WEB BROWSER CONTROL

Prodys IP Family codec can be controlled remotely by using an Internet Explorer
web browser. The computer can be locally connected directly via a crossover
CAT-5 cable, sharing the same Ethernet switch with the codec’s LAN interface or
remotely via the Internet.

To access the Prodys IP Family codec from the Internet Explorer, enter the IP
address of the unit in the address bar. Keep in mind that the Prodys IP Family
codec 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
the first time.

4

Installation Requirements

1.- Pentium 166 or higher.

2.- 64MB RAM minimum.

3.- Operating Systems:

Microsoft Windows XP, Microsoft Windows 2000,

Microsoft Windows NT 4.0 Service Pack 6 or higher,

Microsoft Windows Millennium Edition (ME), Microsoft Windows 98.

Microsoft Windows Vista.

4.- Microsoft Internet Explorer 5.0 or higher.

The screen resolution must be 1024x768 minimum.

4

Some Prodys IP Family codecs are provided with a front panel display and keyboard. For these

devices it is possible to set directly the proper IP configuration before gaining access by means of

the web browser. Please refer to the “HW and Reference Manual” of your codec for details.

Chapter II

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 10

The first time that the computer accesses the Prodys IP Family codec it is

necessary to install the software. The computer will show the following

window:

The unit is supplied with the following IP address: 192.168.100.100

Please refer to the Hardware and Reference Manual if the IP address is unknown.

A procedure to recover the factory default configuration is described.

The first time the user accesses the Prodys IP Family codec 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, the following message
can appear when first accessing the Prodys IP Family codec web page:

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 11

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.

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 12

Windows Vista: Should the user experience a problem when downloading the
OCX file when first accessing the web page of the unit,

please disable UAC (User

Access Control) on Windows Vista.

Once the OCX file has been installed in the

computer, UAC can be enabled again.

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 Prodys 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.

To access the Prodys IP Family codec from the Internet Explorer enter the IP
address of the unit in the address bar as shown here:

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 13

User can choose whether to gain the Web Browser access to the codec with

monitor or control privilege. Bear in mind that only one web browser at a time

can control the unit. However, it is possible to monitor the unit from several web
browsers simultaneously.

If a unit is already being controlled by a web page and we try to get the control
from another web browser, a message will appear. This message will indicate
that the unit is already being controlled from another PC and the IP address of
this computer.

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 14

It is possible to get the control by pressing OK. Then, the connection of the old
owner will be closed and the unit will be blocked for new controller.

This system is fully integrated with the ProdysControl. In that way, the
control from/to ProdysControl can be revoked. It is possible to have a unit
being controlled by ProdysControl and at the same time, web browsers
monitoring the same unit, etc…

When entering the web page, the user can set the time-out period for the
connection between the PC running the web browser and the unit. By default,
this period is set to 5 seconds. To modify this parameter, click on the advance
features button of the login window,

then define the new value from the following window:

The user should take into account that the longer the time-out, the less likely it
is that the connection between the PC and the unit will be lost.

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 15

The user control Timeout definition does not affect the audio streaming protocol
Timeout.
Base Port: When Prodys IP Family codec ports have been modified since the
factory default configuration, it will be necessary to indicate the new port at the
Prodys IP Family codec web browser address line. An example is given at the
end of the green remarked box.

MORE ABOUT THE PRODYS IP FAMILY CODEC PORTS

Changing Prodys IP Family codec Ports: The Prodys IP Family codec
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.

 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 for management and for the audio
communications over IP with Prodys V1 and V2 protocols (Prodys V3 uses
different ports other than these ones). From this base port on, up to 32 ports
should opened/forwarded. That is, if the base port is set to 50011, the range of
ports goes from 50011 to 50041 (plus 51000 and 51001), both for UDP and
TCP. Therefore any modification of the default values should be taken into
account (e.g. opening /forwarding in the corresponding router/firewall if
required).

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 16

IMPORTANT

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

 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>:<Port> Example: 192.168.0.10:8080

Once the page is entered correctly, the web browser will display the “Home
Page”:

The Prodys IP Family codec Web page is arranged in three main areas:

 General Configuration area.

n

 Control area.

o

 Monitor area.

By clicking on any button on the menu bar or any highlighted zone, individual
configuration pages are displayed.

Clicking on the ‘Call Log’ button brings up the Call Log: A history report has
been included to record the input and output calls according to the following
information: telephone/IP, audio modes, date and start/end time, length of each
call, etc…

QUICK START

This chapter guides new user thru the basic steps to start an audio connection
over IP between two Prodys IP Family codecs.

Furthermore this example is also a good starting point for users focused on audio
connections over ISDN or X21. (Please refer to section V.7 and V.8 for a detailed
guide for those networks).

Given is:

 Both codecs are connected on the same Local Area Network.

 The user gains control access to the codec as detailed in chapter II.

 The codecs remains with the factory default settings (but the IP address).

To recover the factory default configuration, please refer to heading of the
configuration chapter (IV).

