1. DESCRIPTION
1.1. The IPA3000C01
The IPA3000C01 module is an automatic DVB-ASI and DVB over IP switch that performs
switching based upon presence of signal at the inputs, reception of frame
synchronization and information received via the GPI connector as per the priorities
assigned by the user to each input.
The module includes two inputs, MAIN IN and RES IN through which it receives two
DVB-ASI frames labeled "ASI MAIN" (the main DVB-ASI input) and "ASI RES" (the reserve
DVB-ASI input). The unit also includes a 1Gbit/s Ethernet port through which it can
receive two DVB over IP frames (UDP and RTP, with or without FEC) labeled "IP MAIN"
(the main DVB over IP input) and "IP RES" (the reserve DVB over IP input). Any of the four
frames can be activated or deactivated. Whichever input is currently selected will be
distributed to the four DVB-ASI outputs and can also be transmitted over IP using the
Ethernet port. In case of power supply failure or extraction of the module from the
mounting frame a bypass relay on the rear board connects the ASI MAIN input (MAIN IN)
to the protected output (OUTp).
The IPA3000C01 module can operate in two different modes depending upon the type of
signal received. One mode is valid for any DVB transport stream (TS) whereas the other
can only be used with DVB-T transport streams. The characteristics of each mode are as
follows:
• Generic DVB mode:
-Capable of seamless or non-seamless operation (Seamless operation only with model
versions 1.3 and higher).
-Error detection for the inputs is based upon signal level and the presence of DVB
frame synchronization.
-The 1 pulse-per-second (1 PPS) and 10MHz reference inputs are not used in this
mode.
• Dedicated DVB-T mode:
- Seamless-only operation.
-Error detection for the inputs is based upon signal level, the presence of DVB frame
synchronization and the presence of megaframe synchronization (MIP packets).
-The 1 PPS reference input is used to measure the delay between the input signals and
to provide a reference delay for the output signal.
5

Albalá Ingenieros | Manual IPA3000C01
-The output delay is set by the user and is independent of the delay from the input
signals. The output delay must be greater than the input delay in order for the
module to operate properly.
-Each input includes a 29696 packet buffer, allowing a delay of up to one second for
any TS up to 40Mbit/s.
In order to perform seamless switching for DVB-T frames the IPA3000C01 includes a 1
PPS reference input and a 10MHz reference input for synchronization of different
transport streams. The module also includes GPI inputs to flag external errors within the
transport streams received and a GPO output to signal that the unit cannot deliver a
valid TS at the outputs.
In addition to functioning as an automatic switch, the IPA3000C01 can be used for other
functions such as conversion of DVB-ASI transport streams to DVB over IP and vice versa,
elimination of jitter in the transport streams being transmitted over IP and the
conversion of IP protocols such as elimination or insertion of forward error correction
(FEC), conversion from UTP to RTP, etc.
The module provides three switching modes: automatic, semi-automatic or manual. All
changes to the input selected or in the status of the inputs are indicated via the front
panel LEDs and a beep.
It is possible to monitor the IPA3000C01 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The IPA3000C01 is a TL3000 terminal line module and can be housed in a three rack unit
(3 RU) UR3000 mounting frame or a 1 RU UR3100 mounting frame.

3. INSTALLATION
THE IPA3000C01 MODULE CONTAINS ELECTRONIC DEVICES SENSITIVE TO
ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified
with a high degree of shielding for storage and transportation.
The IPA3000C01 module is composed of two parts: one IPA3000P01 main board and one
IPA3000P02 rear board. Both parts must be installed in a UR3000 or UR3100 mounting
frame following the instructions in the corresponding section of this chapter.
3.1. Initial inspection
Verify that the package has been properly handled during transport. After opening the
packaging, check that one IPA3000P01 main board and one IPA3000P02 rear board are
inside.
You must notify your Albalá Ingenieros distributor or dealer of any damage or defects
observed.
Follow the instructions in this manual to install this module in the mounting frame.
3.2. Safety instructions
•This equipment must be connected to a mains outlet with a protective
earth connection. Never use extension cords that do not have protective
earthing connection. The lack of an effective electrical connection between
the ground pin in the mains input connector of the equipment and the
protective earth of the electrical power distribution can cause serious harm.
•All modules of the Albalá Ingenieros TL3000 terminal line can be
hot-plugged or unplugged without suffering any damage or affecting the
processes that are currently taking place in other modules in the same
mounting frame. When a module is installed in an empty bay of a mounting
frame, it is necessary to mount the rear board that is part of that module.
Prior to installing this board, the mounting frame must be disconnected
from the power supply network. This is required because in addition to the
risk of electrocution for the person handling the device it is possible that a
high instantaneous current coming from the power supply could damage
the connectors and components of the mounting frame and/or the rear
board.
13

Albalá Ingenieros | Manual IPA3000C01
•The IPA3000C01 module and the mounting frame should always be
installed, maintained, operated and removed by personnel with sufficient
technical qualifications. The equipment should never be placed in damp
areas, near splashing liquid, or in explosive or corrosive atmospheres.
Neither modules nor mounting frames can be used in applications that
could endanger human life.
3.3. Environmental considerations
This symbol indicates that this equipment must be deposited at a collection
point for proper waste treatment once it has reached the end of its useful
life.
3.4. Power considerations
The UR3000 and UR3100 mounting frames can house as many IPA3000C01 modules as
will fit in them.
3.5. Installing the module in the mounting frame
The steps needed to install the IPA3000C01 module with the rear board in the mounting
frame are:
1 - Disconnect all power cords from the power supplies of the mounting frame.
2 - Remove the blank panels covering the front and rear of the empty bays chosen for
installing the IPA3000C01 in the mounting frame.
3 - Install the IPA3000P02 rear board ensuring that its 12-pin connectors are properly
aligned with the mounting frame´s mating connectors. Check that the orientation of
the board is correct by looking at the placement of the text printed on it according to
the illustration below.
4 - Attach the rear board to the mounting frame with two M3 metric screws and tighten.
5 - Insert the IPA3000P01 board (main board of the IPA3000C01 module) into the front of
the mounting frame. The edges of the card slide into two plastic guides inside the
mounting frame.
6 - Affix the main board to the mounting frame using the two screws included on the
front panel.
After these steps, the module is ready to be connected to other equipment.

