IQASI25 ASI Transport Stream Switch and DA

The IQASI25 is a cost-effective ASI-switched distribution amplifier that continuously monitors two MPEG-2 DVB ASI transport streams (TS) and routes the preferred input to the five identical outputs. It monitors various critical parameters within the transport stream and their status will effect switching and alarms.

It is compliant to the ETSI TR 101290 specification for Digital Video Broadcasting and supports both DVB and ATSC transport streams in Packet, Byte & Burst modes.

Automatic operation is configurable by the user and the switch may also be externally controlled via the RollCall control and monitoring system or external GPIs.

FEATURES

  • Monitors two ASI inputs for loss of carrier signal, loss of transport stream sync and loss of PAT with automatic input switching on error
  • Designed to minimize switching and prevent unnecessary disruption of the transport stream
  • Remains on an input until that input fails. If the alternate input has also failed, no switch occurs
  • If both inputs return to a good state, the switch remains static on the selected input
  • Manual switch to force the module to Input 1 or 2
  • Two configurable GPIO ports (two in or two out or one of each)
  • LED indicators to show if input 1 is absent, input 2 is absent and if outputs are derived from input 1 or input 2
  • RollCall control and monitoring compatible