Page 22

III.4 Dialling the destination codec

The last step is to dial the destination codec according to the figure. Parameters
to match are the IP Address of the remote codec and the codec number

7

(by
default codec 1).
Please refer also to section ¡Error! No se encuentra el origen de la
referencia. for related information.

Immediately the audio streaming over IP takes place between both codecs. The
user gets feedback of the dialling success with a green connection indication.

III.5 Stopping a communication

The user might stop an audio stream in progress by double clicking the upper
green connection indication at any time.

III.6 Encoder and Decoder status indication

Upon the selected network interface and protocol, there are several status
indications available for the encoder and decoder part of the codec:

 <No physical Line>: The communication line is not physically detected. The

user is kindly asked to check the network interface cable.

 <Connected>: The line is connected. An arrow will indicate if it is an

incoming or outgoing call.

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 24

The duration of the call also is indicated.

 <Disconnected>: The line is detected physically but no audio streaming is in

progress. Beside the text appear the disconnection codes.

 <Disconnected (Connection Rejected)>: The far-end codec is addressed, but

this codec can not take the call because the codec is busy or the Target

codec is not available

8

.

 <Calling>: A dialling is in progress or the codec is waiting for the far-end to

complete the invitation (eg. manually answer at the far-end)

 <Ring>: Receiving an in-dialling call on the line.

III.7 Decoder Status

Further information is applicable only to the Decoder status:

 <Searching>: The decoder is not synchronized yet with the incoming audio

stream at the receiver. The decoder engine is searching to get in sync with
the proper compression algorithm.

 <Framed>: The decoder is synchronized.

 <Stopped>: Some restriction applies for the Decoder and therefore signal

will not be available at the audio outputs. (eg. the codec has not got a valid
Prodys’ license for the incoming compression algorithm, or the Decoder and
Encoder compression algorithms are incompatible on the same codec.)

CONFIGURATION

Clicking on the <Config> button from the top web browser control page brings
up the configuration page:

The factory default configuration can be restored by pressing <Restore Default>
& <OK>. This option allows the user to restore the factory default configuration,
except those parameters related to the LAN configuration: IP address, netmask
and gateway.

Chapter IV

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 26

To apply the changes, the user can press either the <OK> button or the

<Apply> button. By pressing the Apply button the changes will be applied but

the configuration window will remain.

<Export>: This option copies the complete codec configuration to the computer

disk. The user is requested to indicate the computer directory.

<Import>: It copies the complete codec configuration from the computer

directory. This imported configuration is placed in force as soon the <OK> or
<Apply> button are pressed.

IV.1 Interfaces

By clicking on the <Interfaces> menu, the port configuration dialog appears. The
ports can be selected on the left side (LAN, ISDN, X21, PSTN, RS232 or GPIO).
The right window shows the window dialog to configure the selected port. For
example, if we select the LAN interface:

IV.1.1 LAN port

The first definition on this menu is the <Device Name>, which sets the IExplorer
tab label with a meaningful indication. This name will be also available on the
front panel display, and it will be used to send alarm email alerts when enabled.

Prodys IP Family codec allows the assigning of the IP parameters either manually
or automatically (by DHCP).

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 27

Manually Æ User must enter the following IP parameters manually:

 <IP address>
 <Mask>
 <Gateway IP address>

Automatically Æ Check “Obtain an IP address automatically” option to get the

configuration automatically from a DHCP Server.

By setting DHCP, the codec will get its IP parameters when starting up. This IP
setting might be different from time to time, that is why Prodys IP Family codec
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.

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [e-mail] Θ Web: www.prodys.com

Page 28

• 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:

As can be seen from the picture, the DNS information can be obtained
from a DHCP Server.

IV.1.2 Ports

It is possible to configure which ports the unit will use when selecting Prodys
proprietary protocols for IP communications.

There are two different groups:

 <Web Server Port>: By default, it is TCP port 80. This is the internal web

server port.

 <Base Port>: By default, it is 50011 for TCP and UDP ports. This is the

first port of the range of ports used by Prodys Proprietary Protocols V1 &
V2, along with the management ports. From this base port, up to 30 ports
should be 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), in order for the audio and management traffic is routed
appropriately to the ProntoNet. This is the simplest way to deal with the
port configuration of routers/firewalls. In case only the management ports
have to be opened a more detailed list of ports and different configuration
examples are provided in chapter V.6.4 More about Prodys Proprietary
Protocols.

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>:<Port

> Example: 192.168.0.10:8080

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:

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.

When establishing a bidirectional call with Prodys IP codecs using Prodys
Proprietary Protocols V1 or V2, two connections are made automatically, one for
each direction. For the receiver to call properly to the caller (

only in case the

base port in the caller is not the default one

), it should have an entry on its
phone book with the IP address of the caller and the base port of the caller.
Example: if the caller has the IP address 10.1.5.0 and its base port is 40011, in
the receiver, the following entry should be configured in its phone book:
