    1. DESCRIPTION 1.1. The ISW3000C01 The ISW3000C01 module is an automated switch for DVB-ASI and DVB-over-IP streams that operates based upon the presence of signal at its inputs, the status of a diverse set of parameters of the input streams and the information received via a GPI, all based upon the priorities that the user assigns to each input.
  • Page 6 GPO output to signal that the unit cannot deliver a valid TS at the outputs. In addition to functioning as an automatic switch, the ISW3000C01 can be used for other functions such as conversion of DVB-ASI transport streams to DVB over IP and vice...
  • Page 7 SNMP management and the ability to record events in a file including date and time information for further analysis. The ISW3000C01 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 8: 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 ISW3000C01 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.

    ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified with a high degree of shielding for storage and transportation. The ISW3000C01 module is composed of two parts: one IPA3000P11 main board and one IPA3000P10 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 IPA3000P11 board (main board of the ISW3000C01 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 ISW3000C01 module rear board connector layout. Rear view of the ISW3000C01 The ISW3000C01 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 ISW3000C01. 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 ISW3000C01 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.

    First Priority as per ETSI TR 101 290 V1.2.1, presence of the megaframe sync in DVB-T mode and presence of the superframe sync in DVB-T2 mode. When an error at the input is produced the ISW3000C01 will only switch to the other input when that input is error-free.

    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 ISW3000C01 can be configured to substitute dropped and non-recoverable packets of the TS with null packets.

When the ISW3000C01 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 25 256 packets is necessary. When the ISW3000C01 operates in this mode the delay fields in the "General" tab of the control software display the latency of each input. The latency introduced by this buffer affects both the DVB-ASI outputs and the DVB over IP outputs.

  • Page 26: Redundant Ip Transmitter Mode

    4.6. Redundant IP transmitter mode Two ISW3000C01 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 ISW3000C01 Second, invert the polarity of the GPO's of both modules using the control software so that an absence of signal at the output of one module or a module's failure is indicated by an open circuit.

  • Page 28: Module Remote Control And Supervision

    Albalá Ingenieros | Manual ISW3000C01 4.7. Module remote control and supervision The ISW3000C01 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.
