INTRODUCTION
Prodys IP Family codec stands for a large range of compatible audio codecs from
Prodys. Those codecs allow applications as dual and multi audio codec by
supporting MPEG 2/4 AAC LC, MPEG 4 LD & HE and apt-XTM amongst other
standard algorithms, as well as bidirectional uncompressed audio transmission
over IP.
A Prodys IP Family codec is also a Multi-network audio codec that can be used
for audio streaming over a suite of communication networks:
ISDN 1-BRI (U or S/T interfaces)1.
X21 synchronous data transmission links (Digital Leased Line: DLL)2.
LAN connector, 10/100Base-T Ethernet interface for audio transmission and
control (audio streaming over private IP networks or Internet).
PSTN connector, to connect to Public Switched Telephone Networks3.

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.
4Some 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] ΘFax: [phone] ΘEmail: [e-mail] ΘWeb: www.prodys.com

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] ΘFax: [phone] ΘEmail: [e-mail] ΘWeb: 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] ΘFax: [phone] ΘEmail: [e-mail] ΘWeb: 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] ΘFax: [phone] ΘEmail: [e-mail] ΘWeb: 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] ΘFax: [phone] ΘEmail: [e-mail] ΘWeb: 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.

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).

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. p

Prodys S.L. Tel: [phone] ΘFax: [phone] ΘEmail: [e-mail] ΘWeb: www.prodys.com

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…
