 Continuum DVP

™

 eXtra Dense QAM 

Array 24 (XDQA24) is specifically targeted to cable operators 
looking for a high-end, cost and space-efficient edge solution 
for the advanced digital architecture. The Continuum DVP 
XDQA24 supports: XoD, broadcast, switched digital 
broadcast, and data applications. It is a self-contained device 
combining GbE Interfacing, Routing, Multiplexing, QAM 
modulation and up-conversion functions. 
 
Scientific-Atlanta’s DirectRF

™

 technology ensures QAM specifications meeting or exceeding the DOCSIS 

standard 

(1)

. Superior RF performance is especially critical when migrating to IP backbones for distributing 

broadcast services. The Continuum DVP XDQA24 allows one QAM product for narrowcast and broadcast 
services.  
 
The Continuum DVP XDQA24 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 Continuum DVP XDQA24 can be configured via an embedded user interface that can be accessed with a 
standard Web browser. There is a dedicated Ethernet port for system management and control.  An open 
communication protocol (SNMP) is provided to interface with the VOD management system.
