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 
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. 
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.
