add .

We enter the first settings:

 Id: ‘Announcements 1’, a simple one.
 Interval (the silence between announcements): ‘300’ seconds
 Quality: ‘PCM 32000’ as it is the higher available.
 Start automatically: ‘true’
 Emission mode: ‘random’. If you want a fixed order for the files, select ‘normal’.

Selecting the appropiate destinations is easy thanks to our labeling of the destinations ids, we mark

‘E415 Ad2 announcements’ and ‘E417 Ad2 announcements’.

What is left is the announcements folder and the files to play. To do that, we create a folder by

pressing Create and we enter a name for the folder, for instance ‘Announcements’ , which we

should Confirm . By now this should be the aspect of the configuration:

The uploading of the files is probably one of the most important things to understand. Let’s suppose
we have a folder in our PC with the announcements we want in ogg format: add1.ogg, add2.ogg… up to 15
different announcements. After a click on Add files and the Browse files button which will appear below it,
we go to the folder containing the announcements and we select all 15 files. If the size of all the files were
greater than 100 MB (which is the maximum size per upload), we should have selected less files, and do the
uploading in two steps.

Figure 24 - Announcements generator configuration

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 27

Once the files are selected, we press Upload & Convert , the message ‘Starting conversion, please
wait’ appears, and then we wait until the ‘Task completed’ message appears. It should take less than a

minute.

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 28

After pressing View files , all the files converted should be visible.

We press Apply , as we want all the files to be played, and that finishes our announcements
generator configuration.

5.6 Scheduled generators configuration

Scheduled announcements were needed for the E417 device. What is most important for these
generators is to know clearly how many messages we want to send and when. Each generator sends a
message. Let’s suppose this is the schedule:

 ‘scheduledMessage.mp3’ on Monday to Friday, is sent every 30 minutes. For instance it could be a

message in an airport sent in order to remember passengers to look out their belongings.

 ‘scheduledMessage2.mp3’ is sent everyday at 11.30 am, 12.30 am and 1.30 pm. It could be a paid

advertisement, which has to be played three times a day.

Having two messages, we need two scheduled generators. We need to go to the ‘Scheduled’ subpage

and we start to configure the first one. To do that, Add is pressed and we enter these settings:

 Id: ‘From Monday to Friday’
 Quality: ‘PCM 32000’ (It may be a different one, but this ensures high quality)
 Start automatically: ‘true’
 Destinations: ‘E417 Ad1 scheduled’

We add the files, not only for this generator, but also for the second (scheduled generators share the
same music folder). To achieve this, we proceed exactly as we did with the announcements generator,
selecting the files in our PC after pressing Add files and then pressing Upload & Convert . There is one
difference: when the conversion is complete, the button Update file list should be pressed. After that, we
proceed to select the proper file for this generator in the combo.

Figure 29 - First scheduled generator configuration

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 30

And last but not least, the schedule. It is crucial to comprehend how this works. If we press

Add under ‘Schedule’ at the bottom of the page, this is the default schedule we would get:

When pressing Edit after adding a schedule there are several fields to configure. Whenever a field is
set with the value ‘*’, the field does not restrict the schedule. For instance, the default value is ‘*’ for all
fields. That means the message will be played when the condition ‘minutes equals anything’ occurs, therefore
every minute.

Another example: if we wanted a song to be played every day, on the hour, the setup would be the
same,but with the minutes field set to 0.

Figure 30 - Scheduled audio file selection

Figure 31 - Default schedule configuration

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 31

To achieve the schedule of the first generator, the conditions which the time needs to match are the
minutes being 0 or 30, and, in addition to that, the days of week being from Monday to Friday. Each row is
generated by pressing Add below ‘Schedule’ and then pressing Edit to enter the final values. This is the final
schedule for the first generator:

With this, and after selecting ‘scheduledMessage__32k.wav’ (which is the message we wanted to send in

the first place), the configuration is finished, we press Apply on the page bottom to commit the changes.

