With GQAM software version 4.2 or later, GQAM modulators with dual GbE ports
support the VOD Redundancy feature. This feature allows system operators to carry
VOD and Broadcast services on the same GQAM, thereby leveraging the
redundancy capability of the GQAM modulator's dual GbE ports.

Generic QAM Support
This system release adds support to manage provisioning of generic QAMs through
the published interface made available to the QAM vendors.
the published interface made available to the QAM vendors.
A Generic QAM button and a Generic QAM Models button have been added to the
Network Element Provisioning tab. These buttons allow you to add traditional table-
based QAM modulators to the DNCS. (The DNCS refers to these modulators as
generic QAM modulators.) Adding a generic QAM modulator to the DNCS allows
you to set up sessions on the modulator and manage the sessions.

you to set up sessions on the modulator and manage the sessions.
However, unlike session-based modulators, generic QAM modulators do not
support DNCS-supplied provisioning. As a result, specifications saved to the DNCS
when the modulator is added (or provisioned) in the DNCS are not provided to the
modulator when the modulator reboots. Instead, the modulator must be provisioned
separately. For assistance provisioning generic QAM modulators, consult the
documentation provided by the manufacturer of the modulator.
