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 1Gbit/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 10MHz 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 40Mbit/s.
In order to perform seamless switching for DVB-T frames the IPA3000C01 includes a 1
PPS reference input and a 10MHz 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.

1.2. Features
•Automatic change-over switch for DVB Transport Stream signals with seamless
switching capabilities.
•Provides four outputs: two DVB-ASI and two DVB over IP (UDP and RTP with and
without FEC).
• Switches between four signal sources.
• Performs seamless switching.
•Provides a DVB Transport Stream output distributed to four DVB-ASI BNC connectors
and to the Ethernet interface (DVB over IP).
• The failure detection criteria are as follows:
- Signal presence.
- Frame synchronization.
- Megaframe synchronization (only in DVB-T mode).
• Provides an external fault indication GPI input for each of the signal sources.
• Provides three modes of operation: Automatic, Semiautomatic and Manual.
•The main DVB-ASI input is bypassed to one of the output connectors in case of power
loss or module removal.
• The DVB-ASI inputs include automatic equalizers.
• All DVB over IP streams are received and transmitted on the same RJ-45 connector.
• Provides the following front panel indicators:
- Failures in the Transport Stream inputs, the 1 PPS input and the 10MHz input.
- Ethernet interface status.
- Operating mode.
- Selected input.
- Seamless switching capacity.
-Changes in the failure status of the inputs or changes in the selected input that can
also be acoustic.
•Module control and supervision can be done remotely when the mounting frame is
equipped with a communications controller module.
•One UR3000 mounting frame can house up to 12 IPA3000C01 modules. If power supply
redundancy is required and FA3000 or FA3001 modules are used then only 10 modules
can be housed in the mounting frame. If PSU3300 or PSU3301 modules are used for this
purpose then up to 12 modules can be installed.

Albalá Ingenieros | Manual IPA3000C01
• One UR3100 mounting frame can house up to three IPA3000C01 modules.
• Low power.