3.6. Interconnection
The following figure shows the IPA3000C01 module rear board connector layout.
Rear view of the IPA3000C01
The IPA3000C01 module includes two inputs (MAIN IN and RES IN) and four DVB-ASI
signal outputs (OUT AUX,OUT AUX,OUT and OUTp). The OUTp connector corresponds to
the output that is protected with a bypass relay such that signal integrity is maintained
in case of a power supply failure or extraction of the module from the mounting frame.
The unit also includes two reference inputs (1PPS and 10MHz) and an RJ-45 Ethernet
port (ETHERNET). Finally, the module has four GPI inputs (F_IP_R,F_IP_M,F_ASI_R and
F_ASI_M) and one GPO output (F_OUT).
The Ethernet port uses an RJ-45 connector. The cable used should be UTP Cat 5 or better
(Cat 5e or Cat 6) in order to guarantee proper 1Gbit/s operation.
16

Albalá Ingenieros | Manual IPA3000C01
The GPIO interface includes the following signals:
TERMINAL NAME FUNCTION
6 F_ASI_M This input indicates that that an error has occurred in the signal received at the
main DVB-ASI input (ASI Main) somewhere before entering the Module.
5 F_ASI_R This input is identical to the previous one except that is refers to the reserve
DVB-ASI input (ASI Res.).
4 F_IP_M This input is identical to the previous one except that is refers to the main DVB
over IP (IP Main) input.
3 F_IP_R This input is identical to the previous one except that is refers to the reserve
DVB over IP (IP Res.) input.
2 F_OUT This output indicates that no signal is present at the output of the Module.
1 GND Ground connection.
The rear interconnection board is not designed to withstand mechanical stress. The
wiring must be fastened properly to the frame where the mounting frame is housed to
prevent the rear board from supporting the weight of the cables.
3.6.1. Electrical DVB-ASI video connections
All DVB-ASI digital video electrical connections are BNC type. Below are several
recommendations to consider when wiring electrical signals.
BNC connectors used on cables must be suitable for the high frequencies of DVB-ASI
digital video signals: it is strongly recommended to use high quality connectors from
well known manufacturers.
All coaxial cable used must be Belden 8281 or similar. This type provides the greatest
lengths because it is used to calculate the equalizers in the IPA3000C01. Cables
carrying signal between the module and the devices should use single piece
construction, avoiding spliced sections with double BNC female or barrel connectors.
If it is necessary to split the cable into two sections the same type of wire should be
used in both sections.
The use of analog video coaxial cables (RG-59 type or similar) is not recommended for
digital video except for very short distances.

circuit is as follows:
Before connecting these signals please consult the maximum values shown in the
specifications section. Never connect dangerous potentials to GPI inputs.
3.6.3. GPO connections
GPO outputs use 3.81mm pitch terminal block connectors and their equivalent circuit
is as follows:

4. OPERATION
This section describes the significance of the front panel indicators of the IPA3000C01
module and their remote control and monitoring ability.
4.1. Front panel description
The appearance of the front panel and the elements it contains are shown in the
following illustration.
Front panel of the IPA3000C01
The meaning of each LED is explained as follows:
19

Albalá Ingenieros | Manual IPA3000C01
In the INPUT FAIL box:
ASI MAIN,
ASI RES,
IP MAIN,
IP RES: Red. These LEDs light up to indicate errors for the corresponding input.
They light up continuously when no signal is present, when the frame
synchronization fails or when the megaframe synchronization fails (this
last error is only in DVB-T mode) or when an external error has been
signaled via GPI.
In DVB-T mode these LEDs will blink when the TS delay is greater than the
value established for the output.
These LEDs remain off if no errors are present or if the corresponding
input is disabled.
1PPS / 10MHz: Red. These LEDs light up to indicate errors in the 1 PPS or the 10MHz
reference inputs. They light up continuously whenever the signal at the
corresponding input is invalid.
In the ETHERNET box:
LINK: Green. This LED lights up continuously when a link has been established
via the Ethernet port.
ACT: Green. This LED blinks when there is activity on the Ethernet port.
1G / 100M: Green. These LEDs light up to indicate the speed of the Ethernet interface.
1G indicates a speed of 1Gbit/s. 100M indicates a speed of 100Mbit/s. If
both of these LEDs are off and the LINK is lit the speed is 10Mbit/s.
In the INPUT SELECTION box:
ASI MAIN,
ASI RES,
IP MAIN,
IP RES: Green. These LEDs indicate which input TS is being delivered to the
output.
In the MODE box:
AUTO,
HALF AUTO,
MANUAL: Green. These LEDs indicate which operating mode is selected.
SEAMLESS: Blue. This LED lights up when seamless switching is possible. During
Automatic and Semiautomatic modes this LED lights up when seamless
switching is possible between the active input and the highest priority
input of the remaining three inputs. In manual mode this LED lights up if
a seamless switching is possible when the SELECT is pressed.
