Chapter 1 Introducing the XDQA24 System
General
The Continuum DVP eXtra Dense QAM Array 24 (XDQA24) system is a compact
QAM array designed for routing, multiplexing, QAM modulation, and RF
up-conversion and allows participating into XoD, broadcast, and data applications.
Scientific Atlanta’s DirectRF. technology ensures QAM specifications meeting or
exceeding the DOCSIS standard. Superior RF performance is especially critical when
migrating to IP backbones for distributing broadcast services. The XDQA24 system
allows one QAM product for narrowcast and broadcast services.
The XDQA24 system is an ideal bridge between flexible IP and Gigabit Ethernet
based backbone networks and existing QAM set-top boxes. Its hot swappable
modular design allows for scalability by adding QAM cards only when more
capacity is needed. QAM cards are configured automatically when inserted, which
reduces set-up and maintenance time to a minimum. The following illustration
shows the XDQA24 system.

For redundancy reason, the XDQA24 system can be equipped with two power
supply units. This features automatic backup switching without service interruption.
The XDQA24 system also supports GbE loop-through.
