    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.
  • Page 6 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.

  • Page 7: Features

    • 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.
  • Page 8 Albalá Ingenieros | Manual IPA3000C01 • One UR3100 mounting frame can house up to three IPA3000C01 modules. • Low power.

    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.

  • Page 14: Environmental Considerations

    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.

    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.

    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.

    Albalá Ingenieros | Manual IPA3000C01 3.6.2. GPI connections The GPI inputs use 3.81 mm pitch terminal block connectors and their equivalent 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.

    DVB-T mode) is invalid or when the corresponding GPI for the given input is connected to ground. When an error at the input is produced the IPA3000C01 will only switch to a lower priority input when that input is error-free.

  • Page 22: Operation In Semi-Automatic Mode

    Albalá Ingenieros | Manual IPA3000C01 forces the IPA3000C01 to wait for a given period of time after an input error is cleared before switching to that input. The default recovery time is two seconds. When the IPA3000C01 is operating in a mode other than Generic DVB and with seamless switching a recovery time greater than two seconds may be needed due to the longer periods needed to align the transport streams in non-DVB-T modes.

  • Page 23: Description Of The Ts Over Ip Encapsulators/De-Encapsulators

    RTP protocol a single frame (FEC Type A) or two frames (FEC Type B) of auxiliary data can be sent in order to correct errors or dropped packets. When using the RTP protocol the IPA3000C01 can be configured to substitute dropped and non-recoverable packets of the TS with null packets.
  • Page 24 50 ms greater than the TS input delays received. This difference is due to the response time of the frame synchronization error detectors. When the IPA3000C01 operates in this mode the delay fields in the "General" tab of the control software display the delay of the transport streams received with respect to the 1 PPS reference signal.
  • Page 25 Albalá Ingenieros | Manual IPA3000C01 An additional reason that a small buffer size is recommended when the IPA3000C01 operates in this mode is that buffer size affects the recovery time before seamless switching can be performed. The larger the buffer size the longer the seamless switching recovery time.

  • Page 26: Redundant Ip Transmitter Mode

    4.6. Redundant IP transmitter mode Two IPA3000C01 modules can be configured with the same IP parameters so that they deliver one multicast IP stream with redundancy that cannot be duplicated at any time. This is done by correctly interconnecting the GPIO's of the two modules so that each module signals its status to the other while monitoring the other's status.
  • Page 27 Albalá Ingenieros | Manual IPA3000C01 It's important to configure the output activation delay of the main module to ensure that it does not transmit simultaneously with the reserve module when the signal is recovered. If this is not done, the main module will begin to transmit the IP stream at the same time that it activates its GPO signaling to the reserve module that it should stop transmitting.

  • Page 28: Module Remote Control And Supervision

    Albalá Ingenieros | Manual IPA3000C01 4.7. Module remote control and supervision The IPA3000C01 requires remote control for configuration. In order to perform remote configuration and supervision of the module an optional TL3000 family remote communications controller must be installed in the mounting frame.