Figure 32 - First generator final schedule

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 32

The start of the configuration of the second generator is similar, after pressing Add below ‘Scheduled

generators list’ the first settings to be introduced are:

 Id: ‘Everyday’
 Quality: ‘PCM 32000’ (highest)
 Start automatically: ‘true’
 File: ‘scheduledMessage2__32k.wav’
 Destinations: ‘E417 Ad1 scheduled’

Then we add a schedule. Now the conditions to meet are the time being 11.30 am or being 12.30
am or being 1.30 pm. After adding these three requirements this is the result:

We Apply the settings and with that the scheduled generators configuration is finished 8.

8

We have set a configuration with a potential conflict, because the first generator is also active when the time is 11.30, 12.30 and

13.30. In section 5.9 this conflict will be explained.

5.7 BGM - Icecast generators configuration

We go to the ‘BGM - Icecast’ subpage and press Add .

The first settings to enter are:

 Id: ‘Icecast 1’, to maintain it simple.
 Bitrate: ‘192 kbps’ (the highest quality).
 Stream URL: ‘stream1.mp3’ as specified. (The complete url is to be typed at the decoders)
 Start automatically: ‘true’
 Emission mode: ‘Random’, so that the background music is not always in the same order.

As in the announcement generators, a folder needs to be defined. We create a folder named
‘Icecast1’ after pressing on Create .

And after pressing Confirm :

Figure 36 - Folder creation

Figure 37 - Folder confirmation

July 2015 - Ed.1.2

E430 IP music and announcements server. User’s manual Page 34

All that is left is the audio files to be played. For this purpose, we have in our PC a folder with 15 mp3
files named ‘file01.mp3’, ‘file02.mp3’… ‘file15.mp3’. We press Add files , then Browse to select them in our
PC, and after that Upload & Convert to send them to the E430. After a while, this will be the Conversion
progress result:

When that happens, pressing View files will make a list with all the files checked appear.

We do not want to change which items are played, so we press Apply and we save the configuration
of all generators by pressing the top button Save & Apply

5.8 BGM – RTP generators configuration

We go to the ‘BGM - RTP’ subpage and press Add .

We enter the first settings:

 Id: ‘Rtp 1’, a simple one.
 Quality: ‘MP3’ as it is the higher available (For ENA decoders v3.06 and above)
 Start automatically: ‘true’
 Emission mode: ‘random’. If you want a fixed order for the files, select ‘normal’.

This time the destinations checked should be ‘E413 BGM2 RTP’ and ‘E415 BGM2 RTP’.
The folder is created with the name ‘bgmRtp1’ following the same steps as in the other generators. This

should be the aspect of the configuration:

You may add the files as it was done in the other generators. After that, press View files , the mp3 files should
be listed and checked. Apply the configuration.

NOTE: You should check which firmware version the E413 and E415 device have, as it may be necessary to
activate the ‘Legacy RTP mp3’ checkbox in the Network configuration.

5.9 Control of the generators

Once the configuration is saved, you may access the ‘Status’ tab to view the status of the sources
and control them.

Here is a brief examination of the status page content:

 The announcements generator ‘Announcements 1’ is currently waiting to send the second

announcement, and the date is when this announcement will be played. We could force the
emission by pressing Send now , or Stop the generator if we desire so. In addition to that, it is
possible to advance to the Next announcement or move back to the Previous one.

 The scheduled generators ‘From Monday to Friday’ and ‘Everyday’ are waiting for the next condition

to become active, and the moment is June 10th,2015 at 12.30. This illustrates what happens if we set
the same conditions for generators sharing a destination, the audio would be sent at the same time
and, as a result, the audio received at the decoders would not be correct. This problem can be fixed
setting different conditions for the second generators, for instance being active at 11.15 pm, 12.15
pm and 1.15 am.

 The BGM - Icecast generator is sending the fourth file, but has no clients. Once a decoder is turned

on and playing this generator, the clients number number would increase.

 The BGM – RTP generator is sending a file, we can advance to the Next announcement or move

back to the Previous one if we desire so.
