Scientific Atlanta Continuum DVP XDQA24
The Scientific Atlanta Continuum DVP eXtra Dense QAM Array 24 (XDQA24) is one of the edge QAM
devices that has been tested for interoperability with other solution components. The Continuum DVP
XDQA24 has two redundant Gigabit Ethernet input interfaces that use small form-factor
pluggable (SFP) modules for fiber-optic and copper links. It has 24 output QAM channels (12 outputs,
each with two adjacent QAM channels). The Continuum DVP XDQA24 software is customized to
accommodate the requirements of the Cisco Cable Wideband Solution.

The Continuum DVP XDQA24 chassis is a single rack unit high. The Continuum DVP XDQA24 uses
uses hot-swappable, auto-configurable QAM cards containing two QAM channels on a single RF
converter. The Continuum DVP XDQA24 has fully redundant AC or DC power supplies. More detailed
information and part numbers for the Continuum DVP XDQA24 are available at:

Harmonic NSG 9116
The Harmonic Narrowcast Services Gateway (NSG) 9116 is one of the edge QAM devices that has been
tested for interoperability with other solution components. The NSG 9116 has two redundant Gigabit
Ethernet input interfaces that use small form factor (SFP) modules for fiber-optic and copper links. It
has 16 output QAM channels (eight dual QAM output channels). The NSG 9116 software is customized
to accommodate the requirements of the Cisco Cable Wideband Solution.

Harmonic NSG 9000
The Harmonic Narrowcast Services Gateway (NSG) 9000 is one of the edge QAM devices that has been
tested for interoperability with other solution components. The NSG 9000 has three independent Gigabit
Ethernet input interfaces that use small form factor (SFP) modules for fiber-optic and copper links. The
NSG 9000 is DOCSIS 3.0-compliant.
