  • Page 10 2.6 h tPs t h e m o d u l e wo r ks After decoding COFDM-modulated signals, the demodulated data streams and the data stream fed via the ASI socket can be accessed via the integrated TPS module. These data streams, also called transport streams, contain several stations in all their components (video, audio, data and service information), which can be changed using the TPS module.
  • Page 11 s s e m b l y 3.1 i n s ta l l i n g t h e C a s s e t t e – Ensure the head-end station is mounted so it will not be able to vibrate. Avoid, for example, mounting the head-end station onto a lift shaft or any other wall or floor construction that vibrates in a similar way.
  • Page 12 3.2 emC r e g u l at i o n s To comply with the current EMC regulations, it is necessary to connect the lines leading in and out of the head-end station using cable terminals. When mounting the cassette in a head-end station which is installed in a 19" cabinet, make sure the connections leading in and out for the 19" cabinet are made using cable terminals. The attenuation of shielding of the connection lines for ASI and antenna must meet the requirements for "Class A". CLASS • Insert the required number of cable terminals in the openings provided in the head-end station or in the 19" cabinet. —>...
