An Important Note About Offline Network Elements
The Alarm Manager server does not monitor network elements that are defined as
offline in the DNCS database.

The Alarm Manager server will not attempt to ping or communicate with Broadband
Integrated Gateways (BIGs), QAMs, MQAMs, GQAMs, or GoQAMs that are defined
as offline. Therefore, if you have BIGs, QAMs, MQAMs, GQAMs, or GoQAMs that
are not ready for use in your DBDS network, our engineers recommend that you
define them as offline in the appropriate DNCS Network Provisioning window.
If one of these devices is defined as online in the DNCS database, but is not
If one of these devices is defined as online in the DNCS database, but is not
physically connected to the DNCS network, is powered off, or is not fully booted, the
Alarm Manager server will generate an alarm stating that it could not communicate
with the device.
A Quadrature Phase-Shift Keying (QPSK) modulator cannot be defined as offline.
A Quadrature Phase-Shift Keying (QPSK) modulator cannot be defined as offline.
However, you may need to add QPSK modulators to your DNCS database that are
not yet ready for use in your DBDS network. For each QPSK modulator that meets
one of the following conditions, the Alarm Manager will generate an alarm stating it
could not communicate with the QPSK modulator:
QPSK modulator is not physically connected to the DBDS network
QPSK modulator is powered off
QPSK modulator is not fully booted
These connection alarms are generated once for each QPSK modulator. You can
quickly remove these alarms from your alarm list by performing an acknowledge
and clear operation. Refer to the DBDS Alarm Manager 1.0 Online Help (part number
745259) , if necessary, for instructions on acknowledging and clearing the alarms.
