The XDQA24 system is provided with two Gigabit Ethernet ports, which receive up
to 256 IP-encapsulated MPEG2 Single Program Streams (SPTS).

After de-encapsulating and buffering, the switch engine routes a number of input
program streams to the 24 QAM modulators and creates the necessary PSI tables
(PAT and PMT).

The Quad Channel QAM Cards buffer, re-stamp and route the signals to one of the
QAM modulators on the card.
