ASI Monitoring Blade


The VB242 ASI input option card allows operators real-time high density ASI monitoring or switched ASI round-robin monitoring for remote or head-end applications. With up to 13 ASI inputs in a 1 RU chassis in combination with the VB220 or VB120 controllers, the VB242 is perfect for existing infrastructures in the head-end and the regional edge-multiplexer/ modulator/ transmitter site. The VB242 complements the already extensive range of input interfaces for the VideoBRIDGE series probes.

The VB242 interface module can operate in two different modes: either two of the inputs are monitored full time with continuous ETSI TR 101 290 analysis, or its six inputs are sequentially monitored in a round-robin fashion.

Using two VB242 interface modules in a 1RU chassis allows full time monitoring of five ASI streams in parallel – two streams from each of the interface modules and one stream from the ASI input of the controlling VB120 or VB220 probe. This high density solution is very useful for monitoring in head-ends where ASI infrastructure is used. It is also possible to combine a VB242 with a different input interface module, for instance one of the demodulators in the VideoBRIDGE interface product range.
